SUMMARY: In
addition to the Aquifer Storage and Recovery (ASR) expansion opportunities that
the Monterey Peninsula Water Management District (MPWMD or District) has been
pursuing in the Seaside Groundwater Basin, interest has also been expressed
through the MPWMD board's Water Supply Planning Committee to investigate
possible use of ASR technology at other locations. In particular, development of an ASR project
within the Carmel River Watershed in the Tularcitos Creek Basin has been
identified as a potential supplemental water supply option for the MPWMD
area. The project concept would be to
divert Carmel River flows during high-flow winter periods to underground aquifer
storage in an area of the Tularcitos Basin, for subsequent recovery and use
during summer or extended dry periods.
Recovery concepts include extraction and delivery directly to the Cal-Am
distribution system and/or delivery via summertime surface flow releases
providing streamflow enhancement.
The area of interest in the Tularcitos Basin is outside of the MPWMD
boundaries and accordingly, there is little technical information currently
available. The initial effort envisioned
under this item would include review of existing data sources, compilation of
existing well and streamflow records, creation of a database to support the
investigation, and development of preliminary hydrogeologic maps and figures.
RECOMMENDATION: District
staff recommends that the Board authorize expenditures up to $20,000 for
development of reconnaissance-level technical information regarding the Tularcitos
Basin, to support the planned feasibility analysis of a potential future ASR
project in this area. This item has been
discussed at several recent meetings of the District board’s Water Supply
Planning Committee. District staff will
continue with preparation of a Work Plan for this ASR expansion concept that
will be reviewed with the Water Supply Planning Committee if this item is
approved along with the Consent Calendar.
BACKGROUND: The
MPWMD currently holds a water right issued by the State Water Resources Control
Board (Permit 20808B) that could be the basis for the additional water rights that
would be needed for potential future ASR expansion in the Tularcitos
Basin. The work envisioned under this
item would compile preliminary technical data in support of a full feasibility
analysis of this project concept.
Existing reports and available records will be compiled to develop a
better reconnaissance-level understanding of this project. Assuming the results from this preliminary
phase of work are favorable, planned future steps would include more detailed
and specific ASR project concepts, coordination with property owners and
resource management agencies, and site-specific pilot investigations.
IMPACT ON STAFF/RESOURCES:
Planning, design, construction and operation of potential water-supply
augmentation projects are ongoing significant staff commitments, as reflected
in the District’s Strategic Plan and annual budgets. Funds for the proposed work are in the MPWMD
FY 2012-13 budget under Line Item 1-7-1 (ASR Expansion Study).
