Which canal is longer, the Central Arizona Project or the Sacramento Deep Water Ship Channel?
Central Arizona Project The Central Arizona Project (CAP) is a 336 mi (541 km) diversion canal in Arizona in the United States. The aqueduct diverts water from the Colorado River from the Bill Williams Wildlife Refuge south portion of Lake Havasu near Parker into central and southern Arizona. The CAP is the second largest and expansive aqueduct system ever constructed in the United States. CAP is managed and operated by the Central Arizona Water Conservation District (CAWCD). It was shepherded through Congress by Carl Hayden.
Alva B. Adams Tunnel The Alva B. Adams Tunnel is the principal component of the largest transmountain water project in Colorado, the Colorado-Big Thompson Project (C-BT). The tunnel transfers water from the western slope of the Colorado River drainage to the eastern Front Range of Colorado. The tunnel is 13.1 mi long and has a concrete lined diameter of 9.75 ft . The tunnel drops 109 ft in elevation along its length and runs in a straight line under the Continental Divide from west to east passing under Rocky Mountain National Park. At its deepest point, the tunnel is about 3,800 ft below the surface of the mountain peaks. Construction began on 15 June 1940, but was suspended as a result of World War II priorities, from the end of 1942 to August 1943. The tunnel was holed through on 31 March 1944, an event that was broadcast throughout the United States by NBC Radio. The tunnel was posthumously named for its chief advocate, US Senator Alva B. Adams.
