Rural residential groundwater extraction is estimated based on California Water Service Company's 2020 Urban Water Management Plan 2020 usage of an average per capita water use of 181 gallons per capita per day. Population data from the 2020 census was coupled with parcel data to identify total population not serviced by municipal supplies.
Uncertainties are from population estimates and gallon per capita per day estimates
C Surface Water Supply
Total Surface Water Supply (AF)
22,400
Methods Used to Determine
Diversions for local supplies are estimated based on historic State Water Resource Control Board eWRIMS (Electronic Water Rights Information Management System) data for total diversions. Surface water delivery estimates are based on historic deliveries in the area that have occurred in dry and critical years.

D Total Water Use
Total Water Use (AF)
56,900
Methods Used to Determine
Methods used are a combination of estimates based on land use and population/ per capita water use, metered municipal water use, and estimates based on historic water rights data for dry and critical years.

E Change in Storage
Method used to calculate change in storage
Change in groundwater storage was estimated based on change in measured spring-to-spring groundwater levels at each RMS well, multiplied by the area of a Thiessen polygon surrounding that RMS well (defining a representative area for each RMS well) and a representative storage coefficient of 0.1 for the principal aquifer.
