Cuyama Valley:
Water Availability Study

Geohydrologic Framework

The Cuyama groundwater basin's geologic structure is composed of sub-basins and groundwater does not move freely between these different formations, or between different geologic regions within the Cuyama Valley. Because of the differences in geology, hydrology and water quality, there are unique conditions and issues for each subbasin, in addition to a need for a whole-basin understanding of the system.
