Lower North Fork of the Big Thompson

The Big Thompson was devastated by the September, 2013 flood estimated to be a 500-year event (15,500 cfs at canyon mouth), as well as the subsequent post flood emergency road construction and infrastructure protection. Post-flood sampling found near complete loss of trout, sediment and habitat degradation throughout the reach. 

To achieve a successful project on the Lower North Fork of the Big Thompson River, Wildlands Restoration Volunteers, FlyWater, inc and EcoHydro implemented flood-plain reconnection, fisheries enhancement, soft armor/bioengineering slope stability and channel re-alignments where appropriate throughout a 2.5-mile reach of the Lower North Fork on the Big Thompson, across five different land-ownerships including state and county land. A mojor highlight of this multi-objective project was the successful removal an abandoned diversion dam. The removal of this in-stream fish barrier opened up the entire North Fork of the Big Thompson to the main stem of the Big Thompson River. This project further includes post-flood stream restoration focusing on aquatic and riparian habitat enhancement for trout, watershed resiliency measures
