DWR well records, searchable by address

Every Colorado well log is filed with the Colorado Division of Water Resources (DWR) well permit database. Those records are public, but they are organized by mapped location and record number — not by street address. We hold 290,365 of them and rebuild the index weekly, so you can start from an address instead.

Search DWR records by address

Enter any Colorado address and we return the wells recorded around it — wells are plotted from the coordinates DWR recorded on each permit — only about 1% are GPS-located and most are spotted from the legal land description (section or quarter-section), so positions are approximate and a well is best read as "in this area", not "at this address".

What a DWR record contains

Not every filed report carries every field — older records are thinner, and what the state captured changed over the decades. This is the real coverage across all 290,365 records, so you know what to expect before you search.

How this differs from going to DWR directly

Nothing here replaces the official record, and for a single well you already have the record number for, DWR is the place to go (dwr.state.co.us/Tools/WellPermits). What this site adds is the part that is hard from the source data:

Common questions

Where are Colorado well logs officially filed?

With DWR — the Colorado Division of Water Resources (DWR) well permit database. Every Colorado driller files a completion report there for each well drilled, and that filing is the authoritative copy of the record. The official site is dwr.state.co.us/Tools/WellPermits.

Can I search DWR by street address?

Not directly — well records are filed against a mapped location and a record number, not a mailing address, which is the single most common reason people give up on the search. That is exactly the gap this site fills: enter an address on our free lookup and we return the recorded wells around that point, wells are plotted from the coordinates DWR recorded on each permit — only about 1% are GPS-located and most are spotted from the legal land description (section or quarter-section), so positions are approximate and a well is best read as "in this area", not "at this address".

Is this the official DWR record?

No, and it is not meant to be. This is an independent index built from the data DWR publishes, rebuilt weekly. Every well we show links back to its own DWR record, so you can always open the original filed log. If our copy and the state's ever disagree, the state's is right.

How many Colorado well records are there?

Our current copy holds 290,365 records across 56 counties, with completion dates from 1850 to 2026. That is everything DWR publishes in its bulk record set as of 2026-08-14. Wells drilled before the state's filing requirement — and hand-dug or unpermitted wells — were never filed anywhere, so they are in neither copy.

Does it cost anything?

Searching by address here is free, the same as searching DWR is free. What we charge for is the compiled property report — every recorded well near one address, with the statistics and the original log links, as one printable document for a sale or a loan file. That is $29.

Every DWR record near one property, in one document

The property report pulls every recorded well near an address — depths, water levels, yields, drillers , and links to each original filed log — as one printable summary for due diligence.
