Exhibit 21-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of September 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 21-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 August 2017 totaled 0.00 inches and brings the cumulative rainfall total for WY 2017 to 32.22 inches, which is 153% of the long-term average through August.  Estimated unimpaired runoff during July totaled 920 acre-feet (AF) and brings the cumulative runoff total for WY 2017 to 195,579 AF, which is 292% of the long-term average through July.  Usable storage for the MRWPRS was 30,410 acre-feet, which is 105% of average through August, and equates to 81% percent 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 August, using the CDO accounting method, Cal-Am has produced 5,869 AF from the Carmel River (including ASR capped at 600 AF, 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 August, Cal-Am has produced 1,939 AF from the Seaside Groundwater Basin.  Through August, 2,345 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 1,188 AF have been recovered for customer use, and 491 AF have been diverted under Table 13 water rights.  Cal-Am has produced 8,702 AF for customer use from all sources through August.  The 12 month rolling average of production is 10,005 AF, is below the rationing threshold of 10,609 AF.  A breakdown of Cal-Am’s production for WY 2017 is included as Exhibit 21-B.  Exhibit 21-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.
