Water-right points of diversion, drilled wells & construction permits, places of use, appropriation permits, diversion/measurement sites, and regulatory groundwater/management areas. Filter by basin (1–99), owner, county, water district, beneficial use, or location (bbox / near a point). Coordinates are reprojected to WGS84 for the map viewer.

Federal environmental-review (NEPA) pre-screen for siting wells, pads, pipelines, and rights-of-way. Aggregates the queryable upstream authorities — EPA ATTAINS impaired/303(d) waters, BLM National Surface Management Agency (federal land), NPS National Wild & Scenic Rivers, and EPA Sole Source Aquifers. No auth. screenLocation drops a point (or bbox) and returns every constraint at once. Built from the real source APIs, not EPA NEPAssist (whose query API is blocked). Federal-land layer is SURFACE management only — not subsurface/mineral ownership (split-estate caveat).
