Lake data
How high it is, how fast it’s moving, and which ramps that leaves open — for every lake we cover, free, from any browser.
No account. No download.
Elevation readings are public. Making them mean something — is it up or down, is that a lot, can I still launch — is the part nobody does.
The current reading, plus how far the lake has moved overnight, this week, this month and this year. One glance tells you whether it's filling or dropping.
How much water is actually in there against how much it holds — the number that tells you what kind of season you're looking at.
Overlay this year against previous ones and see where you sit. Compare against the ten-year average, or the year's own high and low.
Which ramps that level leaves usable, with the reported status where there is one — so the number turns into a decision about where to launch.
What's coming in from the rivers and what the dam is letting out, day by day — the two numbers that explain everything else.
Everything above is free. LakeStats Pro adds an ordinary weather forecast, pulled for the lake itself rather than for the town you’d otherwise look up — and sitting on the same screen as the water level.
Forecast data from Open-Meteo, refreshed through the day. It’s a general weather model at the lake’s location — not a marine forecast, and it doesn’t predict chop.
Where it comes from
We don’t measure anything ourselves. The readings come from the Bureau of Reclamation, the USGS and the Park Service, and we check for new ones every half hour — then label each reading with the day it describes rather than the day it turned up.
The water numbers are free and always will be. The app adds the depth map.
