The tunnel is 18 1/4 miles long, 11 feet 6 inches high, 10 feet 3 inches wide, passes 2630 feet below Balsam Mountain, and has a carrying capacity of 600 million gallons daily. Construction of the Catskill Water System began in 1907, and water from the Ashokan Reservoir came in 1915. The Shandaken Tunnel and Gilboa Dam were begun in 1917. Water was first delivered through this tunnel on February 9, 1924, and the Gilboa Dam was completed in 1926. This site is 22 miles south of the Gilboa Dam and 137 miles north of the Silver Lake Reservoir on Staten Island.
