From its sparkling headwaters
in Rocky Mountain National Park to its confluence with the South Platte, the Big Thompson watershed provides the water we drink, the food we grow, the wood we harvest, the fishing and wildlife habitat we enjoy, and the beauty we treasure. Whether you are a resident within the watershed, a downstream water user, or one of millions who visit and explore the Big Thompson River every year, this waterway holds special value to the livelihoods and lifestyles of those connected to it.
Trek the Thompson is a free community celebration of the Big Thompson River and watershed located along the Big T River at Fairgrounds Park. The event features interactive education stations where community members and watershed visitors can learn about the river, watersheds, wildlife, recreation, and all that the Big T provides for Northern Colorado. This year’s Trek the Thompson will also be in remembrance of the 10th anniversary of the 2013 floods and the amazing amount of collaborative recovery work that has happened since.
In addition to interactive education stations, attendees can also enjoy live music from local bands, participate in a free prize raffle, enjoy food from local food trucks, and join us on our newly introduced “treks” to go birding, ID native plants, and learn about our river system.
So, bring your kids, dogs, and friends and join us to celebrate one of Loveland’s most treasured resources!

Remembering the 2013 Flood

Fairgrounds Park flood impacts

Big T Canyon Mountain post-flood

Namaqua Ave flood impacts
On September 9th, 2013, exactly 10 years before Trek the Thompson, a five-day rain event began which brought 15-20 inches of rain to the watershed and led to a 100-year flood event in the Big Thompson and much of the Front Range. Flood waters were funneled down the Big Thompson Canyon destroying the river channel, roads and infrastructure, homes, and much of the land around the river. The flood claimed two lives in the Big Thompson and six more statewide, led 13 counties to declare a state of emergency, and in total left a wake of damage estimated at over $2 billion statewide. In the aftermath of this disastrous event, community members, landowners, and local organizations came together to collaborate on flood recovery efforts. The need for recovery efforts also led to the creation of the Big Thompson Watershed Coalition. Over the last 10 years tens of millions of dollars have been brough to the watershed to fund collaborative recovery efforts involving BTWC, private landowners, the County, CO Dept. of Transportation, and many more partners. These recovery efforts have worked to not only restore the system but to make it more resilient to future flood events. We are proud to be a part of these efforts and want to take this 10th anniversary to not only remember the flood and the lives it took but also to recognize the incredible work that has been done to rebuild and reshape our watershed.
