Northern Water is a public agency created in 1937 to contract with the U.S. Bureau of Reclamation to build the Colorado-Big Thompson Project, which collects water on the West Slope and delivers it to the East Slope through a 13-mile tunnel that runs underneath Rocky Mountain National Park. Northern Water’s boundaries encompass portions of eight counties, 615,000 irrigated acres and a population of more than 1 million people. For more information, visit www.northernwater.org.
