2014: CASGEM prioritization: medium.
2016: Boundary modified with North American 5-021.64 subbasin
2018: Draft Basin Prioritization – high. Comments: 1) 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 YCWA 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.

Priority set high because of inter-basin water transfers.
Groundwater-related transfer “Type A” in which local groundwater is pumped to compensate for diverted surface water.
