Brule Lake is a lake in Cook County, Minnesota. It is situated between two long sills in the Superior Upland, causing the lake to be eight times longer east and west than it is north and south. Out of the opposite ends flow the Temperance River and the South Brule, a tributary of the Brule River. Brule Lake was logged heavily in the early 1900s, and the region around it was consumed in 1929 by a logging-related forest fire which bears Brule Lake's name. Now the lake is part of the protected Boundary Waters Canoe Area, a federal wilderness area for which Brule Lake serves as an entrance point.
Brule Lake is one of the largest lakes in the eastern Arrowhead Region of Minnesota. It has an area of 4272 acres, and a maximum depth of 78 feet. It sits 1851 feet above sea level. It measures approximately eight miles from east to west, and one mile from north to south. Brule Lake is located in the Duluth Complex, a geological region marked by bands of softer, more erodible bedrock, and "red rock," a harder and less easily eroded stone, which forms protruding ridges across the Superior Uplands. In the region of the Brule, these ridges run nearly exactly east-west, and long, thin lakes lie between them. The valley in which Brule Lake is located is bound on the north by the Misquah Hills, and on the south by another sill peaked by Brule Mountain. Though the distance between these points is only four miles, the valley is six hundred feet deep. Brule Mountain, Misquah Hill (Point 2230), and Eagle Mountain are all prominent red rock monadnocks surrounding Brule Lake. Misquah Hill was erroneously identified as the highest point in Minnesota during the 1890s, until the United States Department of the Interior resurveyed in 1961, concluding that Eagle Mountain was taller by 74 feet.
Brule Lake is the source of both the Temperance and the South Brule Rivers. The Temperance drains from the west side of the lake, and flows some thirty miles until entering Lake Superior near Tofte. The South Brule drains from the east and flows some forty miles until entering Lake Superior forty three miles northeast of the mouth of the Temperance. The Temperance and Brule have the fourth and third largest catchment areas of any stream entering Lake Superior in Minnesota. Separated from the mainland by these two watersheds are the Poplar, Cascade, and Devil Track rivers, which drain a total of slightly over 300 square miles of land themselves.
