Book excerpt: The Bonneville Power Administration (BPA) is proposing to fund activities that will improve fish passage at Salmon River East Fork diversion 12 and at Herd Creek diversion 1. These projects represent cooperative efforts between the Custer Soil and Water Conservation District, Idaho Department of Fish and Game, and local irrigators. The goal of the SEF 12 project is to improve fish passage and habitat by removing the existing SEF 12 pushup gravel diversion, replacing it with a permanent rock weir structure, and installing an impervious membrane and geotextile liner in the wing diversion parallel to the stream bank. The work on the diversion structure at HC 1 will be confined to the existing headgate, wasteway and plunge pool immediately below the structure. The wasteway and plunge pool are part of the system that provides fish passage around the existing diversion structure. The new structure will include improved stop logs and a reconstructed plunge pool, which will enhance fish passage at the diversion.
