White Wolf Subbasin Technical Report

The purpose of the White Wolf Subbasin Technical Study (Study) is to support the basin boundary modification request (Request) being jointly submitted to DWR by Wheeler-Ridge Maricopa Water Storage District (WRMWSD), Arvin-Edison Water Storage District (AEWSD), and Tejon-Castac Water District (TCWD) (collectively referred to as the Districts), in accordance with the Basin Boundary Emergency Regulations. Request is a scientific request that involves the subdivision of the Kern County Subbasin of the San Joaquin Valley Groundwater Basin (DWR Basin 5-22.14) into two separate subbasins: the Kern County Subbasin and the White Wolf Subbasin (Subbasin). As shown on Figure 1, the proposed revision divides the subbasins along the White Wolf Fault (WWF), relying upon scientific evidence that demonstrates that the WWF provides a significant impediment to groundwater flow.
