The replacement of the overflow dam involved several critical construction phases. The project began with concrete repairs to the existing dam core, followed by backfill entombment using rip rap for reinforcement. Bedrock excavation was completed to create a new riparian channel, ensuring improved water flow and structural stability. A new concrete stop log control structure was then built at the left abutment of the existing dam, along with abutment and wing walls to enhance durability. On the right side of the structure, a concrete core wall extension was erected. To further reinforce the structure, post-tensioned anchoring was implemented for the new control structure. Additional installations included a structural steel operation platform, a hoist system, wooden stop logs, and a permanent concrete bulkhead. Selective demolition of existing structures was also carried out as part of the overall redevelopment.

Located 169 kilometres southeast of Berens River First Nation, this project required extensive logistical planning and coordination. Executing construction in a northern environment posed unique challenges, including limited accessibility and extreme weather conditions. To navigate these obstacles, PCL engaged local labour while also housing PCL employees in nearby accommodations to ensure a steady workforce. 

PCL prioritized Indigenous participation throughout the project. Of the 16 direct-hire hourly employees, eight were Indigenous, representing a significant portion of the on-site workforce. Additionally, 24% of the total project cost was subcontracted to Indigenous-owned companies, reinforcing PCL’s commitment to supporting local communities. Concrete supply was sourced from Lafarge in Winnipeg, which provided a specialized retarder mix to allow for a five-hour placement time, ensuring efficient material use in a remote setting.
