High Line Canal
The High Line Canal (HLC) is a man-made waterway, used for irrigation and recreation, that serves the Denver-Aurora Metropolitan Area. It begins at a diversion dam on the South Platte River, some 1.8 miles (2.9 km) above the mouth of Waterton Canyon. From its headgate, the HLC runs 66 miles (106 km) (historically 71 miles) to Green Valley Ranch, passing through Douglas, Arapahoe, Denver, and Adams Counties.

The High Line Canal is not the only one so named. Others in Colorado include the Farmer’s High Line (which flows from Golden passing through Westminster and Thornton); the Government High Line (which irrigates Grand Junction and the surrounding Grand Valley); and the Rocky Ford High Line (which irrigates land in the Arkansas River Valley around Boone, Fowler, Manzanola, and Rocky Ford). Elsewhere in Colorado and in other western states, there are a number of additional canals named "High Line" or "Highline".
