Anderson Perry & Associates conducted an assessment of stream channel morphology, in-stream and ripaiarn habitat, and fish passage conditions on the Titus Creek stream reach that flows through the Walla Walla Community College, Walla Walla campus. A stream restoration plan was developed from baseline assessment data. Improvements that enhance the stream corridor, both in terms of hydrologic and habitat functions, as well as aesthetic values, were presented.

Innovative Stream Restoration Project on WWCC Campus



In early 2008, Walla Walla Community College was awarded a grant of $153,901.00 from the Snake River Salmon Recovery Board, Washington State Department of Recreation and Conservation Office.  The grant was to be used to abandon a shallow, cement pond; divert the water into the original natural channel; and improve fish passage and habitat on Titus Creek.  The creek has high potential as a rearing area for Endangered Species Act listed summer steelhead and spring Chinook; however, the pond heats water in this cold, spring-fed section of Titus Creek, a tributary to Mill Creek.  Diverting water back to a more natural waterway will result in lower water temperatures and improve water quality reaching Mill Creek.  The restored channel will be planted with in-stream habitat and native riparian plantings.


Titus Creek flows within 50 yards of the WWCC William A. Grant Water & Environmental Center and will provide a learning opportunity for future natural resource managers.  The final intent of the project is to propose a variety of habitat improvements on the WWCC campus and to develop a living lab for students and community members adjacent to the William A. Grant Water & Environmental Center.  The overall project goal is to develop a plan that will lead to a self-sustaining, stable, resilient stream channel, improving and increasing riparian and in-stream habitat diversity and improving passage for summer steelhead and spring Chinook salmon.


Anderson Perry & Associates were contracted to provide an initial habitat assessment and restoration plan for Titus Creek including existing morphology and proposed habitat improvements.  As part of the restoration plan Titus Creek is envisioned to be converted to a natural channel, with established in-stream habitat improvements and native riparian buffers.  An interdisciplinary team consisting of Washington Department of Fish and Wildlife, Confederated Tribes of the Umatilla Indian Reservation, US Army Corps of Engineers, and others were consulted throughout the planning project.
