Exhibit 24-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of April 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 March 2017 totaled 2.17 inches and brings the cumulative rainfall total for WY 2017 to 30.23 inches, which is 162% of the long-term average through March.  Estimated unimpaired runoff during March totaled 20,383 acre-feet (AF) and brings the cumulative runoff total for WY 2017 to 169,585 AF, which is 325% of the long-term average through March.  Usable storage, which includes surface and groundwater, was 32,170 or 100% of the long-term average at the end of March.  This storage equates to 85% of system capacity. 

 

Production Compliance:  Under State Water Resources Control Board (SWRCB) Cease and Desist Order No. 2016-0016 (CDO), 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 March, using the CDO accounting method, Cal-Am has produced 3,072 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 March, Cal-Am has produced 1,172 AF from the Seaside Groundwater Basin.  Through March, 1,510 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 305 AF have been recovered for customer use, and 293 AF have been diverted under Table 13 water rights.  Cal-Am has produced 4,778 AF for customer use from all sources through March.  The 12 month rolling average of production is 9,743 AF, which is below the rationing threshold of 10,609 AF.  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.
