C
Surface Water Use
Reporting Period
From 10/01/2021 To 09/30/2022
Surface Water Supply (AF)
Method used to determine
The value reported represents total surface water used for direct consumption and for groundwater recharge. Imported water and recycled water deliveries to recharge basins are metered and recorded daily. Storm water and urban runoff recharge volumes are measured by stage sensors in the recharge basins. Imported water, recycled water, and local surface water amounts used for direct consumption are provided by the individual parties in the Chino Basin. For parties that have service areas not entirely within the Chino Basin adjudicated boundary, the proportion of the surface water supply used for consumption inside the Chino Basin adjudicated boundary is not quantified. The portion of the reported volumes that were used for recharge, were recharged entirely within the Chino Basin adjudicated boundary.

D
Total Water Use
Reporting Period
From 10/01/2021 To 09/30/2022
Total Water Use (AF)
Method used to determine
Total water use data includes water used for direct consumption and for groundwater recharge. Data were obtained from Watermaster records, and/or collected from the parties in the Chino Basin. The total water use represents the sum of total water use by parties to the Chino Basin Judgment. Many of the Chino Basin appropriative pool parties have service areas that extend outside the Chino Basin adjudicated boundary. The proportion of the total water use for direct consumption that is used inside the Chino Basin adjudicated boundary is not quantified by Watermaster. Total water use is reported using the pre-defined categories by the DWR under the Water use met by source type below, and is apportioned as follows: Groundwater is groundwater produced from the Chino Basin and other basins for direct use; Surface water is imported State Water Project water and native surface water used for direct use; Recycled or reused water is recycled water used for direct use; and Other is water used for groundwater recharge which includes storm water and urban runoff, imported State Water Project water, and recycled water.

Change in GW Storage
Reporting Period
From 10/01/2021 To 09/30/2022
Change in storage (AF)
Method used to determine
The change in storage over the period of October 1, 2021 through September 30, 2022 was estimated using the Chino Basin groundwater model
