- To reach its starting point, take Colorado 470 to Wadsworth (Colorado 121) and follow Colorado 121 south to Waterton Canyon’s parking lot.

FAQs
What agency should I contact with questions or concerns about the canal or trail?
The High Line Canal Conservancy is a great resource for members of the public seeking information about the High Line Canal. Denver Water is responsible for running water through the canal and for completing general maintenance of the canal. There are also stormwater agencies that maintain sections of the canal where stormwater management systems have been put into place. Denver Water has agreements with seven local recreation agencies that are responsible for maintaining the trail and managing recreation:
- Douglas County Parks and Trails
- Metro District of Highlands Ranch Parks and Open Space
- South Suburban Parks and Recreation
- Greenwood Village Parks, Trails and Recreation Department
- Cherry Hills Village Parks, Trails and Recreation Division
- Denver Parks and Recreation
- Aurora Parks, Open Space & Trails

When does water flow in the canal?
The canal has an 1879 water right, which is fairly junior by Colorado water rights standards. Depending on the availability of water from the South Platte River, and irrigation demand by users on the canal, Denver Water intermittently runs water through the canal between the months of April and October.
Does the canal have seepage?
All dirt-lined canals seep water. The canal seeps about 60 to 80 percent of the water running through it, making it more suitable for recreation purposes than for water delivery. The canal has been seeping since it opened more than a century ago. Denver Water understands some people who have built below the canal may have problems with normal seepage loss from the canal, but it is not the responsibility of Denver Water, or its partnering agencies, to correct those problems. The canal was in operation — and leaking — at its present location long before development in areas near the canal.
