Collection history

In August 1955, Connecticut’s rivers rose into streets, homes and factories. Rain from Connie had already soaked the ground when Diane brought another deluge. The National Weather Service’s account places the disaster across a network of valleys rather than at one single point. In communities such as Winsted and along the Naugatuck and Farmington rivers, familiar roads and crossings became scenes of destruction. [SGC101-S1]

The photographs show the collapse of ordinary connections. A missing bridge meant more than damaged steel or masonry: it separated people from homes, work and help. Flooded commercial streets place the water beside storefronts and intersections that residents knew by name. These views are strongest when their town and date stay attached, so an image of New Hartford is not passed off as Waterbury, and a Norwalk scene is not silently assigned to August. [SGC101-S2]

The year brought a second major emergency in October. Connecticut’s hazard history records renewed flooding on October 15–17. The Coast Guard view of Norwalk in this collection belongs to October 16. Together the August and October images explain why the phrase ‘the flood of ’55’ can refer to different memories in different towns. [SGC101-S2]

Local libraries and historical societies preserve many more views than any one selection can contain. The Derby and Naugatuck collections linked below allow visitors to follow recognizable streets and neighborhoods through the disaster. They extend the gallery while keeping each institution’s captions and photograph credits intact. [SGC101-S3]
