Mayo B Hydroelectrical Project
The Mayo B Hydroelectrical Enhancement Project, commissioned in 2011, has increased the capacity of the Mayo system to generate power from 5 megawatts to 15 megawatts without the need for a new dam. The project involved the construction of a new powerhouse and penstock as well as modification of Mayo River flow regimes to enhance the capacity for power generation, while retaining/enhancing salmon values in the river.
Our Role in the Project
- Baseline data collection including fish, invertebrates, water quality and terrestrial components
- Habitat mapping and modelling
- Mitigation and compensation design
- Impact Assessment assistance including YESAA submission and Water License and Fisheries Act authorization.
- Environmental Monitoring during construction including in-stream works as well as bird nesting surveys and timber salvage surveys along the penstock right-of-way prior to clearing.
- Design and construction oversight of a juvenile Chinook salmon-rearing channel downstream of the Mayo B tailrace (commissioned to 2012).
