An independent lake & reservoir data project
How full is your lake, right now?
Search any of 1,055 named U.S. lakes and reservoirs for its current pool elevation, how that compares to normal where the source reports it, a 90-day trend, and storage — from USGS and USACE data.
How it works
- Search a lake or state. The finder matches against all 1,055 tracked lakes as you type — no dropdown maze, no waiting for a page load.
- Open a lake. Every lake page carries its current pool elevation with datum, a %-full figure where the source provides one, a 90-day trend sparkline, storage, and a source-and-vintage stamp — no two pages share a number.
- Check the trend. The sparkline shows the last ~90 days at a glance; a plain rising, falling, or steady arrow sums it up. A missing figure always reads "not reported" — never a guess.

What this site is
Lake Level Tracker is a free, no-signup reference for U.S. lake and reservoir water levels. Search a lake or state to find its current pool elevation (with datum), how that compares to normal where the source reports a %-full figure, a 90-day trend sparkline, storage in acre-feet, and a source-and-vintage stamp linking the managing agency. It covers 1,055 named reservoirs across 45 states — 985 with a current elevation reading, 99 with a real %-of-conservation-pool-full figure, and 981 with a computed trend. Every figure traces to USGS Water Services or USACE CWMS Data — public domain, no key required. Provisional readings for reference; not for navigation or safety decisions.
Lake Level Tracker is an independent data project. Every elevation, %-full figure and trend comes from USGS Water Services or USACE CWMS Data — public domain — and the method behind each figure is documented, including a small, transparent data-quality pass that removes a handful of contaminated sensor readings before display. It exists because "how full is this lake" otherwise means digging through a per-gauge USGS page or a per-district USACE report with no national view. Read more on the methodology page.
