This project involved the identification of 12 non-natural barriers (culverts) to fish passage on status roads within TFL 18 and 1site on FL #A18688. As part of the pre-field planning phase, potential culvert sites were selected mainly on the basis of local knowledge, combined with existing inventory data such as Fish Stream Identification (FSID), Fish Habitat Assessments (FHAP), and Fish and Fish Habitat Inventory (FFHI). As a result of the pre-field review, 13 culvert crossings were selected for further field assessment1. Twelve (12) crossings assessed were metal or plastic culvert structures on known or suspected fish streams and one (1) of the crossings assessed (Thuya Creek) was a wooden box culvert on an assumed or confirmed fish-stream.
