Lakes, Reservoirs and Ponds (Polygons): California, 2012
- California. Fisheries Programs Branch, Geological Survey (U.S.), and California. Biogeographic Data Branch
- This polygon shapefile is an update of California lake, reservoir, and pond layers as assembled by the California Department of Fish and Game (DFG). It includes many small and unnamed waterbodies in the High Sierra and California Cascades, some of which are not depicted on United States Geological Survey 7.5 arc-minute/1:24,000-scale topographic maps. Most data were captured at 1:24,000-scale or better. Waterbodies are represented as single polygons (with islands), with Latitude/Longitude coordinates of waterbody centroids and a unique numeric identifier for each. Waterbody polygons represent shorelines generally at full or near-full levels. A previous version of this dataset did not contain islands.The dataset was created for two purposes: First, to attempt to correct many inaccuracies in current GIS datasets for California waterbodies, especially regarding NAMES. Second, to provide a unique numeric ID system for the California Department of Fish and Wildlife of all digitized waterbodies in California in order to assist with fisheries and biological programs management and public fishing programs, including biological surveys, fish planting, and public fishing guides.
