Overview The Sandy Lake Dam and Recreation Area is situated at the outlet of Big Sandy Lake in northern Minnesota, 13 miles north of McGregor, MN. The dam is a part of the Mississippi Headwaters Project, one of the first reservoir systems in the country, and the Sandy Lake Dam structure dates back to 1895. Today the grounds have been developed into a park and campground that is noted for its clean, family-friendly environment and access to fishing and boating on both the lake and nearby Mississippi River. It offers the only public campground and beach on Big Sandy Lake. The area is also a part of the historic canoe route that connected the Mississippi River to Lake Superior and major fur trading companies. Artifacts from the area's long history are kept in a small museum located near the dam. Recreation Sandy Lake offers many recreational opportunities including camping, boating, swimming, picnicking, birding and hiking. Anglers enjoy fishing the lake and river for Northern pike, walleye, small mouth bass, bluegill, crappie and even catfish. Playgrounds are located on both sides of the dam and are located near the beach and visitor museum areas.
