Borthwick Creek Road Bridge Site Objectives To replace man-made barriers to fish with a clear span structure. FRBC Region/ MELP Region/ MoF Region Cariboo-Chilcotin/Cariboo/Cariboo Author Ken MacKenzie Proponent Weldwood of Canada Ltd. Location The site is located at 0.5 km on the Borthwick Creek Road in the Eagle Creek watershed. The unnamed stream flows into Oie Creek. Introduction Rainbow trout are abundant in the steam as well as a variety of non-game species. Assessments and Prescriptions The fish passage-culvert inspection report for the Eagle Creek watershed identified this site as the highest priority for restoration for a number of reasons. Habitat potential was listed as high, the culverts were acting as a total barrier to fish passage and a large amount of upstream habitat was isolated. Two culverts at the site had water velocities of 1.5 m/s and outfall drops of 25 cm (fig. 8-1). The width of the stream and quantity of spring flow required that a bridge be prescribed to allow fish passage at the crossing. Rehabilitation Work
