Scope/Content: Abstract: There are four dams on the Klamath River located between river miles 196 and 225 that are under consideration for removal: Iron Gate, Copco 1 and 2, and J.C. Boyle. Preliminary analyses indicate that there are approximately 15 to 21 million cubic yards of sediment stored within the reservoirs impounded by these four dams (Eilers and Gubala 2003, GEC 2006), most of which is silt and clay. Currently proposed dam removal options would result in up to four million cubic yards of that material being eroded into downstream reaches of the Klamath River, resulting in high suspended sediment loads and possibly localized short-term sediment deposition, both of which will have deleterious effects on aquatic habitats and species. The Conservancy has asked Stillwater Sciences to examine alternative drawdown periods, and select a biologically optimum period for beginning reservoir drawdown.
