Before you read the numbers
Where do these lake levels come from?
From the agencies that run the dams and gauges: the U.S. Army Corps of Engineers (most lakes here), the U.S. Bureau of Reclamation (Lake Mead, Lake Powell and other western reservoirs) and the U.S. Geological Survey (natural lakes such as Great Salt Lake). Each lake page links to its source.
What does “full pool” mean?
Full pool is the level a reservoir is meant to hold for water supply, power and recreation. Water above it is flood storage that the dam releases over time. Many Corps lakes lower their full pool in winter, so we compare against the value that applies today.
How do you decide what is “normal”?
For each lake we take its level on the same calendar date in every past year we hold (up to 30), and call the middle of that spread the normal. “Lower than usual” means below the level of three out of four past years on that date.
Why is my lake missing?
We only publish lakes whose agency gauge is online and has at least five years of daily history. Lakes run by private power companies are not in the federal feeds. Write to us and we will check whether a public gauge exists.
