The City of Colorado Springs obtained the water rights to these ditches and constructed the Hoosier Pass Tunnel to replace them as part of the Continental-Hoosier Diversion System. The 10 foot (3 m) diameter 1.5 mile (2.4 km) water tunnel was completed in 1951 and delivers up to 500 cubic feet per second (14.2m3/s) to the Montgomery Reservoir about a mile southwest of the pass, from which the water is piped 70 miles (113 km) to Colorado Springs. Average annual diversions through the tunnel have been on the order of 9000 acre feet (11 million m3).
