50 years of protecting rivers and we're just getting started.

Founded in 1969, Colorado TU is the state’s leading non-profit, non-partisan organization providing a voice for Colorado’s rivers and trout. As the financially self-sustaining, grassroots, Colorado-based arm of the national organization Trout Unlimited, Colorado TU leverages the power of its 11,000 members from 24 chapters across Colorado who contribute approximately 44,000 volunteer hours each year.
