Poudre Flows: Collaboration to Protect the Cache la Poudre River

On October 14th, the Poudre Flows Project, a collaboration of Colorado Water Trust, the Colorado Water Conservation Board, Cache la Poudre Water Users Association, the cities of Fort Collins, Greeley, and Thornton, Northern Colorado Water Conservancy District, and Colorado Parks and Wildlife, began increasing flows in the Cache la Poudre River. During the week of October 14, Thornton added flows between the mouth of the Poudre River and the confluence with the South Platte.

The Poudre Flows Project aims to reconnect the Cache la Poudre River past numerous frequent dry-up locations between the mouth of the Poudre Canyon and the confluence with the South Platte River while still allowing water rights owners to use their water. Under a temporary plan approved by the State, water provided by the cities of Thornton and/or Greeley can be used in a trial run of the innovative Poudre Flows Project. As conditions allow, the temporary plan allows water provided by Thornton to be used to increase flows by up to 20 cubic feet per second (“cfs”) for up to two weeks this fall and again in the spring. As conditions allow, the plan will also allow water provided by Greeley to be used to increase flows between 3-5 cfs between the months of April to October.

“The Poudre Flows project has brought a cross section of water users and river advocates together to add and protect flows on the Poudre River,” said Emily Hunt, Deputy Utilities Director for the City of Thornton. “Thornton is proud to contribute the first deliveries of water in a trial run of this project and is excited to continue its work with the  Colorado Water Trust and the Poudre Flows partners to achieve significant environmental benefits for the Poudre River.”

The Poudre Flows Project implements a new mechanism known as a Streamflow Augmentation Plan that was approved by the Colorado legislature to help restore depleted river flows. Generally, an augmentation plan is a tool used by water users to increase flexibility and maximize utilization of water supplies on a stream while still protecting other water users. While augmentation plans are typically used to replace water diverted from the river to meet water use needs, the Poudre Flows Project uses this same tool to meet environmental needs by releasing water to the river and protecting it from diversion by others as it flows downstream.

“The Colorado Water Conservation Board is proud to be a part of this critical effort to protect flows on the Cache La Poudre River,” said Lauren Ris, CWCB Director. “Through our agency’s Instream Flow Program, we are able to ensure that the river maintains its vital flows, supporting both the environment and the communities that depend on it. This collaboration highlights the importance of innovative solutions to protect Colorado’s water for generations to come.”

Historically, environmentalists and recreationalists have been at odds with water users who take water out of the river. The Poudre Flows Project is bringing together those who have previously been in conflict, including municipalities, water conservancy districts, state agencies and agricultural producers. This group will strategically leverage water rights to preserve and improve river flows in times of low flow. The Poudre Flows Project has a pending water court case; but in the meantime, Greeley and Thornton have obtained temporary approvals in October from the Colorado Division of Water Resources, via substitute water supply plans, to use their water rights in the Streamflow Augmentation Plan for one year. This is the first Streamflow Augmentation Plan in the state and could be a model for streamflow improvement in other river basins.

“Greeley is excited to see the Poudre Flows project going live after many years of regional collaboration, enabling legislation, and investment in this innovative water administration strategy,” said Sean Chambers, Director of Water Utilities for the City of Greeley. “The project will physically enhance the Cache la Poudre river, its aquatic habitat, and the administration of water rights, and Greeley appreciates the Colorado Water Trust’s leadership and project management.”

THE POUDRE FLOWS STORY:
For more than a decade, the water community of the Poudre River Basin has been working on an innovative plan to reconnect one of the hardest working rivers in Colorado, the Cache la Poudre River. Since the Colorado gold rush in the mid-1800s, people have diverted water from the Cache la Poudre River for beneficial uses that have helped northeastern Colorado grow into the agricultural and industrial powerhouse it is today.

While the Poudre River flows are high during the spring runoff, there are times throughout the year when the river dries out entirely in places below some water-diversion structures. To combat dry conditions and improve river health, local communities have worked hard over the past decade with the goal of improving and bringing vitality to the Cache la Poudre River. The Poudre Flows Project is a perfect example of those efforts.

Colorado Water Trust, a statewide nonprofit organization with a mission to restore water to Colorado’s rivers, has been one small part of this process. Over a decade ago, Colorado Water Trust had an unorthodox, pioneering idea to reconnect the Poudre River, and the water community of the Poudre River Basin said, “Let’s get it done.” A broad collaboration of water providers, cities, state government, nonprofits, and a collective of farmers have worked tirelessly to make this novel idea a reality and rewater the Poudre River. Finally, this year, the Poudre Flows Project will be put into action through the generous contributions of water by the cities of Greeley and Thornton. This is the first step toward reconnecting the Poudre River both now and for future generations.

”The Poudre Flows Project is such a great example of collaboration and innovative thinking when it comes to water, and it shows a recognition of how important our streams are to us as Coloradans,” said Kate Ryan, Executive Director of Colorado Water Trust. “You have all different types of water users on the Poudre River coming together to take responsibility for the health and vitality of this river and to find ways to protect it for future generations. The success of this project could serve as a blueprint across the state for communities of water users to protect their own rivers and streams in the face of a changing climate.”

Colorado’s water landscape is very complex and the legal structure for this project is innovative. The Poudre Flows Project will provide water right owners a flexible opportunity to add their water to the plan on a temporary or permanent basis. This groundbreaking project has the potential to be replicated in other basins throughout Colorado. Lastly, one of the unique aspects of this project is that it doesn’t change the
Poudre River from being the hardest-working river in Colorado. Instead, the Poudre Flows Project provides an avenue for optimal management of river water, to protect people’s livelihoods AND the river itself. The Poudre Flows Project proves that if we work together, we can maintain all that we love about Colorado, from the beauty and thrills of a flowing river to the local food and beer that river water helps provide, and the flourishing neighborhoods that depend on the river’s water in their homes.

“Partnerships are the key ingredient to the success of the Poudre Flows Project,” said Katie Donahue, Director of the City of Fort Collins Natural Areas Department. “Together we are launching a new chapter of river resiliency for our community.”
