Notes: 1. The "other" category indicates raw water deliveries and local surface water deliveries that are managed and negotiated by Santa Clara Valley Water District for the purposes of recharging the Llagas and Coyote Valley groundwater. It also includes the City of Gilroy recycled water demand, which offsets pumping from the Llagas Subbasin. These water supplies are indicated on this table for completeness of the Llagas and Coyote Valley groundwater budgets.
