FISHWAY/FISH-BEARING STATUSA migration barrier to salmon, Dolly Varden, bull trout, and steehead is located within the diversion reach. In the 6-m falls upstream of the barrier there are resident rainbow trout and cutthroat trout. These fish are able to travel above and below the intake via the fishway.

ü Sockeye salmon ü Chum salmon ü Steelhead trout

FISH HABITAT ENHANCEMENT PROJECTIn collaboration with Fisheries and Oceans Canada, a network of fish habitat enhancement areas was constructed in 2007 downstream of the facility, at the confluence of Ashlu Creek and the Squamish River. The construction of three ponds – Hawkeye pond, Steelhead pond, and Pink pond – as well as surrounding riparian vegetation enhances the existing habitat that was rehabilitated in 1997. Species present in the 58,852 m² fish habitat enhancement areas include pink salmon, coho salmon, rainbow trout, and steelhead trout.

LONG-TERM MONITORING PROGRAMAshlu's five-year long-term monitoring program began in 2010 and includes monitoring of valued components such as riparian vegetation, water quality and temperature, fish community, invertebrate drift, wildlife and species at risk, habitat compensation and fishway effectiveness. A fish ladder was installed at the facility's intake in order to provide safe passage upstream past

the intake weir for gravid rainbow trout during spawning periods. Results of the fish passage evaluation show that both adult and juvenile rainbow trout can successfully migrate upstream through the fishway.For some of Ashlu Creek's long-term monitoring plan components, we are working in collaboration with local non-profit organizations: • The Squamish River Watershed Society is a

registered charitable organization focused on holistic solutions for watershed management within the Sea-to-Sky corridor. They work specifically on ensuring that all the facility's enhancement works are functioning as intended and undertake any necessary maintenance to ensure all intake works, side channels, wood structures, bridges, channels, and ponds are operating appropriately.

• The Sea-to-Sky Invasive Species Council is a non-profit society that works to minimize the negative impacts caused by invasive species on the south coast of British Columbia. They work to prevent the colonization of invasive species within our site, and prevent the spread of those invasive species that are found by conducting regular manual removals.

Environment

EconomyThe Ashlu Creek facility represents property, plant and equipment costs of approximately $139 million. It produces an average of 265,000 MWh of electricity annually, enough to power 24,000 British Columbia households. It generates annual revenues of approximately $18 million, and annual earnings before interest, taxes, depreciation, and amortization of approximately $15 million (based on average annual production).

Society

FIRST NATIONSThe Ashlu Creek hydroelectric facility lies within the asserted traditional territory of the Squamish First Nation. An impact and benefit agreement was executed with the Nation in 2005.

LOCAL COMMUNITYThe facility is located within Area D of the Squamish-Lillooet Regional District.

THE ASHLU CREEK FOUNDATIONThe commissioning of the Ashlu Creek facility in 2009 also marked the launch of the Ashlu Creek Foundation. This non-profit organization was established to support residents living in the remote region of Upper Squamish Valley. Its purpose is to enhance these residents' welfare and quality of life. Innergex made an initial donation of $400,000 to the Foundation and has committed to making annual donations of $80,000 for 20 years. In 2015, the Foundation brought high speed Wi-Fi Internet access to local residents.

KAYAKINGAshlu Creek is a swift river-like creek with several big rapids and large drops, making it a popular kayaking location. As agreed during the project's development and later specified in the Navigable Waters Protection Act approval, 12 flow-release weekends are made available each year – four in May and eight in August and September. Via the Innergex website, kayakers can request a flow release of 16 to 32 m3/s and enjoy a predictable and steady water flow. Outside of flow-release weekends, real-time creek flow data is provided on the Innergex website for kayakers to use in planning their outings.
