NHC worked with Metro Vancouver to design and construct a nature-like fishway to replace an existing timber weir fishway at the 3-meter-high Cariboo Dam situated along the Brunette River. At the fishway inlet, three slotted weirs are used to limit the fishway flows over the range of expected upstream lake levels, allowing the fishway to operate unattended and providing suitable flows and passage hydraulics over varying hydrologic conditions. Downstream of the control weirs, a series of 12 boulder step-pool structures over a 25-meter-long section of channel were constructed within a 2.8-meter-wide concrete flume. The new fishway successfully improved access to Burnaby Lake for anadromous and resident fish. Chum salmon are now able to spawn in upper tributaries for the first time in 80 years.
