Our Klamath Basin
Water Crisis
Upholding rural Americans' rights to grow food,
own property, and caretake our wildlife and natural resources.
Response by Marcia Armstrong, Siskiyou County Supervisor
The analysis I referred to was done by our
consultants Stuart Miner of Brownfield Partners and John Lambie
of E-Pur. They were not of my own creation. According to our
consultants, the 2006 Klamath River Dam and Sediment Study was
not comprehensive, nor did it detail negative impacts. In fact,
it listed a large group of additional studies that would need to
be done to develop that information. The American Rivers study
did not use the accepted and vetted engineering model (HEC-RAS)
for sediment transport, nor did it use available detailed
topographic reservoir profiles. The model they did use accounted
for sand sized sediment, when the majority is silt sized. The
study is questionable. The studies done by the California State
Coastal Conservancy relied on the defective American Rivers
study. They failed to take into account that no study had been
done on how the flows will carry the sediment.
A review of sediment bore samples showed some presence of ethylbenzene and creosote compounds. Three bore samples taken in each of the reservoirs indicated that the sediment contains dioxin. Two samples were above human health standards. (You can read about that toxin and its carcinogenic health impacts here http://www.ejnet.org/dioxin/. ) It is likely that the levels of dioxin could kill the benthic community or bottom ecology of the river and that a large quantity of floating organic toxic waste particles would pollute the mouth of the estuary.
