Technical information
The dam was built 1933-38. Its width at the top is 35 ft ( 10.67 m) and 878 ft (267.61 m) at the bottom. It is 264 ft (80.47 m) above the bedrock and 135 ft (41.15 m) above Beaver Brook. There was 2.5 million cubic yards of fill used in the construction and the dam contains 31 caissons. The elevation is 540 ft (164.59 m) MSL.
History
The dam was named after
X. Henry Goodnough, who was chair of the Boston Metropolitan Water and Sewer Board during 1921. This dike is part of the Quabbin Reservoir facility. This dike is sometimes called the Quabbin Dike, however its name has never been changed from its original and, in fact, remains as originally named, imprinted on 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

. Four towns were flooded in the Swift River Valley. Construction of the reservoir remains a great engineering feat and Quabbin is one of the largest unfiltered water supplies in the world. The reservoir is 18 miles (28.96 km) long and has 181 miles (291.23 km) of shoreline including 61 miles (98.15 km) along the reservoir's 60 islands. Quabbin collects an average of one-half of the precipitation that falls on its watershed. When full, the reservoir holds about of water.
