Episode Narrative Heavy rainfall, with up to two inch per hour rates, resulted in numerous reports of flooding across western Colorado including the Gunnison River which rapidly rose in the Gunnison River Gorge. The excess rainfall also caused several mud slides which temporarily closed area highways.
Event Narrative Heavy rainfall resulted in the Gunnison River stage rapidly rising about 4 feet through the BLM's Gunnison Gorge Wilderness Area. Numerous camp sites and trail heads were destroyed or covered in debris and boulders to the point that they were no longer usable. The movement of boulders and silt significantly changed the characteristic of the Gunnison River in a number of places, such as the Miracle Mile rapids where rapids no longer exist. Six river runners were trapped at the T-Dyke boater site during the event. Numerous small fish were killed by the flash flood.
