About South Arm Knife Lake

South Arm Knife Lake covers about 1,938 acres in Lake County, Minnesota and is classed as a natural lake.

We have not matched South Arm Knife Lake to a public USGS level gauge, so this page leans on wind and weather from the National Weather Service forecast grid over the lake. If you know of a gauge or a lake association that publishes levels, tell us and we will add it.

Mid-sized lakes like this one tend to have shifty, gusty wind near shore and steadier pressure in the middle, which is why gust spread matters as much as average speed.

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.
