Abstract/Contents

Abstract: This point 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 centroid points.
Purpose: 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. This coverage provides an accompanying center point GIS layer for the lakes layer that was assembled by the California Department of Fish and Game. This point layer is useful for representing lake locations at small (zoomed-out) scales, labeling, etc.

Supplemental information	Points derived from fields containing coordinate values within the lakes dataset. Those values were derived from initially gaining 'centroids' using ArcGIS command tools, then editing the points as needed to place in a more central location within the lake polygons.
WGS84 Cartographics	This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.
