Coho salmon populations have been decreasing in number within the Siletz River for numerous years due to channelization from anthropogenic activities. As a restoration effort, over 500 logs were placed into log jam formations in three fish-bearing tributaries of the Siletz River in 2014. The introduction of the logs serves the purpose of slowing the water, stabilizing the stream bed structure, increasing stream complexity, and overall improving the quality of the habitat. Four objectives are in place to collectively investigate the long-term restoration effort’s success: 1) Assess the changes in available fish habitat, 2) Examine long-term topographic changes in the stream, 3) Investigate the movement and stability of the large wood, and 4) Investigate the relationship between the basin's geomorphology and fish populations. Multiple methods are required to fully evaluate the success of the restoration endeavor on the winter juvenile coho salmon population. They include: 1) Topographic surveys with a Nikon total station of the stream bed and banks to understand the geomorphology of the stream, 2) Pebble counts to quantify the sediment distribution, 3) Instrumented level loggers to continuously measure water surface elevations for varying discharges, 4) Simulating acceptable habitat, considering velocity and shear stress, with the hydraulic modeling program Nays2DH, and 5) Working alongside the Oregon Department of Fish and Wildlife to collect electrofishing, seining, and snorkeling fish surveys within the basin.
