What happened
Flooding continued to worsen in Huron County on June 22nd even after the heavy rains had ended. The City of Norwalk was especially hard hit as flooding from Norwalk Creek affected much of the city. Flood waters on Water and Elm Streets rose to as much as 12 feet in depth on the 22nd. Evacuations continued throughout the day as water levels climbed. Additional rainfall during the aftenoon further aggravated conditions. Water levels finally receded on the 23rd revealing the devastation the flooding caused throughout the county. Over a dozen homes in the county were classified as being destroyed with another 35 to 40 with major damage. Close to 200 homes were classified as having minor damage with another 600 to 700 sustaining damage from basement or nuisance flooding.

What happened
Thunderstorms dumped torrential rains on Huron County during the late evening hours of June 21st and early morning hours of the 22nd. Widespread and devastating flash flooding occurred as a result of this rain. Damage in the county was the worst since the storms of July 4th, 1969. Between 5 and 9 inches of rain fell on much of the county. Cooperative observers in Norwalk measured a storm total of 5.70 inches with a spotter report just south of town of 6.66 inches. Other reports included 6.0 inches in New London and 4.20 inches in Fitchville. Most of this rain fell in a three to four hour period. Runoff from this rain caused area streams and rivers to quickly rise. By 3 a.m. evacuations were under way in Norwalk where flood waters around two feet deep were already being reported on the ground floors of several homes. Evacuations were also conducted near Clarksfield around the same time. Many of these evacuations were conducted by boat. Water levels continued to rise as daybreak approached. Dozens of roads in the county were washed out or flooded with water in some areas several feet deep. Dozens of vehicles became stranded in the flood waters and many motorists...
