WhenEvent Place namedHarm What the report says
August 2009HailGreybull1 hurt, $75,000Hailstones of golf ball size were numerous at a residence in Greybull. Some stones reached two inches in diameter.
June 2011FloodGreybull$300,000Shell Creek and its tributaries caused flooding in and around the community of Shell. The flooding was a result of continued snowmelt in the western Bighorn Mountains as the warmest temperatures of the season were attained. Damage was reported on the Kedesh Guest Ranch and a county road along Trappers Creek.
March 2014FloodGreybull$250,000Flooding of the Spence Oil Field and other areas north of Greybull occurred along the Big Horn River. Three homes outside the Greybull levee system had minor flooding.
June 2011FloodGreybull$150,000Flooding occurred on Shell, Horse, and Trapper creeks as snowmelt runoff increased. Lowland near the creeks and at least one guest ranch were impacted by the rising waters. No bridges were damaged by the high waters but several area roads were inundated and damaged.
June 2008Flash FloodGreybull$25,000A thunderstorm moving east along Dry Creek toward Greybull produced one to two inches of rain in Greybull in less than one hour. The town emergency manager reported a few rain gages in town measured slightly more than two inches of rain in 50 minutes. Pea sized hail of one inch in depth also occurred with the heavy rain. The Greybull storm drainage system was unable to keep up with the deluge of water and hail, flooding many prone areas around town. The heavy rain flooded portions of the Greybull River Road and several basements in town sustained damage.
June 2015FloodGreybull$5,000Minor flooding of the Greybull River occurred just south of Greybull near State Highway 789. The flooding occurred at the confluence of the Greybull River and the rain-swollen Big Horn River. Heavy rain of the previous week had filled the Big Horn River and the snowmelt run-off in the Greybull River began to back-up near the confluence. A small levee was reported to have collapsed upstream of the confluence causing further problems. Sandbags were deployed to prevent damage. Most of the flooding was confined to low-lying areas and little damage was reported.
