Flood 
of 1955
Permanent Online Exhibit

The Naugatuck River overflowed its banks on August 19, 1955, devastating towns along its path. This catastrophic event resulted from back-to-back hurricanes, Connie and Diane, which dumped record-setting rainfall across Connecticut. Hurricane Connie arrived first, saturating the soil with 4-6 inches of rain. Less than a week later, Hurricane Diane added more than a foot of rain, leading to rivers across the state, including the Naugatuck River, spilling over and causing severe flooding.

Connecticut experienced 87 deaths due to the floods, with eight fatalities occurring in Naugatuck. Survivors often referred to the flood as “Black Friday” due to the destruction it caused, particularly on August 19, when rivers across several towns burst their banks in the early hours of the morning. Damage was extensive, and recovery efforts stretched for months, with the flood forever altering the physical and economic landscape of Naugatuck.

Later in the same year, a second, more minor flood hit Connecticut on October 15-16, 1955, further straining the recovery efforts in many areas, including Naugatuck.

The photographs in this collection, generously donated to the Naugatuck Historical Society, document the impact, aftermath, and recovery from these floods, as well as newspaper coverage from the time. The 1955 floods remain a defining moment in the town’s history, symbolizing resilience in the face of disaster.
