Rainy and Namakan lakes are expected to rise another foot before May 22. Other lakes are also high. Lake of the Woods is up 3 to 4 feet this spring. Upper and Lower Red Lakes are up 2 feet and Mille Lacs lake farther south is up almost a foot and a half. In the Twin Cities, Lake Minnetonka is up a comparatively modest, foot.

Even Lake Superior is up a foot this spring. That’s huge considering its size.
