Question: The Goodnough Dike is on the southeastern end of a reservoir that was built between what years?

Context paragraphs:
Sudbury Dam Historic District: The Sudbury Dam Historic District is a historic district on the southeastern end of Sudbury Reservoir off MA 30 in Framingham and Southborough, Massachusetts.  The district encompasses the Sudbury Dam (also known as the Fayville Dam for the nearby neighborhood of Southborough), which impounds the reservoir, and an area encompassing several historic structures located below the dam.  The area includes water-supply-related structures from three phases of development of the Greater Boston water supply system.  It was listed on the National Register of Historic Places in 1990.

Goodnough Dike: The Goodnough Dike (actually a dam) is on the southeastern end of the Quabbin Reservoir, the largest water body in Massachusetts.  It impounds the waters of Beaver Brook and therefore closes that exit to the Chicopee River Watershed.  The Goodnough Dike is not as large as the Winsor Dam, but it is equally important as they both trap the waters of the Quabbin Reservoir.  This dam is part of the metropolitan Boston's water supply, maintained by the Massachusetts Water Resources Authority.

X. Henry Goodnough: X. Henry Goodnough, (1860–1935), engineer, was chairman of Boston's Metropolitan Water District in the 1920s and chief advocate for creation of the Quabbin Reservoir project.  Goodnough Dike was named for him. .

Frank E. Winsor: Frank E. Winsor, civil engineer, was the chief engineer for the Boston Metropolitan District Water Supply Commission, now the Massachusetts Water Resources Authority, from 1926 until his death in 1939 and was closely involved in the design and construction of Winsor Dam and Goodnough Dike which were built by the Commission to create the Quabbin Reservoir in Massachusetts.  Winsor Dam was named for him.

Winsor Dam: The Winsor Dam and the Goodnough Dike impound the waters of the Swift River and the Ware River Diversion forming the Quabbin Reservoir, the largest water body in Massachusetts.  According to the Massachusetts Department of Conservation and Recreation the Winsor Dam is one of the largest dams in the Eastern U.S.  The Winsor Dam is part of the Chicopee River Watershed.  The Winsor Dam was named for Frank E. Winsor, its chief engineer.

Quabbin Reservoir: The Quabbin Reservoir is the largest inland body of water in the Commonwealth of Massachusetts and was built between 1930 and 1939.  Today along with the Wachusett Reservoir, it is the primary water supply for Boston, some 65 mi to the east, as well as 40 other communities in Greater Boston.  It also supplies water to three towns west of the reservoir and acts as backup supply for three others.  It has an aggregate capacity of 412 e9USgal and an area of 38.6 square miles (99.9 km²).

Lake Steilacoom: Lake Steilacoom is a reservoir approximately 4 km (2.5 mi) southwest of Tacoma in Pierce County, Washington, United States.  Its boundaries lie entirely within the city of Lakewood, Washington.  The reservoir covers approximately 306 acre , has a mean depth of 11 ft and a maximum depth of 20 ft .  Lake Steilacoom is a freshwater lake and drains into Puget Sound via Chambers Creek, which begins at its northern tip.  The lake is fed at its southeastern end by two creeks: Ponce de Leon Creek, which originates in springs below what is now Lakewood Towne Center, as well as Clover Creek which flows from its source near Frederickson to the lake.

Hillview Reservoir: The Hillview Reservoir is a 90 acre storage reservoir in southeastern Yonkers, New York.  It was built within a six-year period from 1909–1915 by the New York City Board of Water Supply to receive water from the newly constructed Catskill Aqueduct, which drained water from the Ashokan Reservoir and sent it down into the Kensico Reservoir, where it would, in turn, be drained back into the Catskill Aqueduct, and sent into the Hillview Reservoir.  Frank E. Winsor was the engineer in charge of construction of both Hillview and Kensico as well as 32 mi of the Catskill Aqueduct.

Simpson Ground Reservoir: Simpson Ground Reservoir is a reservoir in Cumbria, England, near the southeastern end of Lake Windermere.  It is located within a Forestry Commission conifer plantation, to the east of Staveley-in-Cartmel and provides fresh water supply for Grange-Over-Sands and the Haweswater aqueduct to Barrow.  The reservoir, which covers an area of 6.89 ha , was established in 1957.  The reservoir, at an altitude of 193 m , measures 455 x , and hs a capacity of 44 million gallons.  A plaque near the bank commemorates the opening of the reservoir on May 4, 1957, at the time by the Lancashire County Council.

Framingham Reservoir No. 3 Dam and Gatehouse: The Framingham Reservoir No. 3 Dam and Gatehouse is a historic waterworks facility in Framingham, Massachusetts.  The dam and gatehouse are located at the southeastern end of Framingham Reservoir No. 3, off Massachusetts Route 9.  They were built 1876–78 as part of an expansion of the public water supply of the city of Boston.  The dam is 2280 ft long, and impounds an area of 253 acre in the Sudbury River watershed.  The reservoir is the largest of the three Framingham reservoirs that were built at that time.  The dam's core is constructed of granite rubble laid in cement.  There is a granite-lined overfall area 100 ft long, which was originally topped by flashboards.  At the end of the overfall area nearest Route 9 stands the gatehouse, a granite structure with a rectangular main block and a smaller wing.  Both sections have a steeply pitched slate roof.  The door is in a round-arch recess, and the building is capped by a cupola.  It houses controls for two 4 ft mains connected to the Sudbury Aqueduct via the gatehouse at Reservoir No. 1.  The water is directed either directly beyond the dam into reservoir 1 or through the 4-foot mains to the Sudbury Aqueduct gatehouse.
