SUMMARY: The Board will accept public comment and take action on the April through June 2003 Water Supply Strategy and Budget for the California-American Water Company (Cal-Am) Water Distribution System (WDS).† The proposed budget, Exhibit 10-A, is based on below normal year inflow conditions for the remainder of the Water Year 2003 (WY 2003).† Specifically, the budget utilizes inflows that are expected to be exceeded 75 percent of the time at San Clemente Dam.† The proposed strategy and budget is designed to maximize the long-term production potential, allow injection testing of surplus water from the Carmel River Basin into the Seaside Basin, and protect the environmental quality of the Seaside and Carmel Valley basins.
Exhibit 10-A shows the anticipated production by Cal-Am for each production source.† Exhibit 10-A also shows actual production values for the water year to date.† Please note that the anticipated production values shown assume an annual Cal-Am production totaling 15,285 AF, including 4,000 AF from the Seaside Basin and 11,285 AF from the Carmel River Basin.† The total from the Carmel River Basin is consistent with SWRCB Order Nos. 95-10 and 98-04.†
For the first five months of Water Year 2003, Cal-Amís production is below the SWRCB-based production target by 203 acre-feet or 3.8%.
Given that the flow below San Clemente Dam is projected to recede below 90 cfs during the April 1-15 period and below 80 cfs during the May 1-31 period, for the purpose of this budget it is assumed that no water will be diverted from the Carmel River Basin for injection into the Seaside Basin during these periods.
RECOMMENDATION: The Board should receive public input, close the Public Hearing, and discuss the proposed water supply budget.† District staff recommends adoption of the proposed budget.† The budget is described in greater detail in Exhibit 10-B, Quarterly Water Supply Strategy Report: April Ė June 2003.
BACKGROUND:† The Quarterly Water Supply Strategy and Budget pertains to production within the Cal-Am Water Distribution System for the three-month period of April, May, and June 2003.† This strategy was developed cooperatively with staff from the District, Cal-Am, NOAA† Fisheries, and the California Department of Fish and Game (CDFG).† Based on the fact that San Clemente and Los Padres Reservoirs were full and spilling on March 5, 2003, it was agreed that for the remainder of March 2003, Cal-Am's mean daily diversion through the Carmel Valley Filter Plant would be limited to 1.5 cubic feet per second (cfs), including combined production from the Russell Wells Nos. 2 and 4 and from the direct diversion at San Clemente Dam.† During April, May, and June 2003, the proposed budget allows Cal-Am a net diversion of no more than 92 AF in April, 73 AF in May and 50 AF in June, from its sources upstream of, and including, Scarlett Well No. 8.† This operation will facilitate production at minimal levels in recognition of Cal-Amís Interim Drawdown Project at San Clemente Dam and the 2001 Conservation Agreement with NOAA Fisheries, and the relatively low runoff conditions expected this spring.† The operation of Cal-Am wells in the upper Carmel Valley is based on the assumption that daily inflows will average 54 cfs during April 2003.† 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.† These adjustments will take into account flows needed for steelhead emigration and egg incubation.
Streamflow is expected to decline below 40 cfs at the MPWMD gaging station at Highway One Bridge, sometime in April.† As a consequence, the group agreed to increase production from Cal-Am wells in the coastal subareas of the Seaside Groundwater Basin during April, May and June 2003, subject to increases in streamflow.† This change is consistent with requirements in SWRCB Order 98-04, requiring that Cal-Am minimize production from the Seaside Basin when Carmel River flow exceeds 40 cfs at Highway One.
As part of the quarterly water supply strategy and budget discussions, Cal-Am noted that California Department of Health Services (DHS) has required that all use of Cal-Amís San Carlos production well in the lower Carmel Valley be discontinued until Cal-Am has implemented an approved plan of action to ensure that all water from the San Carlos well meets the Surface Water Treatment Rule.† Further, Cal-Am indicated that they are unable to provide this type of treatment at this time and, consequently, have taken the San Carlos well out of service.† When operating, the San Carlos well can produce approximately 1,000 gallons per minute (gpm) or 4.45 acre-feet per day.† Loss of this production capacity will constrain Cal-Amís ability to meet system demands during peak periods and increase the extent of drying river channel and associated risk of stranding juvenile steelhead in the lower Carmel River.
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.
