Colorado Trout Unlimited works to protect, conserve and restore Colorado’s coldwater fisheries and their watersheds. As the grassroots arm of our parent organization, Trout Unlimited, we use cooperation, collaboration, advocacy and education to promote conservation.

A Strategic Approach to Fish and River Conservation

Founded in 1969, Colorado TU is the state’s leading non-profit, non-partisan organization providing a voice for Colorado’s rivers. As the financially self-sustaining, grassroots, Colorado-based arm of the national organization Trout Unlimited, Colorado TU is independently governed by a 37-member volunteer board.

collin-papuga-youth-campColorado TU leverages the power of its 11,000 members from 24 chapters across Colorado who contribute approximately 44,000 volunteer hours annually to restoration, education and other local conservation projects, equivalent to the power of 22 full-time employees.

Our vision is simple – by the next generation, Colorado TU will ensure that robust populations of native and wild coldwater fish once again thrive within their original Colorado range so that our children can enjoy healthy fisheries in their home waters.

Colorado TU works to:

  • Protect high quality habitat for native and wild coldwater fish and to maintain free flowing rivers;
  • Reconnect fragmented fish populations and habitats by restoring flows to dewatered rivers and re-opening fish passage;
  • Restore watersheds by working in collaboration with other conservation and governmental organizations, as well as private landowners, to preserve and improve the quality of habitats that support coldwater fish;
  • Sustain the efforts of our volunteers and supporters by inspiring a strong conservation ethic in the next generation of river stewards.

Colorado TU Strategies:

  • Grassroots engagement;
  • Support for on-the-ground community-led projects and initiatives;
  • Advocacy at the national, state and local levels;
  • Collaboration and partnerships with private landowners, state, federal and local agencies, and other key stakeholders;
  • Use of local knowledge as well as science-based tools like TU’s Conservation Success Index to help develop, prioritize and initiate conservation efforts and advocacy;
  • Leverage resources committed by donors and increase capacity through the efforts of our volunteers;
  • Education and outreach to Colorado’s young people, providing hands-on, field-based opportunities that foster awareness for the connections between Colorado’s trout, water resources, the environment and themselves.
