Exhibit 24-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of January 1, 2017.  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 24-A is for Water Year (WY) 2017 and focuses on four factors: rainfall, runoff, and storage.  The rainfall and Streamflow values are based on measurements in the upper Carmel River Basin at Sleepy Hollow Weir. 

 

Water Supply Status:  Rainfall through January 2017 totaled 11.44 inches and brings the cumulative rainfall total for WY 2017 to 18.79 inches, which is 169% of the long-term average through January.  Estimated unimpaired runoff during January 2017 totaled 68,938 acre-feet (AF) and brings the cumulative runoff total for WY 2017 to 84,288 AF, which is 433% of the long-term average through January.  Usable storage, which includes surface and groundwater, was 31,800 or 106% of the long-term average at the end of January.  This storage equates to 84% of system capacity. 

 

Production Compliance:  Under State Water Resources Control Board (SWRCB) Cease and Desist Order No. 2016-0016, California American Water (Cal-Am) is allowed to produce no more than 8,310 AF of water from the Carmel River in WY 2017.  Through January, Cal-Am has produced 2,070 AF from the Carmel River (including ASR, Table 13, and Mal Paso.)  In addition, under the Seaside Basin Decision, Cal-Am is allowed to produce 2,251AF of water from the Coastal Subareas and 48 AF from the Laguna Seca Subarea of the Seaside Basin in WY 2017.  Through January, Cal-Am has produced 974 AF from the Seaside Groundwater Basin.  Through Jannuary, 548 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 305 AF have been recovered for customer use, and 101 AF have been diverted under Table 13 water rights.  Cal-Am has produced 2,857 AF for customer use from all sources through January, which corresponds to 199 AF more than the budgeted to date for the MPWRS.  A breakdown of Cal-Am’s production for WY 2017 is included as Exhibit 24-B.  Exhibit 24-C shows production by source.  Some of the values in this report may be revised in the future as Cal-Am finalizes their production values and monitoring data.
