RDG is working with stakeholders to improve fish passage for both resident and anadromous fish species. Projects in Oregon have focused on providing passage for steelhead, Chinook, endemic suckers, redband trout, and other native species. Montana fish passage projects typically involve improving passage for the State of Montana’s species of special concern westslope cutthroat trout, and the federally-threatened bull trout. RDG employs techniques including roughened channel, stream simulation, and fishway designs to correct fish passage limitations.
