Grand County Secures Historic Water Right to Support Colorado River Flows
A historic water right is taking on a new role in Grand County - helping protect the Colorado River while supporting agriculture, recreation, and the environment.
Water has always been an important part of life in Colorado, and as communities continue to balance growing demands with changing water conditions, creative solutions are becoming increasingly valuable.
Grand County can now call upon a historic water right to help increase flows in the Colorado River through a new agreement with Northern Water. The agreement allows the county to release up to 10,000 acre-feet of water annually from the Colorado-Big Thompson Project—equivalent to approximately 3.3 billion gallons.
Helping the Colorado River During Critical Conditions
The water is intended to be used during periods when river flows are low and temperatures are high. These conditions can put additional stress on the Colorado River and the aquatic ecosystems that depend on it.
Releasing additional water during these periods can help cool the river and improve conditions for aquatic life, including fish and other species that rely on healthy river flows.
The benefits don't stop with the environment. Additional river flows can also support agricultural and recreational needs, making this agreement important for both the natural resources and communities connected to the river.
How Much Water Will Be Released?
Although the agreement allows for up to 10,000 acre-feet of water to be released in a year, that doesn't mean the full amount will be used every year.
The amount released will depend on conditions such as snowpack, water availability, and storage levels. Based on current expectations, average annual releases are anticipated to be around 5,000 acre-feet.
This flexible approach allows the water to be used when it can provide the greatest benefit while taking into account the broader needs of the Colorado-Big Thompson system.
A Water Right With a Long History
What makes this agreement particularly interesting is the history behind the water right.
The water was originally used to irrigate hay fields near Granby, supporting local agriculture. Later, a planned development that would have used the water did not move forward.
The water eventually became part of the Colorado-Big Thompson Project, where it remained stored for more than two decades.
Now, that same water resource is being given a new purpose.
Rather than simply remaining stored, it can be strategically used to help maintain healthier conditions in the Colorado River when the river needs additional flows most.
Collaboration for Colorado's Water Future
The agreement between Grand County and Northern Water highlights the importance of collaboration when it comes to managing Colorado's water resources.
Water management in the state often requires balancing many competing needs - from farms and ranches to growing communities, recreation, and the health of rivers and wildlife.
By finding a way to use an existing historic water right to address some of these needs, Grand County is creating an opportunity for that resource to benefit both people and the environment.
What This Could Mean for the Future
Colorado's rivers are an essential part of the state's landscape, economy, and way of life. As conditions change and water becomes an increasingly important issue, agreements like this can play a role in building greater flexibility and resilience.
Grand County's historic water right is now more than a piece of Colorado's water history. It has become a tool that can be used to support the health of the Colorado River, aquatic life, agriculture, and recreation.
It's a good example of how a water resource originally intended for one purpose can evolve over time - and how collaboration can help communities make the most of the water resources they already have.
For Grand County and the Colorado River, this agreement represents a meaningful step toward balancing today's needs while protecting the river for the years ahead.
