Nonpoint Source (NPS) Watershed Projects : Interactive Map and Reporting

      NPS pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. NPS pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters.

      This map presents all U.S. States and Territories that contain nonpoint source (NPS) watershed restoration projects. The data being represented in this mapping application are being pulled directly from the Section 319 Grants Reporting and Tracking System (GRTS). The NPS projects are summarized by state as well as various levels of watersheds: subbasins (8-digit HUCs) and subwatersheds (12-digit HUCs) at the local level. You can click on any U.S. State or Territory to drill deeper into these watersheds to find NPS projects, or you may selectively search by HUC12 code, HUC8 code, or by subwatershed name as search filters to the right of the map (as well as incorporating other data filters). For more information on the interactive map and its reporting tools, please expand the Instructions and Explanation of Features section below.
