What the National Weather Service wrote
At approximately 0830 MST on Thursday, May 11, 2023, high flows on the Lower Ogden River eroded the embankment supporting state Route 39 through Ogden Canyon which caused one lane of the two lane road to collapse. An upstream river gauge reported flows above action stage (greater than 1264 cfs) from April 14 through May 2, and again from May 4 through the time of the incident. Flows approached minor flood stage (1610 cfs) within 100 cfs throughout this time, but exceeded minor flood stage by 5 cfs at one observation time on May 9, 2023. The road was closed for approximately 11 hours, with the one stable lane allowed to reopen thereafter.
