Minnesota Source Water Protection Reports and Geospatial Data

The EPA's DWMAPS is an online mapping tool designed to help concerned citizens and resource managers find information about drinking water in their communities and take action to protect their source water.

The Streams and Waterbodies of the United States data layer shows the location of water features throughout the United States, Puerto Rico, and U.S. Virgin Islands

The USGS National Water Information System provides information on quantity, quality, distribution, and movement of surface water and groundwater for the United States.

The USGS's Daily Streamflow Conditions dataset includes data on streamflow at 9,936 sites across the United States.

The Water Finance Clearinghouse allows communities to access information and resources for water infrastructure and services, including funding sources and reports. The Clearinghouse contains information on watershed protection and source water.

The STORET Data Warehouse is the EPA's repository of the water quality monitoring data collected by water resource management groups across the country.

The USGS Water Use Data for the Nation includes data on water use across the United States.

The NHD displays the drainage network, specifically rivers, streams, canals, lakes, ponds, coastline, dams, and streamgages in 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.
