Exhibit 20-A shows the water
supply status for the Monterey Peninsula Water Resources System (MPWRS) as of December 1, 2016. This system includes the surface water
resources in the
Water Supply Status: Rainfall
for December 2016 totaled 3.31 inches
and brings the cumulative
rainfall total for WY 2017 to 7.35
inches, which is 108% of the
long-term average through December. Estimated unimpaired runoff during December 2016 totaled 3,841 acre-feet
(AF) and brings the cumulative runoff total for WY 2016 to 15,350 AF, which is 221%
of the long-term average through December. Usable storage, which includes surface and
groundwater, was 30,510 or 106%
of the long-term average at the end of December. This storage equates to 81% 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 December, Cal-Am has
produced 1,230 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 December,
Cal-Am has produced 749 AF from the
Seaside Groundwater Basin. Through December, 112 AF of Carmel River Basin groundwater have been diverted for Seaside
Basin injection; 305 AF have been
recovered for customer use, and 10 AF
have been diverted under Table 13 water rights.
Cal-Am has produced 2,207 AF
for customer use from all sources through December,
which corresponds to 124 AF less
than the budgeted to date for the
MPWRS. A breakdown of Cal-Am’s
production for WY 2017 is included as Exhibit 20-B as well as a comparison of the 12 month
rolling average production compared to the WY 2017 rationing trigger of 10,607
set by District Rule 160. Exhibit
20-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.
