The Using Watershed Assessments to Inform Planning for Rural Watersheds publication provides a process for developing a baseline watershed assessment. In this guide we provide recommendations for engaging with stakeholders to assess natural resource conditions, as well as basic information to collect to create a baseline assessment. Watershed planning is not a simple, quick process. This guide addresses just the first steps of building a watershed assessment– understanding the current conditions and issues facing your watershed. Beyond the watershed assessment phase is the hard work of utilizing the information from the assessment, along with the results of additional stakeholder feedback, to develop an actual watershed plan. This guide provides an outline of how to complete the watershed assessment portion of your watershed planning effort, but does not provide a detailed step-by-step process. Rather, this document is intended as a resource to help guide you in your efforts by providing suggestions based on real-world watershed planning experience.

Kansas watershed projects have been responsible for reducing floodwater damage across the state since the formation of watershed districts, following the Kansas Watershed District Act of 1953. A total of 80 organized watershed districts now take on the responsibilities associated with watershed management and protecting the land uses within them. Today, Kansas watershed districts face challenges in completing nearly half of the 3,000 structures proposed since 1953. Insufficient funding, burdensome policy changes, and a declining interest from local board members and landowners are key challenges boards must overcome in addition to managing rapidly aging infrastructure and dealing with projects that have exceeded their life expectancy. Research methods used for this report include content analysis of general work plans, relevant federal and state policies, and interviews with local stakeholders. In order to understand the economic, political, social and geographic impacts of watershed development, the following issues are addressed: cost-benefit ratios using monetary and non-monetary benefits, differences between federal and state funding in regards to rehabilitation and best management practices, local perceptions of watershed development, and spatial factors that exist among watershed districts. This study found that watershed projects have the potential to provide up to $115 million each year in monetary and flood damage reduction benefits in Kansas protecting over 35,000 miles of transportation routes while providing recreation opportunities and enhancing environmental conservation efforts. Political and social impacts were identified through in-person interviews with 21 local stakeholders that include landowners, board members and state representatives, representing 21 different watershed districts. Perceptions of political and social issues indicate that when government assistance is available, watershed districts are more willing to deal with increased regulations. However, a lack of financial support that has existed in Kansas watershed districts over the last eight years has contributed to a general opposition of increased federal regulations and reluctance to continue building watershed structures. Spatial factors among watershed districts illustrate the spatial and temporal differences in district development, watershed structure construction, and precipitation gradients that influence land use and ecoregions between western and eastern Kansas.

Abstract (sommario):
Watersheds are complex systems that are influenced by many factors including geomorphology, climate, soil, vegetation, and land management. Due to this complexity, a watershed assessment that evaluates both the riparian and upland areas has yet to be developed. We proposed investigating a combination of plant community composition within the greenline, upland ecological site function assessment with the Interpreting Indicators of Rangeland Health (IIRH) protocol, and stream morphological parameters. Stream parameters investigated were Rosgen?s classification method, bank erosion hazard index (BEHI) and bank height ratio (BHR). This research was conducted on five intermittent streams in southwestern North Dakota. We found that facultative wetland species offered the most protection to intermittent streambanks as a result of hydrology. When assessing the uplands it was determined that there is a positive correlation between rangeland health and riparian health. The stream parameter that showed the strongest relationship was the BEHI.

Watershed councils in Oregon have been created and developed for collaborative watershed management since the 1990s. Although a lot of research has been conducted to examine the conceptual framework and practical experience of watershed councils, there have been fewer investigations of the outreach and education strategies used by watershed councils. The goal of this study is to identify the range of outreach strategies that have been used by watershed collaboratives and discuss how these strategies relate with councils focused at the organizational level compared to those focused at the action level. OWEB grant applications provide the major source of data for examining a sample of eighteen among more than ninety watershed councils in Oregon. The study results reveal that watershed councils' outreach strategies include direct involvement and public outreach. The planning of outreach is incorporated into mission statements, organizational governance, board member representatives and recruitment, decision-making processes, meetings, community events, watershed events, invitation and tracking, and outcome measures. Action and organizational groups use similar public outreach approaches but adopt different direct involvement strategies. Action councils rely more on direct involvement from participants in the community, while organizational councils are more likely to use partnerships to achieve their involvement goals. Three themes emerged from this research. Organizational councils need to create "in-group" awareness and connectivity to their watershed communities since these councils lack a sense of place-based identification. Social networks are important for action councils' outreach and education, but organizational groups depend more on interorganizational networks. Lastly, multiple levels of public participation are realized in the implementation of outreach strategies by watershed councils in Oregon.

Abstract (sommario):
Snow accumulation in mountain headwater basins is vitally important to southern Alberta, where snowmelt supplies more than 80% of annual downstream runoff. This study evaluated two snow measurement techniques, and snow accumulation in southwestern Alberta. The SnowHydro sampler was compared with existing designs and observed to perform better under the forest canopy. A total station was evaluated for remotely measuring snow depth in avalanche terrain, but found to have accuracy limitations in low snow accumulation conditions. Field data were combined with indices of snow accumulation drivers to run classification and regression tree analysis (C&RT). Results quantified controls on accumulation over two years, and created spatial distributions of snow water equivalent across the watershed. Elevation was the dominant control between years, while canopy closure, slope angle, and aspect varied in importance between years and within seasons. Accurate representations of SWE suggest that C&RT could improve annual provincial water supply forecasts.

Abstract (sommario):
Since the uniform rainfall over the watershed is the most fundamental assumption in small watershed modelling, the limitation on watershed size should be investigated. This study defines the unit watershed size as a dimensinal criteron which is associated with the storm size, and the extent and frequency of storm exclusion ( called spatial and temporal errors). Two approaches of determining average storm cell radius were proposed. One is related with the spatial variation in storm rainfall (DSIP), while another considers both spatial variation and storm exclusion events (RVIP). Both analytical and empirical solutions are obtained and the effect of multiplestorm events is discussed. The storm radius for Walnut Gulch is determined as 4.6 miles which is close to others' results. Given storm radius, a relationship between unit watershed size and the spatial and temporal errors is developed analytically. Based on this relationship, both selection and evaluation of unit watershed size are made possible. If the error levels are known, then the proper watershed size can be selected and if the watershed size is given, then the error levels can be evaluated. By using unit watershed size, the models of small watersheds may be extended to those of large watersheds.

Spring Creek, Headwaters Robideux Creek, and Snipe Creek are sub-watersheds located within the Big Blue River Watershed, which drains to the Tuttle Creek Reservoir impoundment. This reservoir had a very high monetary investment since the beginning; unfortunately the lifespan for this marvel of engineering is declining rapidly due to high sedimentation rates. One of the programs for slowing the sedimentation process is the removal of highly erodible lands from agricultural production. This thesis work aimed to gather more knowledge on the natural riparian areas, to help the stakeholders of Kansas to improve their riparian woodland management decisions. The objective of the study was to characterize the structure and composition of natural riparian woodlands in three sub-watersheds of the Tuttle Creek Watershed. Data was collected using a representative sample design. Plot dimensions for mature tree data collection were 50ft by 30ft. For regeneration smaller, circular plots were used. Data analysis was completed with SAS 9.3. Results showed that trees per acre (TPA) differed significantly between Spring Creek and Snipe Creek, with Snipe Creek having the highest number of TPA. Quadratic mean diameter (QMD) also differed significantly in these two watersheds, with Spring Creek having the highest quadratic mean diameter. A different set of species was found in each watershed, with American elm (Ulmus americana) and hackberry (Celtis occidentalis) being found in high numbers in all areas. Regeneration data showed hackberry to be present in high numbers of both seedlings and saplings. Seedlings exhibited more species diversity than saplings. High economic value species were present in the natural riparian woodlands but in low numbers. Species of moderate economic value were predominant in terms of BA, TPA, and regeneration. Human impact on the riparian areas in the sub-watersheds was noticeable, both from livestock and forest management. Also invasive species were found in the riparian woodlands such as garlic mustard (Alliaria petiolata) and stinging nettles (Urtica diotica). Riparian areas have a great potential for improvement and management in the three sub-watersheds.

Abstract (sommario):
In many parts of the world, developed as well as developing, rivers are not gauged for continuous monitoring. Streamflow prediction at such "ungauged" river catchments requires information transfer from gauged catchments that are perceived to be hydrologically similar to them. Achieving good predictability at ungauged catchments requires an in-depth understanding of the physical and climatic controls on hydrologic similarity among catchments. This dissertation attempts to gain a better understanding of these controls through three independent research studies that use data from catchments across the continental United States. In the first study, I explore whether streamflow similarity among nearby catchments is preserved across flow conditions. Catchments located across four river basins in the northeast United States are analyzed to quantify the spatio-temporal variability in streamflows across flow percentiles. Results show that similarity in catchment stream response is dynamic and highly dependent on flow conditions. Specifically, the coefficient of variation is high at low flow percentiles and gradually reduces for higher flow percentiles. This study concludes that high variability at low flows is controlled by the dominance of high evaporative demand, whereas low variability at high flows is controlled by the dominance of precipitation input relative to evapotranspiration. In the second study, I examine whether streamflow similarity among catchments exists across a wide range of climatic and geographic regions. Data from 756 catchments across the United States is used and daily streamflow at each catchment is simulated using distance-based streamflow interpolation from neighboring catchments. With this approach, high predictability at a catchment indicates that catchments in its vicinity have similar streamflows. Results show that high predictability catchments are mainly confined to the Appalachian Mountains, the Rocky Mountains, and Cascade Mountains in the Pacific Northwest. Low predictability catchments are located mostly in the drier regions of US to the west of Mississippi river. Results suggest that streamflow similarity among nearby catchments is more likely in humid runoff-dominated regions than in dry evapotranspiration-dominated regions. In the third study, my goal is to identify what constitutes the essential information that must be transferred from gauged to ungauged catchments in order to achieve good model predictability. A simple daily time-step rainfall-runoff model is developed and implemented over 756 catchments located across the United States. Results show that the rainfall-runoff model simulates well at catchments in humid low-energy environments, most of which are located in the eastern part of the US, the Rocky Mountains, and to the west of Cascade Mountains. Within these regions, transfer of the parameter characterizing hydrograph recession provides reliable streamflow predictions at ungauged catchments, with a loss in prediction efficiency of less than 10% in most catchments. The results presented in this dissertation show that climate exerts a strong control on hydrologic similarity among catchments. The results further suggest that an understanding of the interaction between climate and topography is essential for quantifying the spatial variability in catchment hydrologic behavior at a regional scale.

Abstract (sommario):
The Watershed Evaluation of Beneficial Management Practices (WEB's) project is funded by Agriculture and Agri-Food Canada (AAFC). This study addresses the issue of non-point source agricultural pollution in the Bras d'Henri sub-watershed. It estimates the economic impact on the farm of an increased environmental constraint and the environmental and economic performance of Best Management Practices (BMPs) to satisfy this environmental constraint. The model's objective was to maximize net farm income subject to an environmental constraint, farm characteristics, and animal nutrient requirements. Results indicate that increasing the pollution emission constraint: (1) Reduces agricultural non-point source (NPS) pollution, (2) forces cropping patterns and farming practices to change, (3) reduces profit, and (4) induces average abatement cost and marginal abatement cost to increase at an increasing rate. Also, with comparable environmental constraints, farms are economically better off when the environmental constraint was set at the watershed scale as opposed to being set at the farm scale.
Le projet d'Évaluation des pratiques de gestions bénéfique à l'échelle du basin versant (EBB) est financé par Agriculture Canada (AAAC). Cette étude met l'emphase sur la problématique de pollution diffuse agricole présente dans le sous-bassin versant du Bras d'Henri. Cette étude fait l'estimation de l'impact à la ferme d'une contrainte environnementale croissante et de la performance environnementale et économique des Pratiques de Gestions Bénéfiques (PGB) pour satisfaire une contrainte environnementale. Les objectifs du model était de maximiser les revenus nets agricoles en ce conformant à une contrainte environnemental, à l'utilisation unique des champs, et au respect des besoins nutritionnels des animaux. Les résultats indiquent que la présence d'une contrainte environnementale croissante : (1) réduit l'émission de pollution diffuse agricole, (2) force les habitudes de production à changer, (3) réduit les revenus nets agricole, et (4) fait en sorte que les coûts moyens d'abattement et les coûts marginaux d'abattement augmentent et accélèrent. De plus, soumis à des contraintes environnementales similaires, les fermes sont économiquement gagnantes lorsque la contrainte environnemental est fixée à l'échelle de du bassin versant contrairement à une contrainte environnementale fixée à l'échelle de la ferme.

Abstract (sommario):
With increasing model complexity there is a pressing need for new methods that can be used to mine information from large volumes of model results and available data. This work explores strategies to identify and evaluate the causes of discrepancy between models and data related to hydrologic processes, and to increase our knowledge about watershed input-output relationships. In this context, we evaluate the performance of the abcd monthly water balance model for 764 watersheds in the conterminous United States. The work required integration of the Hydro-Climatic Data Network dataset with various kinds of spatial information, and a diagnostic approach to relating model performance with assumptions and characteristics of the basins. The diagnostic process was implemented via classification of watersheds, evaluation of hydrologic signatures and the identification of dominant processes. Knowledge acquired during this process was used to test modifications of the model for hydrologic regions where the performance was "poor".

Abstract (sommario):
Anthropogenic activity has greatly increased watershed export of bioavailable nitrogen. Escalating levels of bioavailable nitrogen can deteriorate aquatic ecosystems by promoting nuisance algae growth, depleting dissolved oxygen levels, altering biotic communities, and expediting eutrophication. Despite these potential detrimental impacts, there is notable lack of understanding of the linkages between anthropogenic nitrogen inputs and the spatial and seasonal heterogeneity of stream network concentrations and watershed nitrogen export. This dissertation research seeks to more accurately define these linkages by investigating the roles of landscape position and spatial distribution of anthropogenic nitrogen inputs on the magnitude and speciation of watershed nitrogen export and retention and how these roles vary seasonally across contrasting landscapes in a 212 km² mountainous watershed in southwest Montana. Results indicate localized inputs of anthropogenic nitrogen occurring in watershed areas with quick transport times to streams had disproportionate effects on watershed nitrogen export compared to spatially distributed or localized inputs of nitrogen to areas with longer transport times. In lower elevation alluvial streams, these effects varied seasonally and were most evident during the dormant winter season by amplified nitrate peaks, elevated dissolved organic nitrogen:dissolved organic nitrogen (DIN:DON) ratios and lower dissolved organic carbon (DOC):total dissolved nitrogen (DOC:TDN). During the summer growing season, biologic uptake of nitrogen masked anthropogenic influences on watershed nitrogen export; however, endmember mixing analysis of nitrate isotopes revealed significant anthropogenic influence during the growing season, despite low nitrate concentrations and DIN:DON ratios. In contrast, streams draining alpine environments consisting of poorly developed, shallow soils and small riparian areas exhibited yearlong elevated nitrate concentrations compared to other sites, suggesting these areas were highly nitrogen enriched. Watershed modeling revealed the majority of watershed nitrogen retention occurred in the upland environment, most likely from biological uptake or lack of hydrologic connectivity. This work has critical implications for watershed management, which include: 1) developing flexible strategies that address varying landscape characteristics and nitrogen loading patterns across a watershed, 2) avoiding clustering nitrogen loading in areas with quick travel times to surface waters, 3) seasonal monitoring to accurately gauge watershed nitrogen saturation status, and 4) incorporating spatial relationships into streamwater nitrogen models.

Low-Impact Development (LID) is a relatively new approach to stormwater management. It aims to mimic natural hydrology through increased recharge and decreased runoff. LID technologies focus on distributed treatment of stormwater, as opposed to traditional centralized management. The potential benefits include improved water quality in runoff, decreased flooding in rivers and streams, and increased baseflow critical to surface water quality. This thesis investigates two important aspects of any new stormwater management technology: the site level design and large-scale implications. A case study for site-level design is performed in the town of Acton in central Massachusetts. An LID stormwater management design is completed on a three-acre site. The design implements LID technologies, such as rain garden storage areas, pervious pavement, and curb cuts. Pre-developed, existing, and LID-designed scenarios are analyzed. A computer program called the Site Low-Impact Development Design (SLIDD) Model is developed to account for the distributed nature and unique characteristics of the LID technologies. Analysis reveals that LID is capable of not only improving the existing site hydrology, but returning a developed site to natural hydrologic conditions. The design is able to control both peak runoff rates and runoff volume. The watershed-scale implications of LID are of great importance, especially as implementation of such technologies increase. The potential benefits are analyzed using a water balance model of the Upper Nashoba Brook Watershed in Massachusetts. It is observed that LID implementation on a large scale can improve baseflow during critical summer low-flow months.
(cont.) It is also noted that LID can decrease flooding through the reduction of overland flow and interflow. The importance of using progressive stormwater management techniques like LID in the further development of the area is highlighted by an analysis of the decline of baseflow to zero during summer months with increased development. While the benefits strongly support LID, several concerns are noted. Both the decrease of ground water quality through increased recharge of contaminated stormwater and potential economic and logistic concerns of an increasing water table are potential liabilities of LID. The conditions under which LID could cause these problems are discussed, as well as potential solutions.

Abstract (sommario):
Erosion and flooding in the Cusco watershed have increased over the last 30 years due to urban growth and incorrect use of natural resources. New data for a section of the watershed were created with satellite image, spatial data, and geoprocessing software including Erdas Imagine 9.1 and ArcInfo and free information and software in the public domain on the internet. AGWA2.0 - SWAT modeling software used the data to assess the actual conditions of the study area (Model 1) including sediment yield, water yield, percolation, and stream flow. Then, two models were created by altering the conditions of the land cover/use grid: Model 2 changed the bare soil class into contour trenches, and Model 3 changed bare soil class into trees or forest. A comparison of Models 2 and 3 with the current state (Model 1) found that forestation, Model 3, would greatly decrease flooding and increase water infiltration.

Abstract (sommario):
Sprawling low density housing and retail developments characterize the growth patterns of many communities nationally. These patterns of development have been associated with impairments in ecosystem services that are critical to the functioning of social and natural systems. In response to the negative implications of these patterns, watershed initiatives are taking place across the U.S. These initiatives are characterized by participatory decision making processes involving diverse community interest groups. Studies have indicated that leadership and social capital contribute to the success of these initiatives. A qualitative assessment of community capacity for sustainable watershed management was conducted in two Lower Kaskaskia River watersheds. The study communities of Belleville and O'Fallon, Illinois are located in the eastern metropolitan region of St. Louis, MO. The primary concerns of community managers and planners are related to managing growth and its negative impacts on economic, social, and natural capitals. Six research questions drove this capacity assessment: (1) How do diverse community managers and residents define community health, (2) What role does the natural environment play in perceptions of community health, (3) What are the perceived effects of urbanization on the study communities, (4) What are community stakeholders' beliefs about the level of environmental protection within their communities, (5) What are stakeholders' perceptions of their communities' ability to solve problems and (6) What are critical indicators of community capacity to engage in sustainable watershed management. Study findings suggest that healthy natural environments are an essential element of healthy communities. Indicators of community capacity for watershed management were identified by participants. This list of indicators can be used as a tool by residents that have identified a need for a watershed initiative in their community. Key findings suggest that developing a sustainable vision, networking between groups, and leadership play important roles in the successful implementation of community based watershed initiatives.

Abstract (sommario):
There has been a growing interest and support by many state and local programs to address aquatic resource protection and restoration at a watershed level. The desire by many programs to implement watershed management programs has become more than just a need, rather a necessity to ensure suitable water resources. However, many challenges arise when developing and sustaining watershed programs. One such challenge is that watershed programs are resource intensive. These programs require significant funds to support monitoring, research, effective management, and to provide public outreach. In addition, these programs require knowledgeable and skilled water resource professionals who can implement and manage these tasks. Integrating university-knowledge and resources into the watershed effort can meet many of these challenges. Faculty, students, and in-kind university support can contribute knowledge, technical support, research funds, and personnel to aid and enhance watershed management activities. Furthermore, connecting watershed management activities with academic work can foster the development of future environmental planning, policy, and science professionals. The overall goal of this paper is to explore the integration of service-learning in higher education within watershed management activities. The concepts and benefits of service-learning are explored in this paper. An example of a watershed-based, service-learning initiative in the Stroubles Creek watershed, Virginia is presented. In addition, perspectives gathered from the Initiative's students and project coordinator (the author) on their work experience as service-learners are provided. The lessons and recommendations presented in this paper pave way to means of sustaining and enhancing service-learning program in watershed activities.
