3.4 Water Transfers and Adjustments of Rights

Section 7 of the Watermaster Rules and Regulations, as amended in September 2008,
provides for the adjustment of rights by and between Appropriators and Overlying Parties. This
section indicates that Watermaster shall maintain an accounting for all transfers and include
said transfers in the Annual Report or other relevant document. There are three types of
transfers that Watermaster accounts for:

9 Transfer of water rights and/or water in storage between Appropriator

9 Transfer of water rights from Overlying producers to an Appropriator in exchange for
water service, and

9 Allocation of unused Overlying Water to the Appropriator Parties based on their share
of the Operating Safe Yield.

According to Part VI, Administration, Paragraph 5Y of the Judgment, the Safe Yield of the
Beaumont Basin shall be re-determined at least every 10 years after the date of entry of the
Judgment, February 4, 2004. In 2015 the Safe Yield of the Beaumont Basin was re-
determined and estimated at 6,700 ac-ft/yr. This amount represents a 22.54 percent reduction
from the previous estimate of 8,650 ac-ft/yr. Table 3-6 presents the initial and revised
production rights from individual Overlying producers and compares them against actual
groundwater production during the 2014-18 five-year period for each user. Annual average
groundwater production during this period for all Overlying producers combined was estimated
at 2,173.3 ac-ft/yr; representing approximately 32.4 percent of the revised Safe Yield.
Individually, none of the Overlying producers produced more than their allowable production
rights during this five-year period; California Oak Valley Golf and Resort LLC averaged the
highest percentage of their respective allocation at 84.9 percent followed by Plantation by the
Lake at 83.9 percent and Sharondale Mesa Owner Association at 71.1 percent. Tukwet
Canyon Golf Club followed at an average of 59.7 percent of their Overlying right.

3.4.1 Transfers between Appropriators

According to Section 7.3 of the Rules and Regulations, an Appropriator may transfer all or a
portion of its production right or water in storage that exceeds its supply needs to another
Appropriator.

In January 2008, the SMWC and the BCVWD entered into a transfer agreement that allows
BCVWD the option to purchase all water that SMWC determines to be available for transfer
from their storage account. As part of the agreement, each year the SMWC estimates the
amount of water available for transfer and offers it to the BCVWD for purchase prior to offering
it to other Appropriators. Since the beginning of the agreement, SMWC has transferred 9,500
ac-ft of water to BCVWD with 3,500 ac-ft transferred in CY 2011. SMWC also transferred
1,500 ac-ft of water to Banning in CY 2007. The purchase agreements and transfers between
these agencies are on file with Watermaster.

Water transfers between Appropriators were not reported during CY 2018.
