Middle Pomme de Terre Sub Watershed

The Pomme de Terre from Barret Lake north is located within the North Central Hardwood Forest, differing from the rest of the watershed which is located in the Northern Glaciated Plans. The landscape change becomes noticeable from the rolling hills above the Pomme de Terre chain of lakes as it flows south into a widening and flattening flood plain with fewer trees surrounding the river’s edge. Between Barret Lake and the Pomme de Terre chain of lakes, biological impairments are linked to several stresses as identified in the MPCA Stressor ID report, including low dissolved oxygen levels, habitat, altered hydrology, and obstruction of fish passage.

Perkins Lake:

Perkins Lake is a shallow, moderately eutropic natural impoundment of the Pomme de Terre River, although a dam does exist to control water levels to aid in prevention if winter fish kills and sustaining recreational fishing. Along with its sport-fishing opportunities, the lake hosts many species of waterfowl during fall. The lake’s surroundings is dominated by agricultural land, though it is fairly well buffered by natural areas, US Fish and Wildlife easements, and wetlands. Excessive nutrient inputs are likely from upstream sources.
