South Fork Rock Creek Dam existing condition. RDG completed a fishway design for the site.
|  | RDG assisted the Marys River Watershed Council and the City of Corvallis with design and installation of four stream simulation culverts and two fish ladders to improve stream connectivity in the Rock Creek watershed near Corvallis. The stream simulation culverts replace fish passage barriers that restricted cutthroat trout movement. The two concrete fish ladders were retrofitted to two water intake structures on tributaries to Rock Creek. Native cutthroat trout now have access to several miles of pristine habitat on the Siuslaw National Forest.
