Project DescriptionThis project is located at the confluence of the North Fork and main stem of the Big Thompson River near the Town of Drake. The 2013 flood event produced large deposits of sediment and debris which completely blocked the US 34 bridge, and damaged private and public infrastructure from roadways to hotels, homes, and campgrounds. Restoring immediate access to this confluence of roads and waterways was a top priority after the flood, but emergency measures executed without a holistic vision left the reach severely degraded and in need of significant additional investment to repair. The North Fork Project consisted of sediment and debris removal to improve capacity of the river to accommodate higher flows; streambank stabilization and sediment redirection using innovative bioengineering techniques (engineering with rock and logs) along riverbanks, beds, and floodplain; and river habitat enhancement through native plant revegetation and habitat complexity installation. This project was completed in 2017 after an expedited construction timeline of just 87 days!
