ESA Compliance:  Consistent with the September 2001 and February 2009 Conservation Agreements between the National Marine Fisheries Service and California American Water to minimize take of listed steelhead in the Carmel River and Consistent with SWRCB WR Order Nos. 95-10, 98-04, and 2002-0002.

 

SUMMARY:  The Board will accept public comment and take action on the April through June 2010 Quarterly Water Supply Strategy and Budget for California American Water’s (CAW) Main and Laguna Seca Subarea Water Distribution Systems (WDS).  The proposed budget, which is included as Exhibits 20-A and 20-B, shows monthly production by source of supply that is required to meet projected customer demand in CAW’s Main and Laguna Seca Subarea systems, i.e.,  Ryan Ranch, Bishop, and Hidden Hills, during the April through June 2010 period.   The proposed strategy and budget is designed to maximize the long-term production potential and protect the environmental quality of the Seaside Groundwater and Carmel River Basins.

 

Exhibit 20-A shows the anticipated production by CAW’s Main system for each production source and the actual production values for the water year to date through the end of February 2010.  Please note that the anticipated production values assume that CAW annual Main system production will not exceed 14,868 acre-feet (AF), including 3,583 AF from the coastal subareas of the Seaside Groundwater Basin and 11,285 AF from the Carmel River Basin.  The total from the Carmel River Basin is consistent with State Water Resources Control Board (SWRCB) Order No. 95-10 and the total from the Seaside Groundwater Basin is consistent with the Seaside Basin adjudication decision. Both of these limits are subject to change, pending future regulatory actions.  For the purpose of this budget, it is conservatively assumed that normal inflow conditions will occur.

 

Exhibit 20-B shows the anticipated production by CAW’s Laguna Seca Subarea system for each production source and the actual production values for the water year to date through the end of February 2010.  Please note that the anticipated production values assume that CAW’s annual Laguna Seca Subarea systems’ production will not exceed 246 AF from the Laguna Seca Subarea of the Seaside Groundwater Basin.  This total is consistent with the Seaside Basin adjudication decision.

If the rainfall and runoff amounts in the Carmel River Basin are less than projected under the assumed normal-year conditions, then monthly production from the Seaside Basin may need to be increased.  Similarly, if rainfall and runoff amounts are greater than projected and streamflow in the Carmel River exceeds the instream flow requirements specified by the National Marine Fisheries Service (NMFS), additional water will be diverted by CAW for injection into the Seaside Groundwater Basin as part of the Phase 1 ASR Project.  The amount of water diverted from the Carmel River that is treated and delivered for injection will also depend on customer demand, the available production capacity of CAW’s wells in the Carmel Valley at that time, and available injection capacity of the ASR wells in the Seaside Basin  

 

RECOMMENDATION:  The Board should receive public input, close the Public Hearing, and discuss the proposed quarterly water supply budget.  District staff recommends adoption of the proposed budget.  The budget is described in greater detail in Exhibit 20-C, Quarterly Water Supply Strategy Report: April – June 2010.

 

BACKGROUND:  The Quarterly Water Supply Strategy and Budget pertains to production within CAW’s Main and Laguna Seca Subarea systems for the three-month period of April, May and June 2010.  Staff from the District, CAW, California Department of Fish and Game (CDFG), and NMFS cooperatively developed this strategy on March 11, 2010.  Based on current reservoir and Carmel Valley Alluvial Aquifer storage conditions, and the significant rainfall that has occurred to date, it was agreed that “normal” year inflows would be used to assess CAW’s operations and set monthly production targets for CAW’s systems. 

 

To meet customer demand in its main system, CAW will produce approximately 106, 0, and 0 AF of groundwater from its wells in the Upper Carmel Valley during April, May, and June 2010, respectively.  Similarly, CAW will produce approximately 1,086, 998, and 991 AF of groundwater from its wells in the Lower Carmel Valley during April, May, and June, respectively.  Of this production, it is assumed that 186 AF would be diverted from the Carmel River and injected into the Seaside Groundwater Basin in April 2010.  It is currently projected that river flow will not be sufficient in May to allow operation of ASR; the permitted diversion season ends May 31. 

 

It was also agreed that, subject to rainfall and runoff conditions in the Carmel River Basin, CAW would produce 100, 400, and 500 AF from the Coastal Subareas of the Seaside Basin, respectively, during this period.  The June production from the Coastal Subareas of the Seaside Groundwater Basin would be comprised of 275 AF of native groundwater, combined with 225 AF of storage recovered from ASR.  In addition, it was also agreed that CAW would produce 17, 24, and 27 AF of groundwater from its wells in the Laguna Seca Subarea for its customers in the Ryan Ranch, Bishop, and Hidden Hills systems during this period.  Lastly, it was agreed that CAW would not divert any water from San Clemente Reservoir through the Carmel Valley Filter Plant during this quarter.  CAW will operate its wells in the Lower Carmel Valley in a downstream-to-upstream order.  If actual inflows are more or less than projected for the budget period, the group will reconvene and adjust the diversion and release rates accordingly.

 

Rule 101, Section B of the District Rules and Regulations requires that a Public Hearing be held at the time of determination of the District water supply management strategy.  Notice of this Public Hearing has been published in The Herald.  Adoption of the quarterly water supply strategy and budget is categorically exempt from the California Environmental Quality Act (CEQA) requirements as per Article 19, Section 15301 (Class 1).  A Notice of Exemption will be filed with the Monterey County Clerk's office, pending Board action on this item.
