Woodjam Creek Culvert Access Objectives To restore fish passage at this mainstem culvert crossing for all life stages of the target species. FRBC Region/ MELP Region/ MoF Region Cariboo/Cariboo/Cariboo Author Michael Parker Proponent Weldwood of Canada Ltd., Williams Lake Division Watershed Woodjam Creek Location Woodjam Creek is a tributary to the Horsefly River. A wide range of species including anadromous species utilize the majority of this watershed that is located approximately 25 km East of the community of Horsefly, in the Horsefly Forest District. Introduction This project was undertaken to address concerns within the proponents operating area as identified through an assessment conducted by another licensee. As WRP is meant to be conducted on the watershed scale it often does addresses issues for more than one operator, and as such operators in this case chose to address identified projects individually. Assessments and Prescriptions Minimal Assessments have been conducted in this watershed on fish or riparian habitat. However, a Fish Passage Culvert Inspection was completed in 1998 by Bioterra Consulting for Riverside Forest Products, Soda Creek Division. As part of this watershed is in the operating area of Weldwood of Canada Ltd., this firm proceeded with the replacement of the one high priority identified barrier within their area of the watershed. This replacement provides access to 3.6 km of high value fish habitat, not including tributaries above this mainstem crossing. The existing culvert was determined to be undersized for the crossing according to Forest Practices Code requirements as the 1400mm culvert was not adequate for high flows on the 2.3m bankfull channel. It is expected that velocities impact adult migration during spawning periods, as well as juvenile passage. Rehabilitation Work The old 1400mm culvert was replaced with a full spanning bridge structure. Fill was pulled back and the channel around the bridge abutments armoured. Gradient through this area was approximately 1.5%. Cost Summary
*budget is estimated based on similar project activities at other locations. Restoration Results Over 3.6 km of mainstem habitat is now accessible to all life stages of fish. As well, tributaries above the crossing will be accessible from the mainstem for rearing. The mainstem itself is approximately 2.3 meters bankfull at the crossing, and provides a variety of rearing and spawning upstream of the crossing. Proposed Work Level 1 FHAP Assessment and in stream works are scheduled to begin in Woodjam Creek during 1999. For Further Information contact: Brian Chapman Or Karen Campbell
