Abstract:
At the center of the Transyvanian Plateau lies Ocna Sibiului, with its salt deposits which, in places, run up to one thousand meters below the surface. The presence of these deposits has been favored, due the extraction of salt throughout the years causing the formation of the now famous salt lakes. Due to different environmental conditions, lacustrine cuvettes and water quality differ from one lake to another. The studied lakes are considered to be in conection with the salt deposits exposed through minig activities carried on in different time periods. Other lakes in the area already are isolated from salt deposits due to natural sedimentation proceses. The study adresses the lakes which still present a high degree of salinity and are used for balnear purposes, and present, due to various factors, variation of physical-chemical composition throughout the year. Water samples were collected from the main six lakes in Ocna Sibiului (Ocniţa - Avram Iancu; Rândunica; Negru; Fără Fund; Brâncoveanu and Gura Minei). Surveys were carried out in four periods (March-November) during 2012.Water temperature, electrical conductivity (at 25°C) and pH were measured in-situ. The water pH changed from a lake to another. Generally it is within the range of 6.78 to 8.8 highlighting the neutral to slightly alkaline lake water. Salt lake water conductivity values, in the upper layers vary within a wide range, from more than 200 mS cm-1 to 45.7 mS cm-1, with different values from the different lacustrine units. The salt water lakes are characterized by high content of sodium and chlorine ions. The other major ions are present in a small amount. This paper aims to compare the past and present evolution, characteristics and environment of these lakes, , and, based on this and current research, to project a vision of their future and how it will affect the lives of future generations living besides them.

Abstract:
A large number of different-sized lakes exist in the inland area of the Tibetan Plateau (TP), which are examples of the important connection between the atmosphere and hydrosphere through the analysis of lake surface convergence and evaporation processes. The evaporation level changes that occur in middle–large-sized lakes (surface area > 50 km2) in the area directly influence the regional mass and energy balance values, atmospheric boundary layer heat and humidity structures, and weather processes occurring in the lower-reach areas. The studies conducted in the literature at present, concerning lake evaporation processes, generally overlook the differences in lake heat storage behavior due to the reduced amount of data in the literature concerning lake bathymetry. According to the in situ bathymetric data obtained for 68 middle–large-sized lakes in the inner basin of the TP, in this study, we calculated their heat storage (G) change values by using the different vertical-depth water-temperature-change integral method, and we established a regression equation for the heat storage and lake surface net radiation values for 68 lakes. The evaporation rates of 134 middle–large-sized lakes larger than 50 km2 in the inland are of the TP were calculated by obtaining the G regression result and adopting it into the Penman model, as well as estimating the evaporation losses of theses 134 lakes from 2002 to 2018. The result shows that the annual average evaporation rate for these lakes is 927.39 mm/year, with an insignificant upward trend (0.10 mm/year). This method achieved good accuracy compared with the Bowen ratio method, which estimates the evaporation rate during the ice-free season, with a high correlation coefficient (R) value of 0.95 and least root mean square error (RMSE) value of 61 mm. The annual mean evaporation rate can be divided into the southern and northern lake groups along a 34°N line with a difference of 314.41 mm/year. The annual average evaporation volume of these lakes was 25.02 km3 and showed an upward trend of 0.35 km3/year. Among them, the annual average evaporation volume contribution ratio of level-1 lakes (50 km2 ≤ lake’s area < 100 km2, 61 lakes) was 14.04%, showing an upward trend, and the contribution of level-3 lakes (lake’s area ≥ 500 km2, 10 lakes) was 41.50%, showing a downward trend. There were no obvious changes in the level-2 lakes (100 km2 ≤ lake’s area < 500 km2, 63 lakes), which maintained at the same level in approximately 44.46%. Air temperature is the most important factor affecting the evaporation rate of lakes, while the lake surface area is the main factor affecting lake evaporation volume. Our study, considering the actual lake heat storage value, provides a useful reference for further improving lake water budget balance values and watershed hydrologic features in the inland closed lakes located in the TP.

Abstract:
Fish introductions in Africa have been made at various spatial scales from small fish ponds to the largest lakes, primarily to sustain or increase production, though some were to develop sport fisheries and to control unwanted organisms. Some introductions have fulfilled their objective in the short term, but several "successful" introductions have created uncertainties about their long-term sustainability. Lates niloticus, Oreochromis niloticus, O. leucostictus, Tilapia melanopleura and T. zilli were introduced into Lakes Victoria and Kyoga in 1950's and early 1960's; by the 1980's L. niloticus and O. niloticus dominated the fisheries, having virtually eliminated a number of endemic species. In Lake Victoria, the loss of genetic diversity has been accompanied by a loss of trophic diversity; the transformation of the fish community coincided with profound eutrophication (algal blooms, fish kills, hypolimnetic anoxia) which might be related to alterations of the lake's food-web structure. By contrast, the introduction of a planktivore, Limnothrissa miodon into Lake Kivu and the Kariba reservoir has established highly successful fisheries with little effect on the pre-existing fish community or trophic ecology. The endemic species-rich African Great Lakes may be particularly sensitive to introductions. Species extinctions, introgressive hybridization and ecosystem alterations may occur following introductions.

Abstract:
Water quality was monitored in Boreal Shield lakes for 3 years following their simultaneous impact by clearcut logging or wildfire. Seventeen similar undisturbed lakes served as references. Dissolved organic carbon (DOC) and the light attenuation coefficient (εPAR) were up to threefold higher in cut lakes than in reference and burnt lakes. Compared with median values for reference lakes, cut and burnt lakes had higher concentrations of total phosphorus (TP) (two- to three-fold), total organic nitrogen (TON) (twofold), and K+, Cl-, and Ca2+ (up to sixfold). NO3- and SO42- concentrations were up to 60- and 6-fold higher, respectively, in burnt lakes than in reference and cut lakes. In most cases, impacts were directly proportional to the area harvested or burnt divided by the lake's volume or area. These simple models correctly predicted the changes observed in three lakes harvested during the study. Some of the ob served effects occur on different time scales. Mobile ions released by fire (K+, Cl-, SO42-, NO3-) or harvesting (K+, Cl-, some DOC) are rapidly flushed out of the watershed (50% decrease in 3 years). Other constituents or properties (TP, TON, DOC, εPAR, Ca2+, Mg2+) show little change or are still increasing after 3 years and will take a longer time to reach normal levels.

Abstract:
Abstract Microplastic pollution in the marine and freshwater environment has been a global concern. The pollution in densely populated urban areas may be more severe than in any other environment, especially in areas lacking plastic waste management. Urban lakes in the Megacity of Jakarta, the capital city of Indonesia, and neighboring areas, which is the most populated city in the world, have been severely polluted by plastic waste. The urban lakes studied were located downstream of watershed areas of major rivers that outflow into Jakarta Bay, the Java Sea, and finally the ocean. To our knowledge, no studies have been reported on microplastic pollution in urban lakes in the Megacity of Jakarta. This study investigated the first occurrence of microplastics in the surface water of six urban lakes in the Megacity of Jakarta. Grab water samples were collected in either inlet or outlet areas of lakes. The water samples were pretreated and sieved to separate the microplastics. The quantification and the identification of microplastics were made using a Stereo Microscope. The most downstream urban lakes in the densely populated area close to Jakarta Bay, which is the final disposal of plastic wastes from the river canal and runoff from the surrounding area, had more microplastics than the urban lakes in the area with less population and further from the Bay. The most abundant microplastics found in the lake’s surface water was about 30,000 particles/m3, whereas 300 - 500 µm and the foam were the dominant size and type of microplastics discovered. The concern is that the smallest size of particles of microplastics found in the lake’s water could potentially contaminate aquatic biota, especially fish, not only in the lakes but also in Jakarta Bay, where fishing activities are substantial.

Full text
Abstract:
Small lakes within social sciences’ conceptualisation are mostly wanting, less anchored and seldom scrutinised in academic literature as opposed to large lakes and natural sciences. Essentially, small lakes, from a social sciences’ perspective, are about people connecting and enhancing through lake governance. Thus, the main argument is that a small lake’s people must accept, broaden and elevate the prospect of lake governance by focusing on and embracing the central concepts of government—the most compulsory and crucial constituent—as well as premier leader—the most pre-eminent and imperative function. Accordingly, lake governance refers to engaging with and intervening in the collective people of a small lake, to undertake economic development, pursue ecological conservation and manage government. Government refers to steering a small lake’s people towards emphasising executive authority and decision-making power, whether through solutions, policies, regulations and/or implementations. The premier leader refers to the person presiding over a small lake’s people in the critical aspects of resoluteness—in establishing and sustaining the rules—and decisiveness—in settling and determining a community’s issues. Overall, as small lakes’ people are political, lake governance is consequential, and a government/premier leader is evidently the most efficacious outcome, whether for addressing problems, choosing decisions or ameliorating society.

Full text
Abstract:
Ballast water is recognized globally as a major vector of aquatic nonindigenous species (NIS) introductions; domestic ballast water transfers, however, have generally been considered low risk in North America. We characterize ballast operations of domestic ships in the Great Lakes – St. Lawrence River system (Lakers) during 2005–2007 to examine the risk of primary and secondary introductions associated with ballast water transfers over short distances. Results indicate that Lakers transported at least 68 million tonnes of ballast water annually. Approximately 71% of ballast water transfers were interregional, with net movement being from lower to upper lakes. A small proportion of ballast water discharged in the Great Lakes (<1%) originated from ports in the St. Lawrence River that may serve as sources for new NIS. These results indicate that domestic ballast water transfers may contribute to NIS introductions and are likely the most important ballast-mediated pathway of secondary spread within the Great Lakes. Future efforts to reduce invasion impacts should consider both primary and secondary introduction mechanisms.

Abstract:
I monitored Common Loon (Gavia immer) breeding success in relation to lake pH (range 4.0–8.5) between 1982 and 2007 on 38 single-pair lakes (5–88 ha) in the Sudbury, Ontario, area. No chicks fledged on lakes with pH < 4.4. Chicks fledged on lakes with slightly higher pH only if the lakes were relatively large. Acidic lakes became less acidic as sulphur dioxide emissions from the Sudbury smelters and sulphur deposition from other long-range sources decreased. Two lakes initially too acidic to support successful loon reproduction eventually had successful reproduction. One loon pair used two large acidic lakes (combined area 140 ha) connected by shallow rapids, and one of the adults made extremely long dives (average = 99 s) while foraging for the chicks. One chick died on that lake after apparently ingesting a very large food item; the lack of smaller items was attributed to the lake’s acidity. My results suggest that a shortage of food for chicks is the main reason why low pH reduces breeding success. I suggest that, for lakes without high levels of dissolved organic carbon (DOC), the critical pH for loon breeding success is approximately 4.3, and the suboptimal pH is approximately 4.4–6.0.

Abstract:
In this paper, we present the current situation of the Gosainkunda and associated lakes based on the preparation of an inventory of lakes using the Google Earth Engine and 2020 Sentinel 2A satellite imagery. Furthermore, we discuss the hydrology, hydrochemistry, and cultural significance of the lakes based on the systematic review of available literatures. In 2020, there are 22 lakes along with Gosaikunda (12.7±0.4 ha) in the Upper Trishuli watershed (59.2 km2), extending from 1274 to 4993 m elevation and covering a total area of 80 ha. The largest lake is Bhairabkunda, with an area of 15.5±0.5 ha. The water bodies in the region are drying, and some of the lakes have already disappeared from the region. But some lakes in the region are evolving as temporary water bodies. The high-altitude lakes are sensitive indicators of anthropogenic disturbance and changing climate. Though the lakes have better hydrochemical quality than the urban lakes located in the southern part of the country, the evidence shows increasing local and long-range transport and deposition of the pollutants in the lake water. The presence of chemical constituents of anthropogenic sources in the water of oligotrophic lakes is possibly evidence of the long-range transport of pollutants. Considering the cultural importance of the region, the number of visitors is increasing annually. Increasing human activities in and around the lake, long-range transport of pollutants, and changing environment in the area are demanding for the lake's conservation. We suggest regular monitoring of the high-altitude lakes to understand the ongoing climate change and anthropogenic impacts.

Abstract:
Cyanobacterial blooms and their toxins are a major water quality and potential health risk around the world. This thesis developed an analytical method for microcystin congeners in sediments in order to examine their fate in lakes and establish the history of toxin-producing cyanobacteria in relation to environmental change using lake sediments. A novel method for both intra- and extracellular microcystins in lake sediments was developed, consisting of accelerated solvent extraction, hydrophilic-lipophilic balance solid phase extraction and multiple reaction monitoring-based HPLC-MS/MS quantitation. The method achieved comparable recoveries of intra- and extracellular cyanotoxins based on nine microcystins and nodularin (marine analogue). The analytical method was validated using surficial and deeper sediments from seven lakes of diverse geography and trophic state. To study the fate of microcystins, a multi-year, whole lake study of Microcystis blooms was conducted to obtain both in situ and in vitro half-life estimates of microcystin-LA (MC-LA), an understudied, but increasingly reported microcystin. MC-LA appeared to undergo slower rates of decomposition and persist longer than the more frequently studied MC-LR. Experimentally, high light intensity increased in vitro decomposition of dissolved MC-LA while high temperature enhanced decomposition in the particulate phase. Sediment deposition measurements and estimates of sediment-pore water distribution coefficients, sediment accumulation rates, and diffusive fluxes indicated that microcystin congeners differ in their fate. Notably, MC-LA preferentially distributed into pore water and remobilized (by diffusion) from sediments and into overlying water while MC-RR adsorbed more strongly to sediment particles. Finally, the sediment record of an eutrophic lake of major recreational importance was examined to identify possible drivers of toxigenic cyanobacteria and determine if the perceived increase in toxigenic cyanobacteria could be corroborated. Microcystins were detected to the bottom of the core (early 1800s), indicating that toxigenic cyanobacteria were present prior to the first permanent settlements. Microcystins were significantly correlated with changes in diatom-inferred nutrients (DI-TP and DI-TKN) within the sediment core as well as with specific algal pigments. Sediment microcystins in the upper layers also significantly correlated with a 20-year monitoring record for water column microcystins suggesting that sediment microcystins can be used as a proxy for past surface water conditions.

Full text
Abstract:
Approximately 14,500 years ago, Pleistocene Lake Bonneville discharged 4750 km 3 of water over the divide between the closed Bonneville Basin and the watershed of the Snake River. The resulting flood, emanating from the divide at Red Rock Pass, Idaho, followed the present courses of Marsh Creek, the Portneuf River, and the Snake and Columbia Rivers before reaching the Pacific Ocean. For the 1100 kilometers between Red Rock Pass and Lewiston, Idaho, the Bonneville Flood left a spectacular array of flood features that have allowed for geologic reconstruction and quantitative evaluation of many aspects of the flood hydrology, hydraulics, and sediment transport. Geologic evidence of maximum flood stages in conjunction with step-backwater modeling provides for peak discharge estimates and understanding of local hydraulic flow conditions for ten separate reaches along the flood route. Peak discharge was approximately 1.0 million m³•sec⁻¹ at the Lake Bonneville outlet near Red Rock Pass. Downstream, the maximum discharge had attenuated to 0.57-0.62 million m³•sec⁻¹ by arrival at Lewiston. Attenuation was primarily the result of flow storage in the wide alluvial valleys of the western Snake River Plain. The local hydraulic conditions (depth and velocity) of the Bonneville Flood varied significantly within and between the study reaches. The rate of energy expenditure was also highly varied; local calculated stream-power values ranged from less than 10 watts•m² to 100,000 watts•m². Greater than 60% of the total energy loss at peak discharge was expended in a total distance that encompassed less than 10% of the flood route. These spatial variations in local hydraulic conditions were profoundly important in controlling the distribution of flood processes and features. The deposition of tractively-transported cobbles and boulders (measured diameters ranged from less than 10 cm to greater than 10 m) occurred in reaches of decreasing flow energy within quantitatively-definable limits of flow energy. Areas of erosion are more difficult to precisely evaluate; however, they were restricted to reaches of greater stream power. It is likely that cavitation was an important erosional agent in many areas of most intense flow conditions.

In 81st International Scientific Conference of the University of Latvia. University of Latvia, 2023. http://dx.doi.org/10.22364/iarb.2023.05.

Full text
Abstract:
Macroinvertebrates and macrophytes were used as indicators to assess the ecological quality of five Latvian-Lithuanian transboundary lakes. The aim of the study is to ensure joint quality assessment of trans-boundary lake water bodies, because studied lakes pose a risk for not meeting good status according to the requirements of the EU Water Framework Directive. The fieldwork was performed in May and October 2021. Macroinvertebrates demonstarted good ecological quality at all studied lakes using both Latvian and Lithuanian multimetric macroinvertebrate indices. The non-biting midges Chironomidae, as well as the mayfly species Caenis horaria and Cloeon dipterum, were dominant in macroinvertebrate communities of the studied lakes. The invasive species zebra mussel Dreissena polymorpha was present in four lakes while the spiny-cheek crayfish Orconectes limosus was observed in two out of five lakes. In addition, the medical leech Hirudo medicinalis was found in Lake Lielais Kumpinišķu; it is a species protected under the Habitats directive (Annex V) and under the Latvian Regulation of the Cabinet of Ministers No 396.

Abstract:
Changes in the ecosystems of lakes and their shores caused by anthropogenic impact have a huge influence on the quality of the landscape. The article analyzes the inflow of biogenic substances into lakes Lūkstas and Paršežeris. The spread of Quaternary sediments of lake basins, land use distribution, ongoing economic activities, activity planning and the effectiveness of water conservation measures in the dry year of 2020 was analyzed to study in detail. The planned and actual amounts of biogenic substances entering the lakes through seven surface water tributaries were evaluated. It has been established that the environmental protection measures implemented in the Lūkstas and Paršežeris lakes basins over the last decade are effective. Calculations and analysis of the loads of biogenic materials in the investigated lake tributary basins based on the results of natural studies showed that the values of biogenic material loads do not exceed the values modeled in the modeling done in the work and in the river basin management plans.

Abstract:
Palic and Ludas lakes are located in the northern part of Vojvodina, Serbia near the town of Subotica, just a few kilometers south of the Hungarian border. While Palic lake has a long history as a tourist attraction and a nice recreational setting, Ludas lake and the surrounding steppe plains are habitats of international importance and protected by the Ramsar convention on wetlands. The lakes are connected through the Palic-Ludas canal. Thus Ludas lake is fed partially from Palic lake, but also supplied by the Körös river. The majority of the catchment area of the Körös river is in Hungary, this way the water supply problems related to the lakes are transboundary. The lake system is also drained by the Körös, which finally enters the Tisza river. Water quality problems and water quantity decrease are both identified and are escalating threatening factors at the lake system in the past decades. Several studies have been carried out in the past about the possible reasons and solutions. The authors have studied the previously published results and have been participating in a cross-border cooperation project funded by the IPA, in frame of which a comprehensive survey and measurement program has been carried out in order to develop, among others, a rainfall-runoff model of the catchment for the investigation of water supply scenarios of the lake system in order to substantiate a monitoring network and program for the sustainable management of the lakes. In our article we introduce the area, the problem, the field surveying and measurement methodologies and results, the modeling process and the model itself, concluding transboundary responsibility for water supply to the lake system, with a possible complex connection to one of Hungary’s major water management issues.

Abstract:
New data were received on infection with Kinetoplastida of the family Trypanosomatidae in fish of various taxonomic groups in lakes in the Republic of Buryatia (Eastern Siberia). Kinetoplastids of the genus Trypanosoma recorded in the river perch, common pike, sand sculpin, Siberian loach, crucian carp, and Siberian roach were characterized by the greatest host diversity. The roach (Gusinoe Lake) is recorded for the first time for the Baikal basin as a host for hemoflagellates of this genus. Blood parasites of the genus Trypanoplasma were found in 3 fish species: the pike, perch, and sand sculpin. A clear trend was noted for the increasing infection level in the perch and pike of Gusinoe Lake over a 40-year period. The dace, Amur carp, Amur catfish, burbot, Amur sleeper, and common minnow from Gusinoe Lake were free from blood parasites Trypanosoma sp. and Trypanoplasma sp. Kinetoplastids were not found in roaches from Tsaidam, Shchuchye, Torma, Kotokelskoe and Bolshoye Kicherskoe Lakes. The analysis showed no infection with kinetoplastids in the roach, dace, Baunt whitefish, humpback whitefish, Siberian cisco, perch, burbot, ruff, and pike in the reservoirs of the Baunt Lakes system (Bolshoe Kopylyushi Lake, Maloe Kopylyushi Lake, Baunt Lake, the Lena basin), and crucian carp in reservoirs Klyukvennaya Pad, Cheremukhovoye Lake and Nikitkino Lake (Baikal basin).

Abstract:
This paper presents the findings of the mapping and evaluation of macrophyte vegetation from Tataru and Uzlina lakes, located within Danube Delta, Romania. Throughout time, the Danube Delta unique ecosystem has endured considerable ecological changes due to natural and anthropogenic stressors. Currently, the potential threats are those related to pollution, agriculture, land use, climate change and subsequently, the proliferation and/or the extinction of many macrophyte species. The excessive development of aquatic vegetation has negative consequences, reducing the flow velocity of water in the connecting channels, exacerbates the sedimentation processes in the deltaic lakes which are subject to the clogging phenomenon (i.e., silting). The abundance, distribution and biodiversity of the emergent aquatic species were surveyed in Tataru and Uzlina lakes. The biodiversity of macrophytes is different in the investigated lakes, being dependent on the fluvial input of water and sediment of the Danube River, extent of lakes and water depth. In Tataru Lake, the macrophyte vegetation was represented by a greater variety of species (Nymphaea alba, Nuphar lutea, Trapa natans, Salvinia natans, Lemna minor and Phragmites australis), in comparison to Uzlina Lake (Nymphaea alba, Nuphar lutea, Trapa natans and Phragmites australis). This methodology and results are valuable for the strategic environmental assessment and management of the Danube Delta Biosphere Reserve and can be used in similar settings.

Full text
Abstract:
ABSTRACT The western branch of the East African Rift is characterized by modest amounts of extension and by deeply-subsided, fault-controlled basins filled with large, deep lakes. Lakes Tanganyika and Nyasa (Malawi) are two of the largest lakes in the world, with maximum water depths of 1450 and 700 m respectively. Newly acquired seismic reflection data, along with newly reprocessed legacy data reveal thick sedimentary sections, in excess of 5 km in some localities. The 1980's vintage legacy data from Project PROBE have been reprocessed through pre-stack depth migration in Lake Tanganyika, and similar reprocessing of legacy data from Lake Nyasa (Malawi) is underway. New high-fold and large-source commercial data have recently been collected in southern Lake Tanganyika, and new academic data have been acquired in the northern and central basins of Lake Nyasa (Malawi) as part of the 2015 SEGMeNT project. In the case of Lake Tanganyika, new data indicate the presence of older sediment packages that underlie previously identified "pre-rift" basement (the "Nyanja Event"). These episodes of sedimentation and extension may substantially predate the modern lake. These deep stratal reflections are absent in many localites, possibly on account of attenuation of the acoustic signal. However in one area of southern Lake Tanganyika, the newly-observed deep strata extend axially for ~70 km, likely representing deposits from a discrete paleolake. The high-amplitude Nyanja Event is interpreted as the onset of late-Cenozoic rifting, and the changing character of the overlying depositional sequences reflects increasing relief in the rift valley, as well as the variability of fluvial inputs, and the intermittent connectivity of upstream lake catchments. Earlier Tanganyika sequences are dominated by shallow lake and fluvial-lacustrine facies, whereas later sequences are characterized by extensive gravity flow deposition in deep water, and pronounced erosion and incision in shallow water depths and on littoral platforms. The age and provenance of the sub-Nyanja Event sequences is unknown, but may correlate to Miocene, Cretaceous or Karroo-age sedimentary packages documented elsewhere in the southwestern part of the East African Rift, including in the region around Lakes Rukwa and Nyasa (Malawi).

Full text
Abstract:
The northern coastal plain of Bering Land Bridge National Preserve (BELA) lost lakes at an alarming rate over the first two decades of this century, including four lakes over 100 ha in size in 2018-2019 alone. To understand the effects of these lake drainages, we sampled vegetation of these lakes in 2019 (a reconnaissance visit) and 2021 (for the installation of permanent vegetation monitoring plots). We used these data to summarize the changes that occurred in the first three years after drainage, and to create vegetation maps from 3-m resolution satellite images coinciding with the visit dates. We used time series of these satellite images to study the rate of drainage and vegetation colonization on the lakes. We analyzed our existing data from older drained lake basins (estimated to be more than 200 years since drainage) and reviewed the literature on vegetation change in drained lakes to understand the vegetation changes that are likely in the future. Finally, we used a model of lake occupancy by loons developed by Mizel et al. (2021) to predict the effect of the 2018-2019 lake drainages on available loon habitat, using both our detailed maps of the four sampled drained lakes, and also data on all drained lakes over most of northern BELA derived from Landsat satellite images. Our results show that the four study lakes drained early in the summer, before the end of June, in 2018 (3 lakes) and 2019 (one lake). A combination of record warm weather and heavy snowfall made 2018 and 2019 especially favorable for lake drainage: thaw subsidence probably enlarged existing drainage outlet channels from the lakes, and large amounts of spring snowmelt runoff deepened the outlet channels by thermal erosion (the combination of thaw and erosion). Drainage exposed moist loamy sediment on the lake bottoms that was rapidly colonized by plants. Substantial vegetation cover developed by late summer in the same year as lake drainage in one lake, in the first post-drainage summer in a second lake, and during the 2nd year after drainage in the remaining two lakes. The first vegetation communities to develop consisted of just one or two dominant species, notably Eleocharis acicularis (spike rush), Equisetum arvense (horsetail), and/or Tephroseris palustris (mastodon flower). Other important early species were Arctophila fulva (pendant grass) and Rorippa palustris (yellow cress). By year 3, the communities had become more diverse, with significant cover by taller wetland graminoid species, including A. fulva, Eriophorum scheuchzeri, and Carex aquatilis. Frozen soil was observed in most locations on the lakes in July of 2021, suggesting that permafrost was forming on the lake bottoms. Comparison of the three-year trends in vegetation change with data from older lake basins suggest that ultimately most lake basins will develop wet tundra communities dominated by Carex aquatilis and mosses, with various low shrub species on acid, peat-dominated soils and permafrost; however, this process should take several centuries. The loon habitat model suggests that drainage essentially eliminated the potential habitat for Yellow-billed Loons on the four study lakes, because the residuals ponds were too small for Yellow-billed Loons to take flight from. A total of 17 lakes drained in northern BELA in 2018-2019. As a result, the potential Yellow-billed Loon nesting habitat in northern BELA probably decreased by approximately 2%, while habitat for Pacific Loons decreased less, by about 0.6%. Habitat for the more abundant Red-throated Loons probably increased slightly as a result of lake drainage, because of their ability to use the small residual ponds created by lake drainage.

Full text
Abstract:
S?t? Tlein (Tlingit for ?Big Glacier?) is the traditional name for what has recently been called Malaspina Glacier, the largest glacier in Alaska. The piedmont terminal lobe of S?t? Tlein is protected from the adjacent Pacific Ocean by a narrow, vegetated foreland dotted with proglacial lakes. Ice of the piedmont lobe is largely covered with debris and vegetation. These lakes and sedimentary deposits impact rates of melt and calving and therefore impact ongoing evolution of the glacier itself. To document these features, we present 1) a new surficial geology map for the foreland and piedmont lobe of S?t? Tlein (an area of 3477 km2) at a scale of 1:24,000, and 2) a detailed time-series of proglacial lake extents. The surficial geology is referenced to a 2012 IFSAR Digital Terrain Model with 5-m resolution, supplemented with additional satellite images, maps, and digital elevation models. We visited the foreland in 2021 to ground-truth portions of the mapped area. Lake outlines were digitized from Landsat imagery, focusing on lakes adjacent to the central ?Seward Lobe? of S?t? Tlein. A majority of the mapping area is occupied by glacier ice, a sizable fraction of which is covered by supraglacial debris of varying thicknesses. Off glacier, in the foreland, glacial outwash is the most common mapping unit, followed by moraines of varying ages and finally by marine beaches, bars, and lagoons. Perhaps surprisingly, given significant changes in the glacier itself over the last half-century, these deposits have not changed dramatically since a similar map was produced by Plafker and Miller in 1958. The most significant changes we found are related to lake development. Other than Malaspina Lake, the largest and most persistent lake in the foreland, proglacial lakes were uncommon in the foreland in 1958. Our mapping shows that lake numbers on the Seward Lobe increased from 5 to more than 200 between 1972 and 2020. Most of the new thermokarst lakes are small, compared to Malaspina Lake, but may be having strong impacts on the future evolution of S?t? Tlein. One of these new lakes, Sitkagi Lagoon, is ice-walled and receives input from the Pacific Ocean, portending the possible initiation of catastrophic tidewater glacier retreat.

Department of Aquatic Resources, Swedish University of Agricultural Sciences, 2024. http://dx.doi.org/10.54612/a.5qdiolcgj2.

Full text
Abstract:
Smelts play a key role in the pelagic ecosystem of large lakes in northern Europe and North America. In numbers, they often dominate the open water. In large lakes in Scandinavia (including Finland), European smelt (Osmerus eperlanus L.), a cold-water glacial relict, is commonly the most important prey for piscivorous fish species, but also acts by ontogenetic shifts as a predator on zoo-plankton, small crustaceans, fish larvae, mysids and occasionally – with increasing size - fish. Furthermore, the large numbers of smelt in the open water are important competitors to other planktivorous fish. Due to the diverse life histories and biological interactions of smelt in large lakes, its role in the food-web structure is expected to be variable. Smelt population dynamics, recruitment, size and age structure, growth, life history and mortality were analysed and compared for five Swedish lakes that varied in size, depth, morphology, trophic status and latitude to understand the varying life histories and roles in lake food-webs. The results showed that in shallow, eutrophic lakes smelt stayed small and short-lived, and populations experienced high mortality. In deeper, colder and less nutrient-rich lakes, smelts grew larger and older, and might shift to a piscivorous trophic level. By ontogenetic adaptions smelt seems to uphold high abundance and recruitment over a wide range of ecosystems, but in shallow lakes without cold water refuges smelt populations run the risk of collapsing on the occasion of extremely warm summers with drastic consequences for their predators and lake ecosystems.

Full text
Abstract:
Voyageurs National Park (VNP) is a water-based park that includes part or all of four large lakes and twenty-six smaller lakes commonly referred to as “interior lakes”. The 26 interior lakes of VNP are important aquatic resources with differing size and depth, water chemistry, trophic status, fish communities, and visitor use. Despite the remote location of these lakes, they have been impacted by multiple stressors, including contaminants and non-native species. This assessment provides key information in support of a science-based management plan for these lakes. The objectives of this assessment were to: 1) assess the status of each of the interior lakes and categorically rank the lakes from least to most impacted; 2) use the results to make specific science-based management and restoration recommendations for the most impacted lakes; and 3) make general recommendations that may be useful in managing all of Voyageurs National Park’s interior lakes. When all factors considered in this analysis (water quality, fish mercury concentrations, and fish community characteristics) were combined and assessed, thirteen lakes were classified as most impacted, nine as moderately impacted, and three as least impacted. Although nearly half of the lakes were classified as most impacted in this assessment, many of these lakes are in excellent condition compared to other lakes in the region. The factor-by-factor impact status of the lakes was considered to help describe the condition of the lakes and the potential for restoration. No local management options were identified to mitigate the mercury contamination in these lakes as research has shown the sources of the contamination to arrive from regional and global sources. Similarly, no management actions were identified to reduce nutrient concentrations in the lakes ranked most impacted for nutrient conditions as these are remote lakes with minimal or no development within their watersheds, and it was also noted that paleolimnological studies have shown that the nutrient status of the interior lakes was relatively unchanged from pre-European settlement conditions. Finally, for the lakes in which presumed introduced fish species are present, piscicides were considered as a potential management action. Piscicides were not recommended as a strategy to eradicate introduced fish species as it was determined that genetic conservation of the populations of native fish species still present in these lakes was more valuable than eradicating the introduced species.

Full text
Abstract:
The oldest regional ice flow in the Nose Lake map area is southwestward. Subsequent northwestward flow is inferred from streamlined bedrock in central and eastern regions. The final and youngest flow was southwestward in these same regions, recorded by an abundance of streamlined landforms in till blanket and bedrock. The western edge of this late active ice lobe is defined by recessional moraines, part of the Twin Jugs moraine, also marking the eastern limit of a broad band of hummocky till from downwasting ice. During deglaciation, short-lived proglacial lakes, identified by raised beaches and deltas, developed within parts of the river valleys of the Mara (420 to 410 m elevation), Hackett (445 to 395 m), and Storak (440 to 415 m). Lakes also formed west of Nose Lake (490 to 430 m elevation) and in the Contwoyto-Pellatt-Ghurka lake basins (470 to 450 m). Orientation of many eskers, associated subglacial meltwater corridors, and sheet drainage is variable, but can be perpendicular to local ice flow.

Full text
Abstract:
The ca. 1.75 to 1.27 Ga Hornby Bay intracontinental basin, in northwestern Canada, includes the Big Bear, Mountain Lake, and Dismal Lakes groups. This paper investigates the original depositional environments, paleogeography, and architecture of these groups and how they correlate in time and space. The Big Bear group comprises mainly immature clastic rocks deposited by high-energy rivers, the overlying Mountain Lake group was deposited by westerly flowing rivers over a much broader region, and, following tectonic uplift and erosion, basal clastic rocks of the Dismal Lakes Group were deposited in fluvial and then shallow-marine to paralic environments. Detrital zircon geochronology of sandstone units from the Mountain Lake group of Hornby Bay Basin and Wernecke Supergroup in the Wernecke Mountains supports their correlation and the conclusion that they represent the terrestrial and marine components, respectively, of a west-facing, passive-margin clastic wedge that evolved to a stable carbonate platform. These relationships imply further westward extension of a continental drainage system.

The proliferation and shoreline accumulation of the filamentous biphasic cyanobacterium, Microseira wollei (M. wollei) (previously classified as Lyngbya wollei), have become an increasing problem in the Great Lakes, both for aesthetic reasons and its potential to harbor harmful bacteria and pathogens (Vijayavel et al. 2013). Occurrences have been reported and studies have also been conducted in the southeastern US where M. wollei has become a nuisance in recent years and is known to produce toxins (Hudon et al. 2014). Reports of M. wollei proliferations in the eastern US have been identified in the Manitoba lakes (Macbeth 2004), in Lake Erie from Maumee Bay (Bridgeman and Penamon 2010), in Lake St. Clair near Detroit (Vijayavel et al. 2013), and throughout the St Lawrence River (Vis et al. 2008; Lévesque et al. 2012). M. wollei has become a serious nuisance for marinas, public beaches, and lakefront property owners. In addition, M. wollei appears to have the ability to produce a wide range of toxins, but the conditions promoting their production, type, and concentration are poorly known (Hudon et al. 2014). Occurrences of large algal mats matching characteristics of M. wollei have been observed along the northwest shore and nearshore waters of the beach at Lake St. Clair dating back to 2010. To date, a comprehensive study detailing the potential impacts M. wollei has on freshwater ecosystems in the Great Lakes River, particularly Lake St. Clair is lacking. Further, management solutions are not well understood. This technical note (TN) reviews the potential causes of M. wollei blooms and their ecological impacts on aquatic systems and assesses the management options available to eliminate or minimize the impacts of these blooms.
