Record breaking snowfall for the 2022-2023 winter season was received across all of northwest Wisconsin which was about 200% of normal snowfall. Much of this snowpack remained on the ground into April. Warm temperatures 10 to 20 degrees above normal during the second week of the month led to rapid snowmelt across the region with fast rises on area waterways. This above normal warmth was quickly followed by a late season storm that brought heavy rain and heavy snow to the region and further exacerbated the ongoing flooding. Roads began being impacted on the 12th with water over roads and quickly escalated to washouts, failed culverts and gravel roads stripped over the next few days. Most of the runoff had routed through the area by the 20th with conditions improving over the remainder of the month, although localized impacts to basements, farm fields, etc. continued into early May. Due to the extent of the damage to roads, numerous entities declared states of emergency to assist with the recovery efforts.
