Dr. Jerri Bartholomew (OSU Microbiology) collaborated on a fish health monitoring program with the Bureau of Reclamation that combined water sampling, inverterate collection and "sentinel" fish exposures to inform real-time river management decisions.  The Klamath River spans the Oregon/California border and flows west into the Pacific Ocean.  It is an important habitat for salmonids.  Several pathogens impact the chinook and coho salmon populations.   Spatial and temporal data on occurrence of fish pathogens  facilitates model development, guides management decisions, and guides risk assessments.
