Photo C1. Minor grading of the site was performed to remove field crowns and provide fill material for ditches on the site (Nov. 22,2002).

Photo C2. A section of channel excavated and ready for the installation of structures, transplants, and matting. The orange stakes mark the design top of banks (Dec. 2,2002).

yaoto YY. A meander bend or the restored channel after a bankfull event the night before. The outside of the meander bend shows no erosion due to the transplants that were placed there. The log vane structure is keeping the strongest velocities and energy near the center of the channel and away from the banks. Note the debris on the live stake in the foreground, indicating stream stage, and the deposition of sediment on the point bar (March 21,2003).
