The Cache La Poudre River defines the landscape of northern Colorado as it transitions from the Roosevelt National Forest into the agricultural valley. This 1962 survey, updated with 1970s aerial data, documents a complex network of water management essential to the region, including the North Poudre Supply Canal and the Pleasant Valley And Lake Canal. These engineering works support several bodies of water such as Seaman Reservoir and Miners Lake, which are central to the local irrigation and filtration infrastructure.
