Western water rights, 17 states on one map
2.1M+ adjudicated water rights across 17 western states, on one map.
All 2.1 million western water rights we can source sit in a single queryable schema — priority date, flow rate, beneficial use, source type and owner of record. Until now that record lived in seventeen separate state systems in seventeen formats, and pricing a portfolio meant weeks of clerk work.

Why Water Rights matters
In the prior-appropriation West, the water does not belong to the land — it belongs to whoever filed first. A junior right on a good parcel is worth a fraction of a senior right on a mediocre one, and in a dry year it is worth nothing at all. Priority date is the price. Until now that field lived in seventeen separate state systems, in seventeen formats, and pricing a portfolio meant weeks of clerk work.
Questions Water Rights answers
- Who owns the water within five miles of this parcel?
- How senior is this right relative to everything else in the basin?
- Which rights in this county are cancelled or abandoned and might be re-appropriated?
- What is the total permitted diversion upstream of my intake?
- Which owners hold more than one right, and where else do they hold them?
What is in the Water Rights data
Coverage: 17 western states — AZ, CA, CO, ID, KS, MT, ND, NE, NM, NV, OK, OR, SD, TX, UT, WA, WY. Source dataset: State water agency filings, normalized.
| Field | What it tells you |
|---|---|
| Priority date | The seniority date that decides who gets water in a short year. The single most valuable field in the record. |
| Flow rate (CFS) | Diversion rate in cubic feet per second, normalized from the units each state files in. |
| Beneficial use | Irrigation, municipal, industrial, mining, domestic, livestock, recreation or environmental. |
| Water source type | Surface water or groundwater — a different regulatory regime in most states. |
| Legal status | Active, perfected, claimed, cancelled or abandoned. |
| Owner of record | The name on the filing, searchable and indexed for related-rights lookups. |
| County and basin | Backfilled from point-of-diversion geometry where the state filing omits it. |
| POD / POU geometry | Point of diversion and place of use, where the source publishes both. |
How we serve Water Rights
Records land in Postgres with PostGIS geometry, indexed with trigram GIN indexes on owner, native ID and county so full-text search over 2.1M rows returns in well under a second. The map reads viewport-scoped vector tiles rather than the full table, so panning stays interactive at every zoom. Free accounts see the layer capped at 100 results; paid plans lift the cap by rung.
