Four preserves totaling 57 acres, with over 1/2-mile of frontage on Crooked Lake and Crooked River. Scenic area just south of Alanson. Ten acres along the lake are northern fen with sedges, grasses and shrubs; the remainder of the preserves consist of rich conifer swamp dominated by northern white cedar. The Inland Waterway Preserve has a 1/4-mile trail from Lake St. to a scenic spot on the Crooked River. A gravel-surfaced limited-depth boat launch site is located at the end of Lake St. near Crooked River Lock just north of the preserves; it provides an access point for paddlers to enjoy the scenic lake frontage. Waterfowl hunting, by written permission only, is allowed only at the Inland Waterway and Ponshewaing preserves. Access to the complex is from a gate on Lake St.; there is no formal parking lot but parking is allowed along the road near the gate.
