On August 2, an intense rain shower event occurred in the Monture area just north of Ovando, MT. The combination of intense rain, very steep slopes, geology, and 2017 post-burn conditions resulted in debris flows within the tributaries of Spread, Falls, Bill, and Yellowjacket Creeks. The debris flows impacted the Monture Campground, Monture Outfitter and Guide camp, and Monture Creek Trail (#27) at Spread and Bill Creeks. No people were injured in the debris flow.
Due to this weather event, Monture Creek is extremely muddy/lacking clarity and producing discoloration down into the Blackfoot River. This muddy water is expected to last several days and will begin to clear when the debris flow and channels stabilize. As rain showers develop over the summer months, these discoloration events are expected to reoccur and movement of debris and water within the Rice Ridge burned area is common. The public is reminded to exercise caution when recreating in this area.
Forest Service personnel will be flying over the drainage to survey and assess the extent of the debris flow and its impacts. A closure order will be forthcoming. Until the area is assessed and the trail is cleared, the trail will remain closed for public safety.
