About

California SWRCB and DWR water connector, multi-host (probed 2026-05-02). SWRCB is native at the agency host (Drinking Water and StreamGages); the DWR utility map is at the agency host (Bulletin 118 Groundwater Basins). 3 services via 4 methods: searchDrinkingWaterSystems (~4,991 SABL Drinking Water System Area polygons; BOUNDARY_TYPE Water Service Area=4963/Jurisdictional=28; FEDERAL_CLASSIFICATION COMMUNITY=2786/TRANSIENT NON-COMMUNITY=1275/NON-TRANSIENT NON-COMMUNITY=849/NON-PUBLIC=81; OWNER_TYPE_CODE P/L/F/S/M with a trailing space; ACTIVITY_STATUS_CD always 'A '; COUNTY UPPERCASE) ⭐; searchGroundwaterBasins (~515 DWR Bulletin 118 basin and subbasin polygons; Region_Office SRO 227/NRO 129/NCRO 82/SCRO 77; no county column on the layer, which the handler surfaces in notes) ⭐; searchStreamGages (~2,597 gages from USGS=2078, DWR=181, OTHER=124, PG&E=25, USACE=20, USBR=20, CDFW=others; gage_status Active-High Quality/Active-Limited Use/Inactive/Underwater/Infrastructure_Eliminate/Not_a_Gage; sitestatus Active=1089/Inactive=1508; Y/N flags for stage/flow/watqual/temp; no county column); and getServiceInfo. Upstream quirks: COUNTY is UPPERCASE on Drinking Water; OWNER_TYPE_CODE has a trailing space, so the handler matches both 'L' and 'L '. StreamGages caps at 1000 per page server-side. Bulletin 118 is published by DWR, not SWRCB, but is exposed under this connector for one-stop water context.
