Project Summary
This project refurbished an old, outdated irrigation diversion, which diverts water from Mill Creek and serves the Caldwell Ditch east of Cove, Oregon. Mill Creek is a substantial tributary of Catherine Creek. Steelhead and chinook salmon have traditionally spawned upstream of the project site. The old diversion was an unsound structure constructed of concrete and wood. The diversion did not allow for juvenile fish passage, especially during low flows. This project reconstructed and reinforced the diversion and headgate structures, and installed an aluminum fishway. The new structure was designed to allow for bedload movement and prevent build-up of trash and bedload in front of the fishway to aid fish passage and to improve the operation of the diversion structure.
