Consider receiving a report on the addition of a Deep Aquifers Addendum to the Salinas Valley Water Conditions Quarterly Conditions Report and provide guidance to Staff on recommended changes.
Report
RECOMMENDATION:
It is recommended that the Monterey County Water Resources Agency Basin Management Advisory Committee:
Receive a report on the addition of a Deep Aquifers Addendum to the Salinas Valley Water Conditions Quarterly Conditions Report and provide guidance to Staff on recommended changes.
SUMMARY:
Staff has prepared a Deep Aquifers Addendum to the Salinas Valley Water Conditions Report (Quarterly Conditions Report). This addendum includes Staff's analysis and discussion of current Deep Aquifer conditions and will be updated every quarter with more information. This is being done in preparation of selecting a subset of wells to represent the Deep Aquifers in the Quarterly Conditions Report, beginning next water year.
DISCUSSION:
The Quarterly Conditions Report is produced every quarter of the water year and provides a brief overview and discussion of water conditions including precipitation, reservoir storage and groundwater level trends (Attachment 1). More than 100 wells are measured each month to monitor seasonal groundwater level fluctuations in the Salinas Valley. A subset of wells is used to generate average groundwater levels for each aquifer or subarea. Currently, the Quarterly Conditions Report does not include the Deep Aquifers.
Staff has prepared a Deep Aquifers Addendum to the Quarterly Conditions Report (Attachment 2). This addendum includes Staff's analysis and discussion of current Deep Aquifer data and will be updated every quarter. The first version includes information on the wells being considered to represent the Deep Aquifers, current groundwater levels and trends of these wells, and discussion on the vertical hydraulic gradient between the Deep and overlying aquifers. This information is being presented while Staff contin...
