gROS vENTRE rIVER

gRAND tETON naTIONAL paRK JACKSON, WY

Floods in 2016 eroded a significant portion of the stream-bank along the road between Jackson and Kelly WY. Emergency rip-rap dumps were made to stop the erosion however these were not engineered and needed to be stabilized. Clearwater Restoration partnered with Oftedal Construction, a heavy civil construction firm, to fix the road. We constructed a diversion channel to handle the full flow of the Gros Ventre River, stabilized the emergency rip-rap placements, added engineered barbs (natural channel design) to dissipate erosive flows, and restored pool habitats near the barbs. We also regraded the banks to a natural slope and planted willows in the rip-rap to further dissipate scouring flows and protect stream banks. 

PROJECT HIGHLIGHTS:

• 650' diversion  

• Salvaged trout, sculpin, and stone-flies from dewatered channel

• Diverted full flow of the Gros Ventre River for 30+ days. 

• Riparian revegitation in native soil and rip-rap
• Placed 500 tons of imported rip-rap

• Project Completion 2019
