A wave created by a landslide on Spokane Tribal lands across the Spokane River from a Lake Roosevelt National Recreation Area campground destroyed a dock at a public boat launch.
The slide occurred about 1:30 p.m. across the river from the Porcupine Bay Campground and launch, said Deputy Brad Sweet with the Lincoln County Sheriff’s Office. The slide created a 5- to 6-foot wave, witnesses said.
The wave traveled across the river, and destroyed some personal watercraft and the launch as it slammed into the shoreline, Sweet said. No injuries were reported.
The campground is maintained by the National Park Service.
