INDEX TO USGS 7.5' QUADRANGLES
Basemap: Topographic Map 1:24,000 Scale (U.S. Geological Survey)
State Plane Coordinates, NAD 1983, California Zone 2, Feet
Mapped stream channel and associated alluvial depositswithin a potential stream depletion area. Wells pumping fromthese deposits are likely to result in greater and more immediate stream depletion.
Subterranean Flow
Note: Because the delineated areas on this map were basedon information readily available at the time of its development,this map does not claim to represent all of the subterraneanstreams or potential stream depletion areas that exist in the area. Site specific investigations will be needed to verify the existenceof subterranean streams or potential stream depletion areas.

Note: Some of the delineated areas on this map do not match seamlessly with the delineated areas in adjoining quads because of differences in the geologic source maps that were used.
