Texas Watershed Viewer
The Texas Watershed Viewer allows users to identify local watersheds, sub watersheds, river basins, and river sub basins throughout the State of Texas.
To find your watershed and river basin, simply type your address into the search bar and press enter. The map will zoom into the address. From here, click anywhere on the map and the name of the sub watershed will appear. If you click the next arrow on the feature label, the name of the watershed will appear. If you click the next arrow again, the name of the river sub basin will appear followed by the larger river basin. Feel free to explore this tool.
