What the National Weather Service wrote
Snow melt flowing downstream from the Absarokas brought flooding and high water along the South Fork of the Shoshone River. At the Ishawooa Bridge, downstream from Valley and near Aldrich Creek, the high water severely damaged the bridge. The bridge remained open, but was reduced to one lane while repairs were made. Waters receded on the 11th as cooler mountain temperatures slowed snow melt.
The wider storm
After an exceptionally snowy winter and cool spring, warming temperatures brought rapid snow melt to the Absarokas. In addition, locally heavy rain fell helping speed the melting of snow. As a result, the South Fork of the Shoshone River rose rapidly and flooded. Along South Fork Road, downstream of Valley and near Aldrich Creek, the water damaged the Ishawooa Bridge. The bridge remained open, but was restricted to one lane while repairs were performed. Conditions improved when waters dropped on the 11th of June as cooler mountain temperatures slowed snow melt.
Began near Valley (44.2550, -109.5152).
