Big Sandy Lake is a lake in Aitkin County, Minnesota, approximately nine miles north of McGregor. The lake is considered fertile walleye ground with several habitat types, including the open main basin, the deep, cold eastern basin, and a shallow, more isolated south basin. Shallow bays containing dense beds of wild rice are found on south, west, and northwest sides of the lake.
Public access is provided by the Minnesota Department of Natural Resources at two locations, the first on the Sandy River north of the "Pier 65" bridge, and the second on the northeast side of the lake. Additional points of access are maintained by the Corps of Engineers and by various municipalities.
Big Sandy Lake is a reservoir and was created in 1859 when the United States Army Corps of Engineers built a dam on the Sandy River. When the dam was built it included a lock to allow boats to travel out to the Mississippi River. The lock has since been shut down and the lock house has been turned into a small museum containing local artifacts. Big Sandy Lake has three major tributaries Sandy River, Prairie River, and Aitkin Lake Creek. Sandy River enters the lake from the south and empties back into itself after the Big Sandy Dam, on the northwest corner. Priaire River enters the lake from the east into Bill Horn Bay. Aitkin Creek enters the lake from the northwest, near the Big Sandy dam.
Big Sandy Lake was inhabited by the Dakota Sioux until they were removed by the Ojibwa. In the Ojibwa language, the lake is known as Mitaawangaagamaa, meaning "Lake with flat, sandy beaches." The lake is home to the Sandy Lake Band of Mississippi Chippewa who are now part of the Mille Lacs Band of Ojibwe, but have been working on regaining their independent recognition restored by the Bureau of Indian Affairs. The Minnesota DNR also owns one island in Bill Horn Bay that they preserve. In the 1800s this was the island where the Sioux women and children hid from the attacking Ojibwa.
In 1798, North West Company maintained a post on the western side of the lake; in 1830, American Fur Company established a post at the confluence of the Sandy River with the Mississippi River, a short distance west of the lake. Originally located on the north shore of Big Sandy Lake, the village of Gaa-mitaawangaagamaag was the western terminus of the Northwest Trail that connected the Mississippi River with the Saint Louis River; Savanna Portage State Park that commemorates this historic trail is located on the northeastern shore.
In 1850, the United States attempted to remove the Ojibwa population out of Michigan and Wisconsin to areas west of the Mississippi River, resulting in the Sandy Lake tragedy. A memorial commemorating the Sandy Lake tragedy was established at the United States Army Corps of Engineers Sandy Lake Dam Campgrounds. Along Minnesota State Highway 65, a rest area with a view of Sandy Lake was established, enhanced with a Historical Marker plaque to further commemorate the Sandy Lake tragedy.
