Carrying Platte River water to Denver used to be the function of this canal between Waterton Canyon and Aurora, crossing several counties on its way. Now, a 71-mile trail, said to be accessible for most of its length, follows the same path. I traversed 5 miles of it on All Saints' Day, 2018. I saw water in parts of it, and mile markers 6 through 3, but no other information about the history of the canal or trail. I don't even know if I reached the start of the trail, although I did come to a parking lot and no accessible trail beyond that. Still, I consider it a good start.
