River Projects

Glen Haven at West Creek and Fox Creek

Project Description

Three streams converge near Glen Haven, Colorado: Fox Creek, West Creek, and the North Fork of the Big Thompson River. The 2013 flood caused damage along all three stream corridors as floodwaters overflowed banks, swept trees and debris downstream, and destroyed many structures, bridges, culverts, and roads. BTWC led coordination with over 90 private properties along Fox and West Creeks to implement measures that reduce risk to property and infrastructure, while improving long-term stream resilience and wildlife habitat. The majority of the stream restoration work consisted of the removal of large sediment deposits brought downstream during the flood and the construction of floodplains that encourage connectivity between floodplains and their streams. Native plants and habitat elements for wildlife were also implemented as part of the project. These restoration techniques aim to reduce the water level and impact of floodwater and debris on local homes, infrastructure, and ecosystem.

Construction began in October 2016 and was completed in June 2017.

Get Involved

The BTWC continues to monitor creek conditions periodically to evaluate long-term success, and is working with partners at Larimer County to help manage noxious weeds present in small numbers in the area. Interested in helping monitor with BTWC staff or donating toward the ongoing monitoring and management?

Glen Haven

Before and After

Before (2013)

A channel avulsion, where the main creek channel jumped across the floodplain to a different location, created the “Grand Canyon of Fox Creek.” Note the lack of in-channel habitat and
floodplain connectivity to relieve flood energy.

After (2017)

Banks were graded back and planted for stabilization, reconnecting the channel with the floodplain and increasing the system’s overall discharge capacity and habitat quality.
