Three small tributaries of Drift Creek, tributary to the Alsea River, Oregon, were monitored in this logging study (1959 to 1973). One watershed (Needle Branch) was clearcut without buffer strips. A second (Deer Creek) was clearcut in patches with buffer strips. The third (Flynn Creek) was unlogged, and served as a control.
A synthesis of the results from the original study is found in Moring and Lantz (1975), The Alsea Watershed Study: Effects of Logging on the Aquatic Resources of Three Headwater Streams of the Alsea River, Oregon:
Part I: Biological
Part II: Changes in Environmental Conditions
Part III: Discussion and Recommendations
