New York Taps New Catskill Source
The Shandaken tunnel in the Catskills that was opened recently will carry a 250,000,000-gallon supply daily to New York through the present Catskill aqueduct after flowing ninety miles. The Shandaken tunnel which was constructed under the supervision of the New York Board of Water Supply and under the engineering direction of J. Waldo Smith and Thaddeus Merriman, consulting engineer and chief engineer of the hoard, respectively, is 95,740 feet long and said to be the longest in the world. Next to it in length is New York City’s pressure tunnel which carries the Catskill water underneath the city for a distance of 93,953 feet. Among other large tunnels are the Saint Gothard tunnel in the Alps, 49,147 feet in length and the Hoosac tunnel in Massachusetts which is 25,080 feet long.
The Schoharie Creek flows down the side of the Catskill Mountains into the Mohawk River, which in turn reached the Hudson opposite Troy. The Schoharie watershed has an area of 314 square miles to which is added a portion of the Esopus watershed of 257 square miles. The Schoharie water is impounded by a huge dam at Gilboa. The average depth of the Shandaken tunnel below the surface of the ground is 750 feet while the greatest depth is 2,200 feet. The tunnel is carried through rock for its engine length. About 10,000 employees were hired in the course of its construction and a permanent force of 1,500 men worked in three eight-hour shifts. The work was completed in less than three years almost a year sooner than the contract provided.
