Groundwater Model

Estimate
60-70 %
Estimated values are based on the Scott Valley Intergrated Hydrologic Model with a 30% reduction in groundwater pumping due to local cooperative solutions (LCS) developed under the State Water Resources Control Board (SWRCB's) Drought Emergency Order for Scott Valley
Accuracy based on uncertainty in inputs and model uncertainty.

Estimate
Other
Urban groundwater extraction is estimated as 1,000 acre-feet, calculated based ond a Scott Valley population of 3,520 people (per the 2019 Basin prioritization).
Accuracy dependant on the accuracy of the population and accuracy of the estimated water use per person used to calculate urban groundwater exraction.
C Surface Water Supply
Total Surface Water Supply (AF)
26,000
Methods Used to Determine
The value is estimated using the current calibration of the soil water budget model used by the UC Davis Scott Valley Intergrated Hydrologic Model, and includes the estimtate from the soil water budget model published by Foglia et al., 2013a,b, available at http://groundwater.ucdavis.edu/Research/ScottValley/. A drought emergency curtailment order went into effect for the growing season of 2022, but is not thought to have reduced the amount of surface water use significantly compared to the full allocation of previous years.

Surface water use is not divided into water use sectors and is estimated as a total value.
E Change in Storage
Method used to calculate change in storage
The WY 2023 change in storage is calculated by the Scott Valley Integrated Hydrologic Model (SVIHM).
