Abstract
The water storage of logs is widely practiced in the Pacific Northwest. An investigation has been made to determine the effect of this practice on water quality. Soluble organic matter and some inorganics leach from logs floating in water and from logs held in sprinkled land decks. The character and quantity of leachate from Douglas fir, ponderosa pine and hemlock logs have been examined. Measurements including BOD, COD, PBI, solids and toxicity have shown that in most situations the contribution of soluble leachates to holding water is not a significant water pollution problem. The most significant problem associated with water storage appears to be the loss of bark from logs during dumping, raft transport and raft storage. (Author Modified Abstract)
