Points showing "Dams within the jurisdiction of the State of California" (Bulletin 17-93, California Department of Water Resources (DWR), Division of Safety of Dams, Sacramento). Jurisdictional Dams are defined as "artificial barriers, together with appurtenant works, which are 25 feet or more in height or have an impounding capacity of 50 acre-feet or more. Any artificial barrier not in excess of 6 feet in height, regardless of storage capacity, or that has a storage capacity not in excess of 15 acre-feet, regardless of height, is not considered jurisdictional." (DWR Bulletin 17-93). The shapefile was prepared by the California Department of Fish and Game, Inland Fisheries Division GIS Staff from a database file provided by Floyd Brooks, DWR, containing latitude/longitude coordinates and descriptive data for each dam. Updated shapefiles generated from updated copy of bull17.dbf by the by the California Department of Fish and Game, Technical Services Branch GIS Staff. There was a net increase of 10 records. Other changes or updates are not known. * Field, wallhgt was dropped.* Dams with numbers greater than 9000-000 are owned by federal agencies and are not subject to California Jurisdiction.
This shapefile was clipped for use by the Cosumnes River Watershed Project.

DATA QUALITY ASSESSMENT:
Positional accuracy has not been quantitatively determined. Assuming
accurate decimal degree latitude/longitude coordinates to 3 places, the
dam positions are compatible with 1:250K map accuracy standards. Attribute
completeness is good. Resevoir data are subject to change with hydrologic
conditions.
