This is an independent site, not operated by or affiliated with the U.S. Army Corps of Engineers. Water level data comes from the USACE CWMS Data API; ramp status comes from the USACE Savannah District's public ramp status page, checked on a schedule and time-stamped by us. Boat ramp low-water elevations come from a USACE document revised July 13, 2021, and are approximate — see our methodology page for details.
Always inspect a ramp yourself before launching. Conditions change faster than any website.
