Exhibit 25-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of October 1, 2004. This system includes the surface water resources in the Carmel River Basin, the ground water resources in the Carmel Valley Alluvial Aquifer, and Seaside Coastal Ground Water Subareas. Exhibit 25-A focuses on four factors: rainfall, runoff, storage, and steelhead.
The report is limited to the water year that began October 1, 2003 and ended September 30, 2004 (WY 2004). The rainfall and streamflow values are based on measurements recorded in the upper Carmel River Basin at San Clemente Dam. This site was selected because of its location above storage facilities and the availability of long-term rainfall and runoff records.
Water Supply Status: As shown, rainfall during WY 2004 totaled 18.2 inches, which is 85% of the long-term average. Runoff during WY 2004 totaled 36,270 acre-feet, which is 53% of average. Usable storage, which includes surface and ground water, was 26,380 acre-feet or 94% of average at the end of September. This storage equates to 70% of system capacity.
In addition, 388 adult steelhead were counted in the fish ladder at San Clemente Dam in WY 2004, which is 73% of the long-term average. In addition, 17,131 juvenile steelhead were rescued from drying reaches of the Carmel River mainstem by District staff. Additional steelhead rescues were made by Carmel River Steelhead Association (CRSA) volunteers in WY 2004.
Production Compliance: Under State Water Resources Control Board (SWRCB) Order No. WR 95-10, Cal-Am was allowed to produce no more than 11,285 acre-feet of water from the Carmel River in WY 2004. In addition, under current District water supply budgets, Cal-Am was allowed to produce a maximum of 4,000 acre-feet of water from the coastal subareas of the Seaside Ground Water Basin in WY 2004. Combined, Cal-Am was limited to 15,285 acre-feet of production in WY 2004.
For WY 2004, Cal-Am diverted 15,012 acre-feet from the Carmel River and Seaside basins for customer use. This water production is 273 acre-feet or approximately 1.8% less than the target system production specified for WY 2004. A monthly breakdown of Cal-Am’s production from the Carmel River and the coastal subareas of the Seaside Ground Water Basin for WY 2004 is included as Exhibit 25-B. Cal-Am’s production from the Carmel River Basin was reduced for diversions that were made for injection into the Seaside Basin. During WY 2004, the District injected 160 acre-feet of water into the Seaside Groundwater Basin.
