About Lake Level Tracker
Lake Level Tracker is an independent data project that turns public USGS and USACE lake-level data into a fast, free reference. Every elevation, %-full figure and trend traces to a named federal source, the method behind each number is documented, and nothing on the site is sponsored or pay-to-rank. It exists because this information otherwise lives siloed across individual USGS gauge pages and per-district USACE reports, with no national view of "how full is this lake right now."
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, 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 and 99 with a real, source-provided %-of-conservation-pool-full figure.
Why it exists
The data riders and boaters, farmers, and lake-house owners need — is this lake up or down, and by how much — is public, but it lives siloed across individual USGS gauge pages and per-district Army Corps of Engineers reports, with no national view. This project turns that same public data into a single searchable reference.
How it's built
Every figure comes directly from USGS Water Services (current instantaneous values and a 90-day trend) and USACE CWMS Data (storage, a genuine %-of-conservation-pool-full figure where the district publishes one, and a small number of lakes with no nearby USGS gauge at all). The method behind each number — including a documented pass that removes a handful of contaminated sensor readings before display — is on the methodology page, and every page carries a data-vintage stamp. Nothing on the site is sponsored, and no page is pay-to-rank.
An independent project
Lake Level Tracker is an independent data project, not affiliated with the U.S. Geological Survey, the U.S. Army Corps of Engineers, or any government agency. It is informational only: readings are provisional and not for navigation or safety decisions. Always confirm current conditions with the managing agency. Corrections are welcome — see the contact page.
