About BTWC

Our Story

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.

During the catastrophic flood of 2013, many of the ways people were connected to and benefited from the Big Thompson River were significantly impacted. Soon after the flood, the Big Thompson Watershed Coalition (BTWC) was formed as a 501(c)3 nonprofit organization to help private property owners and other groups collaborate over flood recovery and long-term improvements to the health of this treasured area, its wildlife and its communities.

Big Thompson River in the aftermath of the 2013 Flood

Our overarching objective is to foster resilience in the watershed by providing multi-purpose and multi-stakeholder benefits to water and forest resources, as well as the wildlife and people who depend on them. Since 2013 we have helped raise over $10 million dollars in federal, state, and local funds for river improvement projects, developed 3 large-scale river management and restoration plans, completed 10 major river enhancement projects, and worked with over 150 private landowners and organizations in the process.

The BTWC serves a unique function of bringing together private landowners, public land management and infrastructure agencies, agriculture, local business, and recreation and tourism industries and recognizes these individuals as key parts of the Big Thompson watershed’s unique identity, economy, and health. We appreciate the support of our community partners and look forward to continuing this important work in the future.

Big-T Fact: The Flood of 2013

Over 1 week in September 2013, 15-20 inches of rain fell across the watershed.

This one flood event:

  • Forced Larimer County (which incorporates the entire Big Thompson watershed) and 13 other Coloradoan counties to declare state of emergency

  • Claimed two lives in the Big Thompson and 6 more statewide

  • Damaged or destroyed 6,000 homes, 1,000 businesses, bridges, roadways, etc.

  • Eroded river banks and flushed soil downstream, leaving deposits up to 10ft deep in some places

  • Impaired substantial ecological, recreational, and economic resources 

  • Left a wake of damage estimated at over $2 billion state-wide

Big-T Fact: The start of the BTWC

The Big Thompson Watershed Coalition was started by a handful of volunteers who met in a local fly shop to take action on post-flood recovery!
