Hinckley Reservoir serves water to 130,000 people in the Greater Utica, New York area. The reservoir is located in the towns of Russia in Herkimer County, and Remsen in Oneida County. The reservoir, known by the name of the village near which it is situated, Hinckley, New York is about twenty miles north of Utica, New York in the foot-hills of the Adirondack Mountains. The topography of its watershed of 372 square miles is rugged and varies in altitude from about 1,165 to 3,100 feet above sea-level. The drainage basin of this creek, like that of the upper Mohawk, is located in the region which has the maximum precipitation of the state, a precipitation which is exceptionally high during the winter months, in the form of snow. No constricted gorge, where a short dam might be built, was available on the site of this reservoir. The dam has a total length of 3,700 feet, of which there is a 400-foot masonry section, embodying gate chambers and spillway. The major, or earthen, portion of the dam has a concrete core wall running through most of its length. The masonry content of the dam is 110,020 cubic yards, while there are 611,200 cubic yards of embankment in the earthen section. The masonry has a maximum height of 82 feet above rock and the overfall at the spillway is 61 feet. The maximum height of the earthen dam is 56 feet above the natural surface. The reservoir forks into two parts, which have a combined length of about thirteen miles but no great width, only about a half mile. Its area is 4.46 square miles and its capacity 3,445,000,000 cubic feet. The maximum depth at crest level is 75 feet and the average depth, 28 feet. It necessitated the removal of 209 buildings, which made up parts of three villages, and it submerged seven miles of highways. This reservoir too is of much value for flood regulation, the maximum rate of flood discharge being very materially reduced.〔(Whiteford 1921 Chap 24 )〕 Gregory B. Jarvis Plant is named in honor of the 41-year-old payload specialist from the Mohawk Valley who was killed aboard the Space Shuttle Challenger in 1986. This 9,000-kW facility began operation in June of that year. The power plant, containing two turbine-generators, is part of state-owned Hinckley Reservoir, which straddles Oneida and Herkimer counties. It is located about 20 miles from Mohawk Central High School, where Jarvis graduated in 1963.〔(www.nypa.gov )〕 == Geography == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hinckley Reservoir」の詳細全文を読む スポンサード リンク
