Tahltan Lake Dam Repairs

The current condition of the existing weir and walkway structure cannot be repaired to extend its service life because the current design is not amenable to the operational and maintenance (O&M) that would bring it to an acceptable and dependable design standard. Due to the remote location of this site; routine O&M is not an obtainable nor practical part of life cycle management. The proposed new structure would have minimal O&M investment requirements. Alternative building materials such as wood and steel would require extensive corrosion and O&M investments.

Tahltan Lake supports significant sockeye lakeshore spawning, is culturally significant to the Tahltan Nation, and is an important location for DFO Stock Assessment. The project will support government-wide and Fisheries & Oceans objectives by showing the public and First Nation partners that there is a commitment to continue the work that the camp has been doing into the long-term future.
