The closure will be in place for seven days and may be modified or extended as conditions allow. This is the first announcement this summer to denote Boundary Waters Canoe Area Closed.
The Boundary Waters Canoe Area Wilderness stopped issuing entry permits Saturday, closing all land, water, trails, portages, campsites, canoe routes, and wilderness entry points until Aug. 27.
