  3. The County of Los Angeles and Los Angeles County Waterworks District No. 40, Antelope Valley, will serve as the GSA for this "basin" until such time as the CASGEM priority is determined for the revised basin boundary. It is possible that the priority will drop from high to low or very low as this area was excluded from the Antelope Valley Basin Adjudication and does not support significant groundwater use.
