2021-2022 West False River Emergency Drought Barrier water quality, flow, and fish monitoring

To manage the critically low 2021 water supply for beneficial uses, DWR installed the temporary emergency drought barrier (EDB) on West False River in the Sacramento–San Joaquin Delta (Delta), approximately 5 miles south of Rio Vista, California, in Contra Costa County in June 2021. To monitor the effectiveness and impacts of the EBD, a monitoring program was initiated to track changes in hydrodynamics, water quality, fish, harmful algal blooms, and aquatic weeds in the vicinity of the EDB. This data set includes all data collected as part of that monitoring program and subsets of ongoing monitoring programs that were used in the 2021 effectiveness report for the EDB.
