Post-Wildfire Watershed Restoration and Recovery#

In 2020, the City’s water supplies were severely impacted by the Cameron Peak and East Troublesome wildfires. These two wildfires are considered the two largest in Colorado history, raising significant concerns about both the availability and quality of our future raw water supplies.

Due to the scale and severity of the burn areas, impacts to our raw water supplies are expected to be long-term.

As we come into spring and summer months, hot temperatures drive higher water demands and runoff from the burned areas can impact water supplies. With this knowledge, we are actively monitoring water quality and availability to ensure the highest quality water possible for our customers.

Assessments and modeling have been completed to identify highest priority areas for watershed recovery. With this information, the initial design of aerial mulching and other sediment and erosion control projects to stabilize hillslopes was developed.

In 2021, 5,050 acres of high-priority acres in the Poudre River watershed were mulched. We anticipate aerial mulching and ground erosion control projects to continue beginning June 2022, as funding allows.

Burn Scar Tour Results in Funding Recommendationhighlight_off

Secretary of Agriculture Tom Vilsack, Gov. Jared Polis, Sen. Bennett, Rep. Joe Neguse and others surveyed the destruction caused by the Cameron Peak Fire Friday, May 7. During the visit, speakers from several organizations provided information regarding the various needs for post-fire recovery and restoration.

Water providers, including Fort Collins Utilities, City of Greeley and Northern Water, advocated for additional funding to help address watershed restoration priorities to protect water supplies. Funding watershed stabilization measures early after the fire helps reduce the need for the more expensive work of removing ash and sediment from the river, sedimentation basins and intake facilities later on.

Following the visit, Gov. Polis recommended an additional $15M to the Colorado Water Conservation Board's Watershed Restoration Grant program, bringing the new total to $30M. This increase is reflected in the current Senate Bill SB-240, which will soon go before the House Appropriation Committee.

Cameron Peak Wildfire Water Quality Monitoring and Recovery Planhighlight_off

The Cameron Peak Wildfire Water Quality Monitoring and Recovery Plan was completed in early April. This plan provides a summary of water quality monitoring, analyses and reporting that Fort Collins Utilities and/or our regional partners will conduct in the Upper Poudre River watershed during the recovery phase of the Cameron Peak Fire. Water quality in the Upper Poudre River watershed will be monitored via the Upper Cache la Poudre Water Quality Monitoring Program, the Source Water Quality Surveillance and Response System (SRS), Storm/Precipitation Event Sampling and through several research studies.

Upper Cache la Poudre Water Quality Monitoring Programhighlight_off

In April, the Upper Cache la Poudre Water Quality Monitoring Program kicked off its fourteenth year of monitoring water quality in the Upper Poudre Watershed. This program helps the City and its partners, City of Greeley and Solider Canyon Drinking Water Authority, track short- and long-term trends in the Poudre River drinking water supply.

We are grateful to have two seasonal Watershed Technicians to help support this effort. Water samples collected as part of this program will be analyzed by the Water Quality Laboratory.  The Watershed Program will provide seasonal updates throughout the monitoring season to inform our partners, customers, and other community stakeholders about the condition of our source watershed and the quality of the raw drinking water supply.   

Source Water Quality Surveillance and Response Systemhighlight_off

The Source Water Quality Surveillance and Response System was deployed in early April.  There are two locations in the Poudre River upstream of our drinking water intake that provide near real-time water quality data.

This system will provide water treatment operations adequate warning time to quickly respond to changes in Poudre River water quality from ash, sediment and debris. Both sites have already proved to be valuable in detecting post-fire impacts from the Cameron Peak Fire during snowmelt runoff. Maintaining and operating this system is a collaborative effort between the Watershed Program and Stormwater Division. 

Post-Fire Research and Special Studieshighlight_off

Over the first quarter of 2021, the Watershed Program led a series of workshops focused on aligning several post-fire research studies with existing water quality monitoring programs and identifying partners and funding opportunities. This effort led to a regional partnership between the cities of Fort Collins, Greeley and Thornton, Northern Water, US Forest Service (USFS) Rocky Mountain Research Station, and the Coalition for the Poudre River Watershed. Over $100K in funding, analytical and staffing support for these studies was leveraged and committed to the studies. The following studies are being supported by this funding and are currently underway:

  • Predicting Post Wildfire Nutrients, Pollutants and Ash Delivery after the Cameron Peak Fire with WEPP Watershed Technology - P. Robichaud USFS Rocky Mountain Research Station, Moscow, Idaho
  • Quantifying Ash Mass, Chemical Composition and Delivery to the Poudre River Watershed after the Cameron Peak Fire – Chuck Rhoades, USFS Rocky Mountain Research Station, Fort Collins, Colorado
  • The effects of post-wildfire pollution on algal blooms in high mountain water supply reservoirs of the Poudre River Watershed – Matt Ross, Associate Professor, Colorado State University and FC Utilities Watershed Program

Watershed Program staff also helped lead the development of a smoke-related wildfire compounds special study as part of the Compounds of Emerging Concern Collaborative Water Quality Monitoring Program. This study will focus on developing methods and determining concentrations of smoke-related compounds at locations throughout the east slope CBT system, the Poudre River and other source water sites of interest. 

The overarching goal of these studies is to not only advance post-fire science but also further our understanding of source water quality impacts from the Cameron Peak Fire and develop strategies for management.

FireForest: An Exploration of Forest Fire and Restoration in Northern Coloradohighlight_off

Fort Collins Utilities is also collaborating and supporting a visual storytelling project called “FireForest.” The goal of this project is to use digital multimedia to communicate wildfire impacts to the Poudre River and its watershed and illustrate the importance of forest restoration on promoting forest health and resiliency. 

This will be accomplished through the use of digital photo essays, time-lapse photography, repeat photography and storytelling. The project is being led by Evan Barrientos Multimedia and is being collaboratively funded and supported by the City of Fort Collins Watershed Program, Coalition for the Poudre River Watershed, Northern Colorado Fireshed Collaborative, the Mighty Arrow Family Foundation and the Platte Basin Time-Lapse Project.  The Watershed Program contributed $1,500 toward this project to support the immediate need of installing a time-lapse camera on the Poudre River near the Poudre River Fish Hatchery.

Frequently Asked Questions#

What is the collaborative process and who are we collaborating with?highlight_off

We are coordinating with the Coalition for the Poudre River Watershed, the City of Greeley, Larimer County, the Natural Resources Conservation Service, the U.S. Forest Service, non-profit watershed groups and other water providers on watershed recovery and restoration efforts to reduce post-wildfire erosion and improve the health of the watershed.

This collaborative process is critical to:

  • maintaining the high quality of our raw water supplies
  • protecting our water supply infrastructure
  • maintaining continuity of our water treatment operations
  • supporting the overall health of the watershed
Why perform watershed recovery and restoration?highlight_off

The goal of post-wildfire watershed recovery and restoration is to mitigate the negative consequences of the wildfire to high priority watershed values, including water quality and supply, river ecosystem function and health, and to reduce flood impacts to downstream communities in both the Cache la Poudre and Big Thompson watersheds.

What does watershed restoration and recovery look like?highlight_off

Post-wildfire watershed recovery and restoration efforts are performed both on the ground and in the air. 

Ground operations include  structure protection and flood control projects on private
lands, as well as reservoir protection projects.

Aerial application techniques make it possible to apply mulches more efficiently and to treat inaccessible burned areas, making it a viable treatment alternative for the large fires that occur in the mountainous western U.S.

How are high-priority acres identified?highlight_off

High priority project areas were identified using science-based information and modeling, as well as collaborative data input from partners of the Larimer Recovery Collaborative. Aerial mulching is part of a larger program of recovery work intended to provide holistic post-fire mitigation on a total of 20,000 acres in high-priority sub-drainages in the Cameron Peak burn scar.
