Eastern Mojave Vegetation Welch Ditch, Jefferson County, Colorado  
 

Tom Schweich  

Home Page  The Welch Ditch, which first carried water in 1871, was constructed to supply water to Colorado School of Mines when the school was located at the current Lookout Mountain Youth Services Center. It was later extended as far as Smith Reservoir near the intersection of Kipling Park was and West Jewell Avenue.
 

Head Gate.

The plan is to install a suspension bridge from the head gate across to the Peaks to Plains Trail.
