Comments:   DPD05 consists of a 30-foot high dam with a fish ladder running up its face (DPD05Top) and four weirs downstream (DPD05Bot) that raise the channel. The weirs are partial barriers because each rises one to two feet above the water level and is 2-feet wide at the top. The fish ladder jump pools are 5-feet long, which can be short depending on the fish species and size. The fish ladder’s jump heights are also tall at 1.2 feet. The landowner is interested in working with the council and the Oregon Department of Fish and Wildlife to improve the barrier as much as possible.
