an annual monitoring log is required from each dredging operation and discharges. Dredging operations of old simply placed a dredge on top of an area that was thought to have gold and strip-mined the area until nothing remained. As the dredge worked, it continuously dug into its own pond in front and filled it in with tailings at the back. The first successful dredging operation in the United States started at Bannock, Mont., in 1895. Oregon has always allowed suction dredge gold mining on its rivers. After its completion, the pond was filled with the 8-10 feet of water needed to float and operate the 988 ton dredge. Sometimes it took a whole day to load just one truck with some of the pieces needed to build the dredge.Īnother trucking company delivered the twenty-five pontoons, each measuring 10x10x27 feet, by hauling them over Galena Summit, no small feat. One of the largest loads was the 55-foot, 17.5 ton spud.
Some pieces were shipped by rail to Mackay and trucked there by Lindberg’s Trucking Company of Mackay to the Yankee Fork site over Spar Canyon Road. It was a major operation to transport the equipment and pieces needed to build the dredge. Trapped by increasing labour costs, shrinking gravel reserves and the fixed price of gold, Yukon Consolidated Gold Corporation shuts Dredge No.4 down.
