Blandon explained the 25-year historical precipitation chart from 1994-
2018, showing an average of 14.3 inches. Looking at the last eight
years, average precipitation is below the 25-year average. This is
almost 3 inches lower than the 100-year average of 17 inches. He said
he hopes this year the curve will begin bending to the positive side.

He pointed out the total 2018 production for each appropriator, totaling
more than 15,000 acre-feet. This is the third highest production year
since inception of the judgment, and about 2,000 acre-feet higher than
the 2014 – 2018 five-year average.

Mr. Blandon pointed out that Oak Valley Golf and Resort used 85 percent
of their overlying water rights, followed by Plantation on the Lake at 85
percent over the last five years. None of the large producers are close
to their limits. Between 2014 and 2018, production averaged 2,100 ace-
feet, or approximately 32 percent of overlying right. Numbers reported
by Plantation on the Lake in previous years were inaccurate. The 2018
report shows the corrected data.

Engineer Blandon drew attention to the comparison of annual
production by overlying users and appropriators. He pointed out
significant changes in 2014 as a result of the reevaluation of the basin
safe yield, and in 2018 due to the transfer of overlying rights from Oak
Valley to YVWD.

For recharge, Blandon noted, in 2018 the City of Banning spread 600
acre-feet, and BCVWD spread over 12,000 acre-feet. Overall, since the
inception of the judgment, close to 98,000 acre-feet has been
recharged to the basin, he stated.

Blandon explained the current status of water rights and pointed out
that 180.4 acre-feet of overlying rights was transferred to appropriative
rights of YVWD under Resolution 2017-02.

Engineer Blandon explained a chart showing the 6,365 acre-feet of
under-production of 2013 is being transferred to 2018 and divided
among the appropriators. Blandon gave a review of storage account
balances, increasing by 4,140 acre-feet in 2018.

Wastewater discharges continue to increase as the area continues to
develop, Blandon explained.

Mr. Jaggers provided a handout with a downward revision of some of
the numbers related to BCWVD’s storage account and production. Mr.
Jaggers detailed some additional numeral discrepancies.

He pointed to the overlyer transfer to appropriator and said he believes
there is still a struggle with how that vehicle moves forward in time.
