The Colorado-Big Thompson Project 

The Colorado-Big Thompson Project collects and delivers on average more than 200,000 acre-feet of water each year. Here is a video snapshot of the history and operations of the Colorado-Big Thompson Project - a system of reservoirs, tunnels and canals that carries West Slope water across the Continental Divide to bring supplemental supplies to more than 1 million residents and 615,000 irrigated acres in Northern Colorado.
