ELY — U.S. forestry officials said the last remaining wildfire in the Boundary Waters Canoe Area Wilderness has been declared 100 percent contained.

The 188-acre Knife Lake fire will be declared officially controlled once additional clean-up work is finished. Two firefighters remained on the scene Saturday for patrol work and clean-up.

The fire was located near the South Arm of Knife Lake, northeast of Ely near the U.S.-Canadian border. The largest fire burned at least 15 to 20 acres.

A Superior National Forest spokeswoman said heavy rains last week helped aid the containment efforts.

All waterways, portages and campsites near the South Arm of Knife Lake have been reopened for water activities. Standard campfire restrictions are also in place.
