DWR reviewed and found “deficiencies” in the Paso Robles Groundwater Basin and Cuyama Valley Groundwater Basin sustainability plans—declining to give final approval to either.

In separate letters about the basins, DWR identified issues ranging from a lack of discussion about impacts to shallow and domestic wells, to a lack of planning for surface waters, like creeks and rivers. Six points of deficiencies were listed in all—two for Paso and four for Cuyama.
