Episode Narrative The warmest temperatures of the summer season produced snowmelt runoff in the drainages of the western Bighorn Mountains. Creeks and streams in Big Horn and Washakie counties quickly rose in response to the increased runoff. The flooding subsided during the morning of July 1. More information about the conclusion of this flood episode is found in the July 2011 Storm Data publication.
Event Narrative Temperatures approaching 70 degrees around 9,500 feet melted snow and caused the water level on Tensleep Creek to quickly rise during the overnight hours of June 29 and 30. The flood waters washed out a road leading to the Wigwam Fish Rearing Station and to a private residence near the mouth of Tensleep Canyon east of town. Several residents also reported flooding of their yards and at least one reported an out-building being inundated by water.
