The Trinity County Migration Barrier Removal Project at West Weaver Creek and Oregon Street replaced an undersized, perched culvert with a concrete, Con-Tech bottomless culvert. The arch provides for full natural stream bed simulation and the flood capacity at the crossing was designed for the 100-year storm, preventing future culvert blockages, flooding, and blow-outs. This project was funded through the CA Department of Fish and Game S.B. 271 Grant Program, Proposition 204, and Trinity County in-kind matching funds. Unfortunately, the old perched culvert had created quite a popular swimming hole!.
