    <abstract lang="eng" displayLabel="Abstract">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.</abstract>
    <abstract lang="eng" displayLabel="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.</abstract>

    <note displayLabel="Supplemental information">This dataset represents a combination of 1:24,000-scale or better GIS datasets considered the best currently available. The initial sources come from DFG's fisheries programs, some of which included many Sierra Nevada lakes and ponds not represented on existing USGS maps and/or not known to exist in digitized format elsewhere. Unique ID's in the field DFGLAKEID reflect the LAKE_ID in FPB_Lakes shapefile in about 22,400 cases. Many errors (attribute and spatial) existed in all the contributing datasets, and many (but not all) have been remedied here. Lake name errors were addressed to the greatest extent, spatial representation errors to a lesser extent. USGS National Hydrography Dataset (NHD) High Resolution 'waterbody' polygons were used to replace some existing polygons. It was not used exclusively however, due in part to existing errors within the NHD datasets to date, the lack of completeness for CA and the lack of time on the editors end to incorporate NHD in cases where NHD polygon representation is better than what exists here. It is the intent that NHD polygons will be incorporated more as they get updated.</note>
