This report describes the preliminary results of a study to compare effects of clear-cut and staggered logging on fish and other aquatic resources in small headwater streams. The results of this study were published in ODFW Fishery Research Report 9 in 3 parts.
Project AFS-58 Final Report (part 3). The final of three reports on a 15-year study to determine the effects of logging on the aquatic resources of three tributaries of the lower Alsea River. The study took place from 1959-1973. Primary objectives included in-depth study of population characteristics of fish species...

The lower Deschutes River of northcentral Oregon has a historically uniform discharge record. Significant reductions in discharge below the seasonal norms will degrade the environment for migratory and resident salmonids by increasing siltation and gravel compaction, and by reducing intragravel water dissolved oxygen content. Fish spawning will be limited by...
