The Wisconsin DNR's Surface Water Data Viewer (SWDV) is an interactive map that displays primarily statewide water-related data.
River segments, lakes, and estuaries designated under Section 303(d) of the Clean Water Act in Lake Michigan Basin (MI and WI).
The HYDROMAP software generates current and water level predictions for any coastal waters around the world. HYDROMAP allows users to hindcast/forecast simulations of water levels and analyze currents and open geometry for the coastal shelf.
With a focus on the major waterways of the Chicago and Calumet region, NFWF's Chi-Cal River Fund awards grants to projects that reduce stormwater runoff with green infrastructure, enhance fish and wildlife habitat, and improve public-use opportunities.
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.
The USGS National Water Information System provides information on quantity, quality, distribution, and movement of surface water and groundwater for the United States.
The U.S. Environmental Protection Agency (US EPA) is developing e-Estuary, a decision-support system for coastal management. E-Estuary has three elements: an estuarine geo-referenced relational database, associated estuarine and watershed GIS coverages, and tools to support decision-making. A population of 300 estuaries with associated watersheds at the HUC-10 scale (16-100 ha) or larger within the conterminous U.S. has been identified for characterization of estuarine geomorphology, tidal and hydrologic regime, and land-use/land-cover of associated watersheds.
The Ohio Coastal Atlas (OCA) Map Viewer displays geospatial information about Lake Erie and its watershed to support coastal decision-makers, land management professionals, engineers, educators, interest groups, and the general public. Many of the data layers are also highlighted in the Ohio Coastal Atlas Second Edition.
The resource provides information on Ohio's nonpoint pollution control plan.
