The Great Lakes Water Quality Agreement (GLWQA), signed by Canada and the United States, is a commitment to protect the waters of the Great Lakes. It was most recently updated in 2012. Annex 4 was formed to manage phosphorus concentrations and loadings (and other nutrients if warranted) in the Great Lakes.
The United States Department of Agriculture - Agricultural Research Service (USDA-ARS) developed this computer-generated model to estimate the nutrient loads coming from sub-basins in areas with insufficient water quality monitoring data. The model has been run in areas like the Lower Maumee where there is enough water quality monitoring data to calibrate the program.
MAEP is a voluntary verification program that helps farmers reduce environmental impacts from their operations by providing technical assistance for the design and implementation of conservation plans. The Overview describes several other indicators of success that speak to water quality outcomes and farmer engagement including participation in training events and tons of sediment and phosphorus loading reduced.
The PA DEP open data portal provides GIS data for drinking water, water quality, and other resources.
The NERRS Science Collaborative is a network of network of 28 coastal reserves designated to protect and study estuarine systems around the country. The Science Collaborative fosters the development and application of research that addresses coastal management problems important to the reserves. The Science Collaborative administers annual requests for proposals to identify, fund, and foster science-based projects that address coastal management problems that important to the coastal reserves.
To date, the program has funded collaborative projects addressing the following:
The Illinois-Indiana Sea Grant (IISG) funds research projects related to the use, development, and conservation of Lake Michigan coastal resources in Illinois and Indiana.
The Fund for Lake Michigan's grant making is focused on projects in southeastern Wisconsin that will:
The Western Lake Erie Nutrient Source Inventory (NSI) is an interactive map showing sources of nutrients in the Western Lake Erie watershed. The NSI looks at urban and rural sources of runoff throughout the Western Lake Erie Basin that are contributing to harmful algal blooms.
nowCOAST is a GIS-based web mapping portal that displays near real-time observations, analyses, tide predictions, model guidance, watches/warnings, and forecasts for the coastal United States. nowCOAST is designed to be a planning aid to assist recreational and commercial mariners, coastal managers, HAZMAT responders, coastal ocean modelers, and marine educators to discover and display real-time information for their particular needs and geographic area of interest.
The Estuary Data Mapper (EDM) is a free, interactive, downloadable application under development at the US EPA that allows users to quickly and easily retrieve, view, and save subsets of online US coastal estuary-related data. It is intended to help researchers, managers, and decision-makers find and map data relevant to coastal estuary systems.
Overview The Global Surface Water Explorer maps the location and temporal distribution of water surfaces at the global scale for 1984-2015 and provides statistics on the extent and change of those water surfaces. Users can view the data on an interactive map or download datasets.
