Lynn Creek Off-Channel

A collaboration between the BCIT Rivers Institute and the North Shore Streamkeepers with key involvement by the DNV and DFO to create a nursery for young salmon.

Problem & Scope

Off-channel habitat provides refuge for young salmonids during winter storms and summer droughts.

At this existing off-channel in Lynn Creek, near Inter River Park, low flows in summer led to young salmonids being stranded.

This site had been identified for enhancement in a study for the Ministry of Water, Land and Air Protection

North Shore Streamkeepers monitored water in the channel in 2017:

    • May 26: 200+ fry counted
    • July 8: Lower pools dry; no fry here
    • Sept 2: No water flow to large woody debris (LWD) pool
    • Sept 2: Volunteers moved 451 fry to the main creek

Aug 20, 2017 – Channel is dry, with isolated pools.

Planning & Research

  • Convert ephemeral channel to off-channel habitat.
  • Enhance 150m of existing habitat by installing 4 boulder/log complexes.
  • Engage young people through art.

Timeline

  • 2017 – Planning & engineering ($21,400)
  • 2018 – Field work (estimate: $78,849)
  • 2018 – August: In-stream structure construction
  • 2019 – Salmon habitat protective fencing and Community Art Project

Large woody debris and boulders are installed and secured in the Lynn Creek Off-Channel Habitat in August 2018.

After construction at LWD Complex #1 – August 2018.

After the first rains at LWD Complex #1 – September 2018.

In September 2019, a Community Art Project celebrates the Off-Channel Habitat.

The September 2019 Community Art Project was installed along the Off-Channel Habitat on protective fencing erected by the District of North Vancouver.
