The Big Thompson Watershed Coalition (BTWC) formed as a 501(c)3 to help private and public landowners collaborate recovery efforts after the 2013 state-declared flooding emergency. Our flood recovery efforts brought over $15 million instate, federal, and local funds to the watershed allowing us to complete 15 restoration projects and 2 infrastructure replacement projects. Today, we are focused on creating a bright future for the Big Thompson watershed. Through dedicated partnerships we work to build resilience in the watershed through projects that reduce the risk and potential impacts of natural disasters like floods and wildfires and continue to help the watershed recover from events like the Cameron Peak Fire. Our goal as a Watershed Coalition is to bolster the health and integrity of this critical river system for the wild and natural communities that depend on it through engaging watershed residents and completing on-the-ground conservation projects.
