About Lake Level Watch

Today's water level for 153 lakes and reservoirs in the United States, straight from official government gauges, updated every day.

Why this site exists

Most lake level pages show a single number. But “908 feet” means little on its own: is that low? Normal for September? Lower than last year? Lake Level Watch answers that question by comparing every reading with what is normal for the same date, based on up to 20 years of official daily data, so you can tell a routine seasonal drawdown from a real drought.

Who runs it

Lake Level Watch is built and maintained by Ellyana and published by Cosmabella LTD.

How the numbers are made

• Every reading comes from a public agency: USGS, the U.S. Army Corps of Engineers, the Bureau of Reclamation, the Texas Water Development Board, TVA, California DWR and NOAA.
• “Normal for the date” is the median level on that calendar date over 2006–2025; the normal range is where the lake stood in 8 of 10 years.
• If a number is missing at the source, we show it as missing. We never estimate or fill in a reading.

The full details are on the data sources & methodology page.
