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: Castle Rock Lake on Wikipedia
Castle Rock Lake covers about 12,981 acres in Adams County, Juneau County, Wisconsin and is classed as a reservoir. The surface sits about 883 ft above sea level and the deepest point is roughly 35 ft down.
We have not matched Castle Rock Lake 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: ENE wind 6 to 8 kt, gusts to 16 kt, high near 56°F. 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 Castle Rock Lake 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.
Castle Rock Lake covers about 12,981 acres (20 square miles) of surface water.
The deepest point of Castle Rock Lake is roughly 35 ft.
