Click on any state to zoom to the state’s HUC8 watersheds. Then select a watershed to view its subwatershed name, HUC code, and the total number of projects that are present which updates automatically to the right of the map. The deeper the shade of blue a State or Territory has, and the deeper the shade of green a watershed has, the more NPS projects are present there. A bright yellow border will appear on a selected HUC8 or HUC12. A State/Territory or watershed with no color means that no NPS projects are present there. Click on the “Show Reports Below” box to the right of the map to find the interactive reports available for the selected NPS Projects on the map.

To the right of the map, there are two query tools seen as tabs, Geographic Area of Interest and Data Filters:

Geographic Area of Interest: Under this tab there are three search methods as well as shortcut buttons which will redirect you to various geographic areas of the U.S. and its Territories including the Conterminous United States (CONUS), Alaska, Hawaii, Puerto Rico, the Virgin Islands, Guam, American Samoa, and the Marianas. You can reset the map filters and report template results by clicking on any of the Geographic Areas of Interest buttons. Manually refreshing the page will not reset your filters.

Data Filters: Under this tab, you can filter projects by Status (Current, Historical, or ALL) the date range for Project Appropriation Year (filterable range is set at 2000-current year), and a checkbox filter to show Watershed Protection Projects only (a determinant of whether 51% or more of a project's budget was used to protect unimpaired or high-quality waterbodies). There is also the option to include statewide projects that are not associated with specific watersheds (commonly seen in support for NPS staff and program management, for example).

The definition of a Current or Historical project is as follows:

Just below the map window is the Project Report section which appears when the “Show Reports Below” checkbox is selected on the right side of the page. The reports available in the dropdown menu were prepared using key predefined fields. Each report selected will create a new report with the given filters you've set in the query section above. Please note that reports may include statewide projects as well as projects not associated with specific watersheds (commonly seen in support for NPS staff and program management, for example). Lastly, you can download each report created by simply clicking on "Download" (all downloaded reports will always be in .CSV format).

All 319-funded activities are entered into GRTS as a ‘project.’ This includes actual watershed projects as well as statewide ‘projects’ that more broadly support the NPS program such as through staffing, planning, and program management. This mapper is primarily useful for displaying watershed projects that are entered into GRTS. However, there is also the option to include in your search the number of ‘statewide’ projects entered in GRTS. These 'statewide' projects will not show on the map itself once watersheds are visible; however, data for these projects will still appear in the reports by state.

When a watershed name is hyperlinked in this application you can click to find more watershed details from the EPA application “How’s My Waterway”. How's My Waterway was designed to provide the general public with information about the condition of their local waters based on data that states, federal, tribal, local agencies and others have provided to EPA. Water quality information is displayed on 3 scales in How’s My Waterway; community, state and national.
