"Flood of 1955". In August 1955, two large storms passed over Litchfield County in close succession, flooding many local river valleys. North of Washington Depot, twin culverts carrying the Shepaug River under U.S. Route 202 were plugged with debris, causing floodwaters to accumulate upstream. The culverts and roadway succumbed to the resulting pressure, causing a wall of water to race down the river valley, washing away many of the homes and businesses in the Depot's village center, and killing a couple who ignored warnings to evacuate. A reconstruction effort, led by Henry B. Van Sinderen, and modeled after a town on Long Island, was quickly commenced. Homes and businesses soon reemerged, but the village lost many historic structures, and it has never regained its pre-flood density or vitality. The layout and visual character of the Depot were also radically altered, and the village center assumed its contemporary appearance, which varies considerably from Washington's traditional architectural vernacular.
