The sediment chart below is a brief on the 20 million (20,000,000!) cubic yards of sediment debris captured behind the four Klamath River dams that will be released with dam removal.
On October 20, 2011, at a Department of Interior (DOI) event, Oregon Senator Doug Whitsett stated for public record that the Federal Energy Commission estimated that 20,000,000 cubic yards has accumulated behind the four dams. The draft Environmental Impact Statement does not appear to mitigate 20,000,000 cubic yards of sediment.
*That amount of sediment is equal to approximately 2,000,000 ten yard dump truck loads of silt, sediment and organic muck not to mention possible hazardous levels of Chromium-6as found in the recent dam removal on the Rogue River in Southern Oregon!
Said chart indicates the possible damages in a profile graph regarding the potential depth of the sediment debris that will effect the anadromous fish and salmon egg redds spawning habitat on the Klamath River from River Mile 190 (RM) (about 6 feet in depth) at Iron Gate Dam, to the Pacific Ocean, RM 00 (at a depth of about 0.5 feet) if and when the proposed dams are breached.
