Weather

Water Conditions

  • Algal Blooms - Intermediate Lake, Chickenbone Lake, Lake Richie, & Lake Livermore 

    • Until further notice: Do not drink, filter, or boil water from Intermediate Lake, Chickenbone Lake, Lake Richie, and Lake Livermore. Filter or boil water prior to traveling to these lakes. These lakes are experiencing a cyanobacteria harmful algal bloom. Some species of cyanobacteria are toxic to humans. If ingested, it can cause headaches, nausea, vomiting, diarrhea, and damage to internal organs. Skin contact can cause irritations. Filtering or boiling water will not remove toxins and may add them. 

  • Caution - Algal Blooms:

    • Visitors should use caution not just on any inland lake that appears to have algal-bloom like symptoms (pea-soup, green sludge, blue-green blobs). Visitors are encouraged to report any sightings to park rangers and avoid interacting with water with suspect conditions.

  • Island Mine Campground: The water at the creek near Island Mine Campground is running but the water level is low. A water filter with a pumping mechanism works best. 

Facilities

  • Rock Harbor Dock Construction: The Ranger III dock in Rock Harbor is closed. Visitors should expect frequent, loud construction sounds (saws, drills, heavy equipment) through the end of October.

  • Fuel at Rock Harbor and Windigo through 9/11: Rock Harbor and Windigo have both gasoline and diesel available through September 11, 2021. From September 12 through October 31, 2021, fuel will not be available on-island. Boaters should bring extra fuel in legally approved containers.

  • Visitor Centers Hours

  • Rock Harbor Lodge: Closed for the 2021 season.

  • Windigo Store: Closed for the 2021 season.

  • America Dock: The America dock in Rock Harbor is closed for the foreseeable future due to unstable conditions.

Wildlife Sightings

  • Moose

    • Moose sightings are common in Rock Harbor, Windigo, and along numerous trails. Admire from a distance. Moose are in their mating season, also known as the rut, which lasts through early to mid October. Bull moose can exhibit extremely unpredictable behavior during this time. If needed, use a tree to create a barrier between yourself and rutting bulls.

  • Wolves

    • There have been many wolf sightings on the park’s east end. Wolves are wild, unpredictable creatures. If you see a wolf, do not approach. Encourage it to move along by clapping your hands and raising your voice. Keep your distance and do not turn and run. Wolf attacks on humans are exceedingly rare but if a wolf were to attack, fight by any means necessary. 

Flora, Fungi, and Other Sightings

  • The fungus is among us! Be cautious with consuming fungi as there are many toxic species throughout the park and identification can be difficult.
