California State Water Resources Control Board + DWR — drinking water systems + Bulletin 118 basins + stream gages. - searchDrinkingWaterSystems ⭐ ~5K SABL polygons. county UPPERCASE - searchGroundwaterBasins ⭐ ~515 DWR Bulletin 118 basin/subbasin polygons. NO county - searchStreamGages ~2.6K USGS+DWR+local. Filter hasFlow/hasStage/gageStatus upstream quirks: Multi-host — gispublic.waterboards.ca.gov (SWRCB native) for Drinking Water + StreamGages; utility.arcgis.com (DWR utility map) for Bulletin 118. SWRCB Drinking Water OWNER_TYPE_CODE has trailing space ('L ', 'P ' etc) — handler matches both forms. Bulletin 118 is published by DWR, exposed here for one-stop water context.
