Isle Royale National Park

In August, Isle Royale NP took lethal measures to control a problem wolf due to the escalating number of concerning incidents reported by park visitors. After extensive monitoring and attempts at deterrence, and in consultation with state, federal and tribal agencies, the difficult decision to lethally remove this wolf was made. Park personnel will continue to track wolf/human interactions and remove additional wolves only if necessary.

On August 21, 2025, join Isle Royale National Park and Kaleidoscope for Ranger III Family Day. Families with children 15 or younger may reserve space aboard one of two, 45-minute scheduled waterway cruises. Ranger III will travel into Portage Lake and back during the trip.

This summer, Isle Royale National Park is partnering with the Michigan Department of Natural Resources (DNR) to conduct a creel survey of the Isle Royale-Lake Superior fishery.
