Information on Carol Lake

Ordinary High Water      883.10 

100-Year Flood Elev.     886. (District, 10-day snowmelt) 

 Carol Lake is a shallow lake with surprisingly good water quality. Carol along with upstream North Twin, South Twin, Silver and Loon lakes form the headwaters of the Silver Creek Flowage. Future development of this lake, if not managed properly, could result in increased phosphorus loading resulting in degradation of water quality. Carol Lake is downstream of Loon Lake and South Twin Lake which are impaired waters. Based on measured lake characteristics and land use in the lake’s minor subwatershed, water quality modeling indicates that minimal protection efforts to reduce phosphorus input to the lake can help maintain its good water quality. Some residents did raise a concern that the outlet culvert was keeping the lake levels higher than they historically were.
