High Line Canal, Mouth of South Platte River to confluence with Second Creek, Denver, Denver County, CO

Significance: The first major irrigation project on the Front Range, it was the largest and most expensive canal ever built in Colorado before the advent of transmontane water diversion. Also called the "English" Canal because of the nationality of its original sponsors, the High Line project demonstrates the integral role of foreign investors in Colorado's development. although it promoted settlement in and around Denver during the late 19th century, the canal never achieved the success its investors had expected. Nevertheless, the canal is presently an important part of Denver's urban fabric.
