2018: Draft prioritization – medium. Comment: In the Ojai Valley, the water level elevation in key Well No. 04N22W05L08S was down 50.2 feet from the 2013 measurement after having been down 78.4 feet from the 2012 measurement. The Ojai Valley basin responds quickly to rainfall or the lack of rainfall, and it is not uncommon to see large drops in water level during dry periods and recovery to at or above normal levels during wet periods (see Hydrograph in Appendix B).
