Rural residential groundwater extraction is estimated based on City of Red Bluff?s 2020 Urban Water Management Plan 2020 usage of an average per capita water use of 253 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)
9,000
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)
27,000
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 of groundwater levels from Spring 2022 to Spring 2023 at wells screened in the Upper Aquifer were interpolated to estimate the groundwater elevation change in areas where sufficient data were available. Estimated elevation change was multiplied by a spatially variable aquifer storage coefficient available from the Tehama Integrated Hydrogeological Model (Tehama County GSA, 2022) to estimate the groundwater storage change volume in the Upper Aquifer. The spatial extent of this estimate was limited to areas where measured groundwater levels were available. Therefore, an area-weighted adjustment was applied to the estimated storage to estimate the subbasin-wide change in storage. Sufficient groundwater level data were not available to interpolate water level changes in the Lower Aquifer. Therefore, the Lower Aquifer storage change was estimated using the Upper Aquifer storage change and historical ratio of storage changes in the two aquifers for critical years. The summation of the changes in the Upper and Lower Aquifers provides the total groundwater storage change in the Subbasin.
