The river was at 2.87 feet. Signed.
Parametric flood payouts, dam and flood-operations litigation, and moratorium or easement disputes all turn on one number: what the gauge read at a moment. Real-time gauge data is provisional by design, and by the time the dispute lands, the operational feed has often been revised or overwritten by the agency's own quality control. This page issues a signed, independently re-verifiable receipt of the reading the USGS gauge network reported for your station right now. A timestamped record that fixes the number when it mattered.
A signed receipt for your gauge, right now.
Enter a USGS station id. Dynamic Feed records the station's current gage height and discharge as observed evidence and returns one Ed25519-signed Decision Receipt produced by /v1/answer. Nothing is mocked and nothing is stored about you. Australian flood watch and UK river levels are covered by other live feeds on the platform.

Flood disputes are decided on one number.
A parametric flood policy pays when the named gauge crosses the named threshold. A flood-operations case asks what the operator knew the river was doing when the gates were opened. A building moratorium or easement fight asks whether the water actually reached the line. In every one of these, the decisive fact is a gauge reading at a moment, and the operational feed that reading came from is provisional: the agency revises it, sometimes substantially, during later quality control. A contemporaneous record from a neutral witness, signed at the moment, carrying its source and observation time, and verifiable years later against a published key, fixes what the network was reporting when the decision was made or the trigger was tested. Our records work against us just as well as they work for you: anyone can re-check them, including the other side.
Evidence, not a settlement source.
Dynamic Feed is a neutral witness, not a settlement agent, regulator or adviser. This receipt is a record of what the named public gauge network (USGS NWIS) reported at that moment; provisional readings are subject to the agency's own revision, which is exactly why a timestamped record of the provisional value matters. It is not the contractual settlement source unless the contract names it, not a flood-risk assessment, and not an operations recommendation. Advisory evidence, tamper-evident not tamper-proof, zero personal data, and not legal advice.
