The modern campgrounds at both parks were closed Wednesday for the remainder of the season.

Park staffers at Porcupine Mountains Wilderness State Park closed the Union Bay Modern Campground after almost three weeks of rain.

“The park has received nearly 18 days of continuous rain and the campsites are completely saturated,” said Michael Knack, park supervisor. “All of the campsites have standing water and ruts from vehicles and campers that have been getting stuck.”

The Presque Isle Rustic Campground, cabins, yurts and backcountry campsites will all remain open. The closure at Union Bay comes about one week before park personnel would have turned off the water and winterized buildings.

Lake Superior waves roll in toward a flooded and rutted campsite at the Union Bay modern campground at Porcupine Mountains Wilderness State Park in Ontonagon County.

Hikers and backcountry campers are being urged to not take any unnecessary risks and to evaluate thoroughly any attempts at informal river crossings.

“The river and creek currents are turbulent, and waters are much deeper than normal,” Knack said. “Use extreme caution.”

The most current closures and trail conditions at the Porcupine Mountains will be available at the Wilderness Visitors Center.

The campground at Baraga State Park was closed Wednesday, roughly two weeks early, due to flooding in about 90 percent of the campground, said Kelly Somero, DNR western Upper Peninsula recreation programmer. Camis USA, Inc., the DNR’s reservations contractor for state parks and harbors, will contact those with reservations to provide refunds, she said.

“Our current campers will be able to stay until they were due out or they can be refunded if they wish to leave early,” Somero said.

The Otter Lake Boating Access Site has extreme flooding. The skid pier is completely submerged and the launch is not usable.

“We have reports that Big Eric’s Bridge State Forest Campground, King Lake State Forest Campground, Bond Falls Scenic Site, Prickett Dam Boating Access Site and other DNR sites in Baraga, Houghton and Ontonagon counties have very high water levels, so visitors should exercise caution when visiting these sites,” Somero said.

Other state park campgrounds in the western Upper Peninsula also are experiencing wet campsites. Those planning to visit should call to check on camping conditions.

Twin Lakes State Park staffers in Houghton County reported their campground is relatively dry and the park has availability for the upcoming weekend.
