Many scientists and water management agencies believe climate change may bring greater extremes in weather events including more intense storm-related flooding and more frequent and severe droughts. With this in mind the BC Conservation Foundation, in partnership with Fisheries & Oceans Canada and the Ministry of Environment undertook a retrofit project at the Cameron Lake Weir located at the outlet of Cameron Lake on Vancouver Island.

The purpose of the project was to increase the water storage capacity of Cameron Lake by upgrading the existing weir located at the outlet of the lake, (the headwaters of Little Qualicum River on Vancouver Island, BC). The stored water will be used by fisheries managers to augment flows in the river during the dry summer and early fall seasons to improve hydraulic conditions and productivity of freshwater fish habitats.
The project entailed installing an aluminum fishway and flow control valve at the weir, and lowering the channel invert upstream and downstream of the weir to improve access to existing licensed water storage and enable access to potential new storage. Engineering design work took place from April to July 2006 and the project was constructed in August and September 2006. The total design and construction costs were $181,020.
Benefits of this project include improved access to Cameron Lake for juvenile trout via the fishway and increased flow in Little Qualicum River during the late summer and early fall seasons. Water discharged from storage will improve hydraulic conditions and productivity of freshwater fish habitats below the lake and above the anadromous barrier, as well as freshwater and anadromous habitats in the lower river. Additional flows will also aid upstream adult chum and chinook migrations in the early fall.
Project funding was provided by the Georgia Basin Living Rivers Program, Pacific Salmon
Commission - Southern Fund, and the BC Ministry of Transportation.
