About Colorado Trout Unlimited
Colorado Trout Unlimited (CTU) is the state council of Trout Unlimited, founded in 1969 and organized as a 501(c)(3) nonprofit. CTU coordinates 22 local chapters and thousands of volunteers across Colorado to protect, restore, and defend coldwater fisheries and their watersheds.
CTU combines on-the-ground habitat restoration, science-based advocacy, and education programs (including Trout in the Classroom and youth conservation camps). In recent years (2023–2025) CTU has expanded headwaters restoration projects, increased youth education recognition, and led statewide monitoring and response efforts for emerging threats such as invasive zebra mussels.
