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.
Set in Lake and Peninsula Borough, Alaska, Nonvianuk Lake is a 32,618-acre natural lake. The water surface sits about 643 ft above sea level.
We have not matched Nonvianuk 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.
On a lake this size the wind has miles of open water to work with, so a 15 kt breeze can stack up a steep chop in the main basin while sheltered coves stay flat.
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 25: Monday: SW wind 8 to 15 kt, gusts to 22 kt, high near 47°F, 75% 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 Nonvianuk 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.
Nonvianuk Lake covers about 32,618 acres (51 square miles) of surface water.
