Construction and evaluation of salmonid habitat improvements on Fish Creek, a tributary of the upper Clackamas River, was continued in fiscal year 1985 by the Estacada Ranger District, Mt. Hood National Forest, and the Anadromous Fish Habitat Research Unit of the Pacific Northwest Forest and Range Experiment Station (PNW), USDA Forest Service. The study began in 1982 when PNW entered into an agreement with the Mt. Hood National Forest to evaluate fish habitat improvements in the Fish Creek basin on the Estacada Ranger District. The project was initially conceived as a 5-year effort (19824986) to be financed by Forest Service funds. Several factors limiting production of salmonids in the basin were identified during the first year of the study, and the scope of the habitat improvement effort was subsequently enlarged. The habitat improvement program and the evaluation of improvements were both expanded in mid-1983 when the Bonneville Power Administration entered into an agreement with the Mt. Hood National Forest to provide additional funding for work on Fish Creek. Habitat improvement work in the basin is designed to increase the annual number of chinook and coho salmon, and steelhead trout smolt outmigrants. The primary objectives of the evaluation include the: (1) Evaluation and quantification of changes in salmonid spawning and rearing habitat resulting from a variety of habitat Improvements. (2) Evaluation and quantification of changes in fish populations and biomass resulting from habitat improvements. (3) Evaluation of the cost-effectiveness of habitat improvements developed with BPA and Forest Service funds on Fish Creek. Several prototype enhancement projects were constructed and tested during the first three years of the study. The Intention was to identify successful techniques that could then be broadly applied within the bash. This stepwise procedure has been largely successful in identifying the most promising enhancement techniques for the Fish Creek basin. To date, 7-10 percent of the habitat area in the basin has been treated. When work on Fish Creek is completed, it is estimated that 50-60 percent of the total habitat area used by anadromous salmonids will have received some form of treatment. This annual progress report will focus on the projects completed in the basin In 1983, 1984, and 1985, and their evaluation. Winter habitat use and coho salmon and steelhead trout smolt production will also be emphasized.
