Bug Report


  • Stay Night Limits: Rock Harbor, Three Mile, Lane Cove, and Washington Creek Campgrounds have a 1 night stay limit through 9/17. All other campgrounds are unlimited stays.


  • Trail Navigation: Expect slow hiking conditions due to downed trees. Beaver activity changes hydrology causing water-logged trails or blockages that must be navigated around. Bring hiking poles to assist with difficult sections and wear sturdy, well-broken-in footwear. Have a map and compass and know how to use them.


  • Fall Weather: Warm temperatures during the day and cool temperatures at night. Bring layers and rain gear for a variety of conditions.
  • Water is Life: Stay Hydrated

Water Conditions

  • 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.
    • Lake Richie & Chickenbone Lake Water Warning: Do not drink, filter, or boil water from Lake Richie or Chickenbone Lake. Filter or boil water prior to traveling to the area. These lakes are experiencing a cyanobacteria algal bloom. It is harmful to ingest.


  • Cow Moose with Calves: Cow moose are extremely protective of their calves. If you see a cow moose (no antlers), look to see if there is a calf around. If a cow moose were to approach, protect yourself by putting a large tree or rock between you and the moose.
  • Moose Rut: Moose are in the rut, also known as moose mating season. Bull moose behavior during this time of year can be extremely unpredictable. Sometimes rutting bull moose exhibit aggressive behavior towards people. Give bulls extra space and protect yourself by putting a large object between you and the moose.
  • Wolves: If you see a wolf, do not approach. If the wolf comes closer, encourage it to leave by clapping and yelling. If you cannot safely leave, make yourself big and aggressively use hiking poles or branches. Wolf attacks are extremely rare and unlikely to happen, but if it does, fight by any means necessary.
  • Stinging Insects: Dry summers often result in an abundance of wasps. Bring an epinephrine kit if allergic to stings.


Check if dive buoys are currently on or off station.
