Streams and Aquatic Life

Stream hydrology and aquatic research on the forests is largely conducted in and around Oak Creek. This stream is one of three major drainages on the McDonald Forests to the north and west of Corvallis and flows into the Mary’s River. The other two streams include Soap Creek and Jackson-Frazier Creeks. Hydrologic and aquatic research help inform land managers on best practices around water resource management and conservation to ensure protection of watersheds and of species relying on bodies of water for survival.
