Maps or resources from Geographic Information Systems (GIS) are essential to making effective use of watershed information. Yuba Shed includes these dynamic mapping projects:

   Streamflow Gages in the Yuba Watershed

This map provides a portal to streamflow information in the Yuba watershed. For more detailed information on gages associated with the hydropower projects in the Yuba River watershed owned by NID and PG&E, see the YBDS Dreamflows Project.


UC Davis provides KML downloads for the Yuba River Watershed and some summary watershed statistics. The site also provides a Google Map tool with spatial data layers concerning hydrographic features, including dams, powerhouses and conveyances. Additional KMLs for the Yuba River Watershed (e.g. roads, population density, legacy mines) is available from the UC Davis Watershed Support Group. Future versions of Yuba Shed will consolidate these types of resources.

Several organizations, such as Nevada County or Tahoe National Forest, maintain GIS for portions of the Yuba River watershed. SYRCL maintains a GIS for the Yuba River watershed which includes data from all available sources, and issues custom watershed maps as needed. For examples, see Yuba Watershed Map Atlas.
