Louisville Water Company opened the Crescent Hill Reservoir in December 1879 after crews removed tons of dirt and rock to create a 110-million gallon basin that allowed sediment to settle from Ohio River water. Its most notable feature is the Gatehouse, which controlled the rush of water in and out of the reservoir. Chief Engineer Charles Hermany chose a Gothic ornamental design, and urns at each corner of the roof denote the flow of water. After the reservoir opened, the Louisville Water Company president said the facility would be a pleasant place of attraction to visitors. Today the reservoir and Gatehouse are one of Louisville’s most tranquil landmarks.
