Status of the Basin and Administration of the Judgment
underflow beneath San Timoteo Wash. East of the Noble Creek drainage, groundwater
flows to the southeast towards the City of Banning.
The groundwater system in the Beaumont Basin is replenished from multiple sources. These
include:
Infiltration of precipitation within the unlined portions of natural streams
Subsurface seepage across fault boundaries
Return flow from irrigation and individual septic systems
Artificial recharge in man-made basins (e.g. Noble Creek Recharge Facility).
Groundwater discharges from the Beaumont Basin primarily occur from:
Groundwater production
Underflow out of the basin at the downgradient margins
Rising water in San Timoteo Creek
Evapotranspiration
3.2 Production
The Beaumont Basin Watermaster is responsible for the tracking and accounting of groundwater
production by all producers named in the Judgment regardless of the amount of groundwater
produced. Other producers, not listed in the Judgment, and pumping less than 10 ac-ft /yr., also
known as minimal producers, are exempt from the provisions of the Judgment. Figure 3-3
illustrates the location of all production wells that belong to the Appropriators and Overlying
parties of the Judgment.
3.2.1 Appropriative Party Production
There are five Appropriative Producers; namely, Banning, Beaumont, the BCVWD, the SMWC,
and the YVWD. The amount that each appropriator produces in any given year, without incurring
a replenishment obligation, varies from year to year and results from a combination of:
Their share of the Operating Yield, based on the Temporary Surplus of 16,000
ac-ft/yr for all Appropriators,
Transfers from other Appropriators,
Transfers of unused production from Overlying Producers,
Water withdrawn from their storage account, and
New yield created by the Appropriator.
Monthly and annual production by well for each of the five Appropriative Parties since 2003 are
presented in a series of tables starting with Table 3-1A for CY 2003 and continuing on an annual
basis through Table 3-1K for CY 2013. These tables also include the overall Temporary Surplus
Allocation and the amount of unused production that is eligible for storage for each Appropriator.
