Map Projects by Watershed

The map below shows nonpoint source (NPS) projects by watershed. The size of the watershed displayed depends on the map scale; at the national and state level, the NPS projects are summarized by large hydroregions (2 digit HUCs), at the regional level, by subbasins (8 digit HUCs), and at the local level, by subwatershed (12 digit HUCs).

Any watershed with NPS projects will contain a red marker—hover over this marker to get project information for that watershed. For additional help, please refer to our instructions page.
