It was the city's original public water supply, built privately in 1883 by engineer Judson W. Warner, bought by the village in 1895 and expanded in 1905-06. It retains integrity from both building phases despite deterioration.","narrative":"Mount Hope Reservoir is a 64-acre site three miles south of downtown Oneida, New York, holding two dams, their valve houses and miles of wooded trails. The lower dam, an earthen structure with a concrete core, was built in 1883 by local engineer and industrialist Judson W. Warner as a private water works supplying drinking water, fire protection and industrial needs. The village bought the system in 1895. In 1905-06 a concrete gravity dam and second pond were added upstream to meet growing demand. The reservoir supplied Oneida until the larger Taberg Reservoir opened in 1927, after which it served for fishing, swimming, camping and hiking. The upper dam was later condemned for its poor condition, and the city largely abandoned the site in 1979. Concrete is spalled, and one gate house is in ruins. The site is valued as a public works achievement from the period when Oneida grew into a regional rail and manufacturing center.","period_of_significance":"1883-1906","architect_builder":"Judson W.
