SatelliteLoading NASA SWOT passes
000.00ft above sea level
Measured from orbit by NASA's SWOT satellite each time it passes over the lake, usually every 10 to 21 days, to within about half a foot. Elevation is above sea level (EGM2008), not a gauge reading at a dock.
Background reading: Lake Walcott on Wikipedia
Lake Walcott is a 11,783-acre reservoir in Idaho.
We have not matched Lake Walcott to a public level gauge, so the water level on this page comes from NASA's SWOT satellite, which measures the lake surface from orbit on each pass. Wind, gusts and rain come from the National Weather Service forecast grid that covers the water.
With this much open water, waves build quickly when the wind lines up with the long axis of the lake. Pick a launch on the upwind shore on breezy days and the ride home is easier.
The go or no-go calls above are a starting point, not a guarantee. Read how we score conditions, and always check local rules and posted warnings before you launch.
The National Weather Service forecast for the lake from October 26: Monday: S wind 10 to 13 kt, gusts to 22 kt, high near 60°F, 61% chance of rain. The panel at the top of this page refreshes the current wind, gusts and direction when you open it and turns them into a call for sailing, paddling, power boating and fishing.
We have not matched Lake Walcott to a public level gauge, so the water level card on this page uses NASA's SWOT satellite, which measures the lake surface every time it passes overhead, usually every 10 to 21 days. The card shows the latest pass, its date and the change since the pass before.
Lake Walcott covers about 11,783 acres (18 square miles) of surface water.
