In the area of the fuse plug, the force of the water created a new outlet stream channel, connecting to the original channel approximately 4,100 feet downstream of the former lake outlet. The released water caused erosion of the fuse plug, fuse plug foundation material, and spillway channel. In addition, erosion and deposition of eroded sediments occurred in selected downstream areas in the Dead River system. Please Note: PDF files require Acrobat Reader 5.0 or greater.
