About Stones River at Donelson

This gauge sits on Stones River at Donelson, Tennessee, immediately below J. Percy Priest Lake. Flow here is controlled by releases from the dam, so it can change by hundreds of CFS within an hour with no rain anywhere in the basin — check it before you go, not the day before.

Raw CFS means little on its own, so every reading on this page is shown against the USGS median for the same calendar day — 172 CFS for late July, from 13 years of record.

Because the National Weather Service also operates a forecast point here, the page carries the official flood-category ladder and the NWS's own stage-by-stage impact statements.
