Horsetooth Outlet Project (HOP) - Infrastructure Improvements

Horsetooth Reservoir

Did you know? Horsetooth Reservoir was built between 1946-1949 and holds up to 156,735 acre feet (51,072,250,000 gallons) of water.

 

The Horsetooth Outlet Project (HOP) is an important infrastructure maintenance project planned by Northern Water and the Bureau of Reclamation to repair and upgrade the Soldier Canyon Dam outlet this fall.

This outlet plays an important role in our daily lives by supplying water to more than 220,000 residents and businesses in Fort Collins and the surrounding areas.

To meet the needs of our community, all residential and commercial customers need to reduce water use to winter (indoor) levels earlier this year. There are many ways to save water; however, stopping outdoor water use is most effective. Learn more about outdoor water restrictions, which began Oct. 1.

Current HOP Status: Scheduled to begin in October. By moving forward with HOP this fall (if conditions continue to be safe to do so), we will be strengthening the Horsetooth Reservoir water delivery infrastructure for the future. The fire could affect water quality in the Poudre River for many future runoff seasons – which makes it even more important to complete the HOP maintenance now.

FAQs

How Are We Doing? Check Out Our Current Water Demand

The average historical water demand on Oct. 18 is 17.3 million gallons (MG). The current demand for Fort Collins Utilities water customers is 14.2 MG. Our goal during HOP is 15 MG. 

Thank you for your help reducing our water use! Please continue your good efforts so we can keep the numbers down.

In addition to Fort Collins Utilities, the Soldier Canyon Dam outlet supplies water to neighboring communities who receive their water from: 

All water districts impacted by HOP are asking customers to reduce water use during the project, with the main focus to stop outdoor water use on Oct 1. Check with your water district to learn more, if you are not a Fort Collins Utilities water customer.

How Will HOP Affect Our Community?

Fort Collins Utilities is fortunate to receive water from two sources: Horsetooth Reservoir and the Cache la Poudre River. However, during HOP, Utilities will rely on Poudre River water supply, making it even more important to ensure our water resources are used efficiently. 

Starting Oct. 1, we need your help using less water so we can get the most out of our water resources. 

The City is also doing its part by requiring all departments to stop non-essential water use. You might notice some park lawns and other areas go dormant a little early this year and dustier vehicles as we hold off on fleet car washing throughout HOP.

Calendar

When Will HOP Begin?

Work will begin in October and is expected to last 30-45 days, likely ending in early December (weather permitting). This timing was chosen to decrease impacts to customers and landscaping and allow time for the work to be completed before winter weather sets in. 

Prior to the start of HOP, Northern Water will gradually lower reservoir levels by releasing water to municipal, industrial and agricultural users as normal, but stopping flows into the reservoir. As a result, you may already see extended beach areas. Lower water levels will help workers accomplish their tasks more safely.

So, What Is An Outlet?

If you're wondering what an outlet is, you're not alone. To put it in simple terms, the outlet being repaired is the pipe that delivers water from Horsetooth Reservoir to our Water Treatment Facility and the Soldier Canyon Water Treatment Plant. It's a very valuable asset in delivering the water we drink, bathe in and use on our landscapes. 

There's a much more complicated answer that involves intake structures, conduit, control house gates, regulating gates, valves, gate chambers and stilling basins – all of which are located in a dam and are used to control water releases from a reservoir. 

What Are The Improvements?

This necessary and proactive maintenance project will help protect our infrastructure and water supplies into the future.

During the maintenance, crews will remove rust, recoat valves and replace rubber seals. Dive teams also will install new stainless steel trash racks to more efficiently prevent water-borne debris from passing through the outlet structure to the water treatment plants.

Help Save Water During HOP: Stop Outdoor Watering Oct. 1

Help Save Water During HOP: Stop Outdoor Watering Oct. 1

The best way to conserve water throughout HOP is by stopping outdoor water use Oct. 1 -- just a couple weeks earlier than usual this year.

 

Beginning Oct. 1, all residential and commercial customers need to stop outdoor water use

Exceptions include athletic/active fields for health and safety purposes and raw (untreated) and well water customers because this water is not affected by HOP. Examples include City parks, golf courses, cemeteries, The Gardens on Spring Creek, Colorado State University and schools, though we are all working together to save water.

We typically see a drop in water use by mid-October as temperatures cool and landscape watering ends for the season. On average, a Fort Collins' household uses 300 gallons less a day in the winter than during the summer months, with community-wide use averaging around 15 MGD compared to 40 MGD in the summer.

Fortunately, this is the tail end of the irrigation season, and depending on the weather, many systems are turned off and ready to be winterized by this time.

How Can I Help?

  • Stop outdoor water use Oct. 1.
  • Share this information with your neighbors, friends and family.
  • Water trees and shrubs deeply prior to Oct. 1 (and again following HOP, if needed).
  • Don't pressure wash or spray outdoor surfaces with hoses - use dry methods like sweeping and leaf blowers instead.
  • Place a 'Reduce Your Use' yard sign in your lawn to encourage others to do the same. Request a sign here
Recreation Icon

What Will the City Do?

  • Limit outdoor water use to athletic fields and areas necessary for public safety.
  • Maximize use of raw (untreated) water on landscapes.
  • Stop fleet vehicle washing unless approved for health and safety.
  • Only street sweep atrial and collector streets once a month.
