EXECUTIVE SUMMARY
The Eastern Kern County
Resource Conservation District received a Local Groundwater
Assistance Fund Grant (AB 303) on behalf of the Indian
Wells Valley Cooperative Groundwater Management Group.
The purpose of the grant is to conduct groundwater
studies or to carry out groundwater monitoring and
management activities in accordance with the groundwater
management authority of the voluntary and cooperative
Groundwater Management Plan of the Indian Wells Valley
Cooperative Groundwater Management Group. Members
of the Indian Wells Valley Cooperative Groundwater
Management Group include the Eastern Kern County
Resource Conservation District, Naval Air Weapons
Station (NAWS) China Lake, Indian Wells Valley Water
District, Kern County Water Agency, City of Ridgecrest,
Bureau of Land Management, Inyokern Community Services
District, Indian Wells Valley Airport District, IMC
Global Inc., and Quist Farms.
This
report summarizes the work conducted under the AB 303
grant, including (1) a summary and interpretation of
the available data that were collected, (2) a hydrogeologic
conceptual model, (3) identification of gaps in the available
data, and (4) recommendations for future work, studies
and/or research projects. The primary objective of this
effort is to better understand the hydrodynamics, groundwater
chemistry, and groundwater availability within the Indian
Wells Valley groundwater basin.
