## About

Flour Lake is a 330-acre lake near Grand Marais in Cook County, Minnesota. It reaches 75 feet at its deepest point, and has roughly 8.5 miles of shoreline. DNR surveys put average water clarity at about 15.4 feet, which is exceptionally clear for Minnesota. Access is by portage through Superior National Forest; most lakes reached this way lie in or beside the Boundary Waters Canoe Area Wilderness, where an entry permit is required.

Minnesota DNR fisheries surveys list 8 fish species here, including walleye, northern pike, smallmouth bass, yellow perch, lake trout, and tullibee (cisco). The DNR has stocking records for the lake, so check the stocking report for the most recent species and year classes. Special fishing regulations apply to smallmouth bass, and they override the statewide limits. The most recent fisheries survey on file dates to 2025.

There is one public boat launch (concrete surface) managed by the US Forest Service. OpenStreetMap shows a swim beach on or beside the lake. Flour Lake Campground and Golden Eagle Resort are mapped close to the shoreline for overnight stays. The lake is listed as infested with spiny waterflea — clean, drain and dry your boat and gear before leaving.
