Southwest of Muskrat Lake, Old Mud Lake can only be viewed from its northeastern corner along 54th County Road. Mono filament line and corks wrapped around a utility line above the ditch that flows through a large culvert into the lake attest to this site being a popular local fishing hole. There is a small area for parking on the county right of way immediately south of this culvert.

This is the deeper part of this approximate 130 acre lake. It attracts diving ducks and other birds preferring open, deeper water. It can produce Tundra Swans and Cackling Geese during migration. The field immediately north of Old Mud Lake can produce a good variety of sparrows. If it has been burned, Swainson’s hawks will use it when they move through the area.
