Water budgets in the Cuyama Basin GSP were developed using the Cuyama Basin Water Resources Model (CBWRM) model, which is a fully integrated surface and groundwater flow model covering the Basin. The CBWRM was used to develop a historical water budget that evaluated the availability and reliability of past surface water supply deliveries, aquifer response to water supply, and demand trends relative to water year type. For the Annual Report for 2021-2022 water year, the CBWRM model was extended to include 2022 water year, utilizing updated land use, temperature, and precipitation data from those years. An update of the model, including re-calibration based on recently available data, was completed in June 2022.
An assessment of model uncertainty included in the GSP estimated an error range in overall model results of about +/- 10%.

E Change in Storage
Method used to calculate change in storage
A quantitative estimate of the annual change in groundwater storage was estimated using the Cuyama Basin Water Resources Model (CBWRM), which was extended to include the 2022 water year. The CBWRM was used to estimate the full groundwater budget in the Cuyama Basin, which consists of a single principal aquifer. The CBWRM estimates reductions in groundwater storage of 38,500 AF in WY 2022.
