Exhibit 25-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of May 1, 2015.  This system includes the surface water resources in the Carmel River Basin, the groundwater resources in the Carmel Valley Alluvial Aquifer and the Seaside Groundwater Basin.  Exhibit 25-A is for Water Year (WY) 2015 and focuses on four factors: rainfall, runoff, storage, and steelhead.  The rainfall and Streamflow values are based on measurements in the upper Carmel River Basin at San Clemente Dam. 

 

Water Supply Status:  As shown, rainfall through April 2015 totaled 1.29 inches and brings the cumulative rainfall total for WY 2015 to 15.56 inches, which is 74% of the long-term average through April.  Estimated unimpaired runoff during April 2015 totaled 1,208 acre-feet (AF) and brings the cumulative runoff total for WY 2015 to 20,630 AF, which is 33% of the long-term average through April.  Usable storage, which includes surface and groundwater, was 30,990 AF, or 97% of the long-term average through April.  This storage equates to 82% of system capacity.  In addition, 7 adult steelhead were counted in the fish ladder at San Clemente Dam through April.

 

Production Compliance:  Under State Water Resources Control Board (SWRCB) Cease and Desist Order No. 2009-0060, California American Water (Cal-Am) is allowed to produce no more than 9,945 AF of water from the Carmel River in WY 2015.  In addition, under the Seaside Basin Decision, Cal-Am is allowed to produce 2,259AF of water from the Coastal Subareas and 48 AF from the Laguna Seca Subarea of the Seaside Basin in WY 2015.  Altogether, Cal-Am is currently allowed to produce 12,196 AF from Carmel River and Seaside Coastal sources for customers in its main Monterey system and 48 AF from the Laguna Seca Subarea for customers in Ryan Ranch, Hidden Hills, and Bishop Systems (not adjusted for ASR recovery or Sand City Desalination).  For WY 2015 through April, Cal-Am has produced 5,442 AF from the Carmel River, Seaside Basin, Sand City Desalination, and ASR recovery, for customer use.  This water production is 764AF or 12.3 % less than the target specified for Cal-Am’s production from the MPWRS for WY 2015 through April.  A breakdown of Cal-Am’s production for WY 2015 through April is included as Exhibit 25-B.  Cal-Am’s production from the Carmel River Basin is reduced for diversions that are made for injection into the Seaside Basin; Cal-Am’s “native” Seaside Basin production is reduced for injected water recovery. For WY 2015 through April, 215 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 0 AF have been recovered for customer use.  Exhibit 25-C shows production breakdown from all sources for all uses.  Some of the values in this report may be revised in the future as Cal-Am finalizes their production values and monitoring data.
