East Slope Water Distribution
Colorado-Big Thompson Project water travels through the 13.1-mile Alva B. Adams Tunnel beneath Rocky Mountain National Park and exits the tunnel’s East Portal. It passes through a distribution system of reservoirs, canals, pipelines and five hydroelectric power plants.
About 895,000 people live within Northern Water boundaries, which encompass 1.6 million acres in portions of eight counties: Boulder, Broomfield, Larimer, Logan, Morgan, Sedgwick, Washington and Weld.
Northern Water provides cities, towns, rural-domestic water districts and industries with year-round deliveries.
Between April and October, the primary growing season, Northern Water also delivers water to more than 120 ditch, reservoir and irrigation companies serving thousands of farms and more than 640,000 acres.
