From the record
What the reports say
Written by National Weather Service staff at the time of the event · public domain
The Sevier River at Sigurd peaked at 1728 cfs on June 1st, then remained above flood stage for more than a week after that as it slowly receded. Many roads across Sevier county continued to be impacted and damaged, including State Road 118 between Joseph and Monroe, the Sevier River Road between Central Valley and Annabella, and Seegmiller Lane near Richfield. In addition, flood waters seeped into about a dozen homes, while threatening more than a dozen others.
Flooding occurred along the Sevier River, with the gauge at Sigurd topping flood stage on May 23rd, and slowly rising through the rest of the month with the accelerated snowmelt. This flooding effected low lying roads and bridges, including Sevier River Road and Nebeker Lane. Both of these roads were closed for several weeks, and Nebeker Lane suffered severe damage due to the flood waters. Note that this event continued into June.
A strong thunderstorm ripped through the Sevier Valley, knocking down a 200-foot section of building in Richfield, and blowing down large trees in Monroe. The strongest recorded wind gust was 48 mph (42 kts), but stronger gusts likely occurred with this storm.
