About Lake Levels Today

Lake Levels Today shows the current water level of more than 400 US lakes and reservoirs on one page each: the gauge elevation, feet above or below full pool, percent of conservation pool, the 24-hour, 7-day and 30-day change, and a one-year chart with the pool lines drawn on it.

The data is the operating agencies' own. Corps of Engineers reservoirs come from the USACE Access to Water service and Texas reservoirs from the Texas Water Development Board. A script pulls both feeds once a day, keeps a rolling 400 days of daily means for every lake, and rebuilds the whole site as static pages. Nothing is estimated or interpolated, and every lake page links to the source it was read from. If a feed fails the previous day's value stays up with its original timestamp rather than a guess.

It exists because the agency pages are accurate but scattered: one site per district, tabular pages built for engineers, no context about what full pool means on that lake. This site puts breadth and context on a page that works on a phone at the boat ramp. It is free, carries no ads today, and asks nothing of you: there are no accounts, no tracking beyond basic page analytics, and no cookies you have not agreed to.

It is built and maintained by a single developer. Missing lakes get added in the order people ask for them.
