Spanish Creek Tributary Culvert Replacement 7000 Road Objectives To replace a series of culverts that are acting as a barrier to fish movement and to reduce the risk of sediment delivery to Spanish Creek. FRBC Region/ MELP Region/ MoF Region Cariboo-Chilcotin/Cariboo/Cariboo Author Ken MacKenzie Proponent Weldwood of Canada Ltd. 100 Mile House Operations Location The site is located at 31 km on the 7000 Road just south of Spanish Lake and west of Wells Gray Park on an unnamed tributary to Spanish Creek. Introduction This stream is one of the main tributaries to upper Spanish Creek and has relatively high densities of rainbow trout downstream of the culverts. Assessments and Prescriptions This site was listed as the highest priority crossing for restoration in the Deception/Spanish watershed in the Boss-Deception fish passage-culvert inspection report. 4 culverts existed at the crossing all of which were barriers to fish passage due to high flow velocities and outfall drops (fig. 4-1). The site was a potential sediment source as well due to high flows and insufficient culvert capacity. The 10 meter width of the stream required that a clear span structure be used to provide fish passage and accommodate spring flow volumes. Rehabilitation Work
