high, and 10.5 feet above the outlet. The inner slope is riprapped with 

 loose rock extending 5 feet below the high-water line. The outlet is 

 12-inch vitrified pipe set in a concrete bulkhead at each end. The 

 gate is a common type of sliding iron gate. The reservoir was built 

 in 1908 and cost $930, or at the rate of $35 per acre-foot of capacity.

 of the Dealy farm is served by the Jackson Ditch, but a part lies 

 above this ditch and is commanded only by the Larimer County Canal
