Exhibit 17-A shows the water supply status for the Monterey Peninsula Water Resources System (MPWRS) as of March 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 17-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 February 2017 totaled 9.27 inches and brings the cumulative rainfall total for WY 2017 to 28.06 inches, which is 182% of the long-term average through February.  Estimated unimpaired runoff during February  totaled 75,173 acre-feet (AF) and brings the cumulative runoff total for WY 2017 to 159,461 AF, which is 444% of the long-term average through February.  Usable storage, which includes surface and groundwater, was 32,780 or 106% of the long-term average at the end of February.  This storage equates to 87% 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 February using the CDO accounting method, Cal-Am has produced 2,557 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 February, Cal-Am has produced 1,034 AF from the Seaside Groundwater Basin.  Through February, 953 AF of Carmel River Basin groundwater have been diverted for Seaside Basin injection; 305 AF have been recovered for customer use, and 192 AF have been diverted under Table 13 water rights.  Cal-Am has produced 4,267 AF for customer use from all sources through February, which corresponds to 844 AF more than the budgeted to date for the MPWRS.  A breakdown of Cal-Am’s production for WY 2017 is included as Exhibit 17-B.  Exhibit 17-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.
