FREE PUBLIC WATER INFORMATION · EARLY PROTOTYPE
A well-th of
information.
Water questions start somewhere. Find trustworthy original sources and prepare a research prompt for your place, your question, and the evidence you need.
Explore water quality, supply, wells, drought, rivers, utilities, floods, and research.

Building the connections, carefully.
These are collection checkpoint counts, not a count of working wells or all private wells. Location records do not establish water availability, quality, or safe drilling.
Explore the national location map. Browse saved USGS location records with original sources and explicit coverage gaps. The map is a dated, incomplete snapshot, not a live feed or a complete private-well registry. The research tools below use a separate starter source catalog.
YOUR QUESTION, YOUR RESEARCH ENVIRONMENT
Prepare a useful research prompt.
Describe your area in words. This tool creates instructions you can copy into your own AI environment. It does not run a search or send your inputs to Rainfolk.
FOLLOW THE ORIGINAL
A starter library of source pointers.
Search existing catalog metadata on this page. Titles and source pointers help discovery; indexing does not verify a document's findings or its relevance to your location. Check access, reuse rights, geography, and dates at the original source.

OPEN PROJECT
Help make water information easier to find.
The open-source Rainfolk research producer is published, with Rust and Python tests and an offline site example. The national USGS location map presents a saved snapshot with incomplete coverage; it is not a live feed or a complete US well registry.

The starter catalog contains source pointers; it does not imply verified evidence for every place. Terlingua was the first case study; Rainfolk's research approach is intended for people's own places.
