Description: In order to assess the effect of this increased recharge on groundwater quality, DWR and State Water Resources Control Board staff selected groundwater wells in areas near inundated land (areas of standing water) that had historical (and continuing) groundwater quality information hosted on the Groundwater Ambient Monitoring and Assessment (GAMA) Groundwater Information System (GIS). All wells in the Sacramento and San Joaquin Valleys were initially considered for this assessment. Wells were filtered based on the amount of historical water quality data, the most recent sampling, and proximity to inundated areas. This feature layer includes the mean monthly precipitation by county in CA for March 2023, sourced from the NOAA Climate at a Glance County Mapping webpage. It is used in the web map that serves map actions in The Atmospheric Rivers of 2023 and California's Groundwater story map.
