About Lakefullness

Searching for a lake's level usually turns up a dam operator's raw table, a news story from a drought years ago, or a page that copied a number once and never updated it. Lakefullness reads the gauges on the dams directly, several times a day, and puts each reading in context: full pool, the normal for this calendar date, the same day last year, and the trend over the past month.

What we publish

• A page for each of 340 lakes and reservoirs run by the U.S. Army Corps of Engineers and the U.S. Bureau of Reclamation, plus natural lakes the U.S. Geological Survey measures.
• State pages and a national ranking from lowest to fullest.
• A dock check on every lake page: type the elevation of your dock or ramp and see how often the water has dropped below it in each month.

What we do not do

We do not forecast, and we do not edit the agencies' readings. When a gauge goes quiet or a lake has too little history to say what is normal, the page says so and stays out of search results until the data returns.

Independence
