Horsetooth Reservoir Maintenance Project

Maintenance Work at Horsetooth Reservoir Complete

Update: Nov. 10, 2020

The Horsetooth Reservoir Maintenance Project is complete. Water delivery to users resumed on Thursday, Nov. 5, 2020, one week ahead of schedule.  

What was the Horsetooth Reservoir Maintenance Project?

Crews from Northern Water and the U.S. Bureau of Reclamation performed a maintenance project at Soldier Canyon Dam in the fall of 2020. To accomplish the work, water levels in Horsetooth Reservoir were decreased to levels not seen in several years. 

Through the summer and early fall of 2020, water was released to municipal, industrial and agricultural users as normal, but flows into the reservoir were halted. Normal releases of reservoir water met the needs of users while the reservoir was brought to a safe level for maintenance work. 

What was the construction period? 

Maintenance occured from October through November 2020. Following the completion of the work, inflows resumed to the reservoir and normal operations are anticipated for 2021. 

What did the project include? 

Routine maintenance including the replacement of valve seals on three valves in the Soldier Canyon Dam Outlet, as well as maintenance work to the reservoir itself. This project did not involve major construction. Other agencies also performed work during this time.  

How did this project affect recreation at Horsetooth Reservoir or neighboring communities? 

There were minimal to no impacts to recreational activities at the reservoir, including fishing, camping, hiking and the use of hand-launched watercraft.
