The Bureau of Reclamation and the Caribou-Targhee National Forest are monitoring landslide activity and have roadway caution signs in place warning motorists of the potential for danger. Flashing yellow caution lights will be visible to drivers heading over the top of Palisades Dam.
The landslide area is located about a quarter-mile upstream of the left abutment of Palisades Dam. Geologists for both agencies have been monitoring the slide zone and have confirmed movements in some locations. In the event that the roadway is not accessible to traffic, there is an alternative route across the Snake River about 15 miles downstream of Palisades Dam. However, this road may not be wide enough for vehicles pulling trailers or recreational vehicles to pass one another.
The active landslide area covers about 13 acres and stretches across about 1,000 lineal feet above Bear Creek Road which leads to the Calamity Boat Launch area and private property. Reclamation and the Forest Service will continue to monitor the situation and advise the public. The Bonneville County Sheriff's Office has also been informed of the potential for danger and the public warnings.
Reclamation has determined that no adverse impacts would occur to Palisades Dam should the landslide area fail.
