First, our thanks to Milner Group for their donation of logs and stumps, to the Snuneymuxw First Nation and City of Nanaimo for help developing and carrying out this project, and to the Pacific Salmon Foundation for their support. The pamphlet below was developed to inform neighbors and other interested community members of the work plan. 
This was our first "big" project, requiring temporary diversion of the creek to install two large woody debris structures. Previously, boulders were hand placed and brush bundles were installed along the bank to prevent erosion. These were mostly washed out during extreme rainfall events. For this project, volunteers filled sandbags and helped set up coffer dams to temporarily exclude fish access to the creek. Biologists carried out electro-fishing to move any fish in the work area to a safe location (none were found at this site). Two pumps were set up to remove water and make sure water with stirred up sediment didn't re-enter the creek. A small excavator installed logs and stumps in the banks of the creek. These are just touching the surface of the water now (at very low flow) so that as the water rises the space under the large woody debris will be protected from the scouring effect of high flows, and offer sanctuary to fish. Large boulders were added to the streambed to force the water to meander downstream, creating smaller pools that slow flow and improve habitat.
Logs and stumps installed at the Morningside CWMN location, to create a pool and prevent bank erosion during high flows.  Huge stump and boulders installed between the Morningside CWMN location and the culvert under Morningside drive.
