24-676: The plaques and signs at the site in the Quabbin Reservoir reservation. Frank E. Winsor was chief engineer of the Board from 1926 until his death in 1939 and as such was deeply involved in the design construction of Goodnough Dike as well as Winsor Dam and Quabbin Reservoir The Quabbin Reservoir is one of the largest fabricated public water supplies in the United States .
