| Episode Narrative |
Excessive snowmelt runoff filled Big Horn Lake from late June through mid-July. Gusty winds combined with the already high water in the lake to cause significant problems on area roads in late July. |
| Event Narrative |
Excessive snowmelt runoff caused flooding at Big Horn Lake. The lake elevation hovered about 15 feet above full pool at 3,655 feet. High water neared the level of the US Highway 14A causeway across the southern end of the lake. Wind gusts to 45 mph caused waves that eroded some of the embankment along the causeway and deposited debris onto the highway. On Friday night, July 22, the waves deposited enough debris to necessitate snowplows to come and clear the highway. County Road 20 along the west shore of the lake was inundated and sustained significant damage as a result of the prolonged period of high water. |
