2014: CASGEM basin prioritization – medium. Comment: Strong surface water-groundwater interaction with Feather and Yuba River. GW Use based on B118‐03 and 2005 Butte County Inventory data.
2018: Draft basin priority – high. Groundwater level comments: CASGEM/WDL/GWIDS Stable hydrographs. Source: DWR 2) Began using surface water in 1981 to mitigate previous declining groundwater levels; gwls have now recovered. Partly in response to this water table decline, the Yuba County Water Agency began to provide Yuba River water to Brophy Water District and South Yuba Water District in 1983. Monitoring indicates groundwater levels have recovered since the early 1980s. Currently both the Yuba North Subbasin and the Yuba South Subbasin are in good health.

Basin priority set high because of out-of-basin water transfers.
Per 2018 draft basin prioritization: Groundwater-related transfer “Type A” in which local groundwater is pumped to allow for diversion of surface water.
