Yellowstone Fish Bypass Project

Lower Yellowstone Fish Bypass Project Set to Begin in June 2019
In November 2015, Thunderbird was selected to administer the Storm Water Pollution Prevention Plan (SWPPP) for a large weir and fish passage construction project on the Lower Yellowstone River in eastern Montana. The planned re-construction of a 100-year old weir, and construction of a new 2-mile long fish bypass channel is aimed at helping the endangered Pallid Sturgeon migrate upstream during its annual spawning season. The project which was delayed numerous times over the past four years has finally cleared all the legal hurdles in the federal court system and is set to begin later this month. Thunderbird will manage the SWPPP related tasks out of its satellite office in Glendive, Montana.
