Thank you to outgoing Chapter Chair Dorene McCoy ( and Secretary-Treasurer Francine Mejia (  We want to extend our gratitude to Dorene and Francine for their leadership and service to SFS, the Chapter, and our aquatic resources during an important transition period for the Chapter.

Please welcome incoming Chair Robert Danehy and Secretary-Treasurer Chris Zell!

Chapter Chair - Robert Danehy

Bob Danehy is an aquatic biologist who has worked in lakes and streams.  Most recently he has focused on forest and stream relationships and their influence on instream biota.  Research interests include biological diversity, headwater system ecology, and fish bioenergetics.  Bob is currently working in paired watershed, road erosion, and disturbance recovery studies in the PNW.  He earned a Ph.D. at SUNY ESF, Syracuse, NY.

Secretary/Treasurer - Chris Zell

Chris recently transitioned into the Regional Monitoring and Biocriteria Coordinator position(s) in EPA’s Office of Environmental Review and Assessment in Seattle. Chris is a professional hydrologist with more than 17 years of experience in reviewing, performing, and managing Clean Water Act related investigations across state, private, and federal settings. His technical interests and experiences occupy the nexus of aquatic ecology, hydrology, mathematical modeling, and statistics. Chris completed his undergraduate degree in Biology with a focus in Fisheries and Environmental Management from South Dakota State University and Master’s degree in Water Resources from the University of Missouri.

Membership Goal

This chapter is a transition from the Northwest Biological Assessment Workgroup which was a collaborative effort between State, Federal, Tribal agency, academic, and private industry founded in 1990. Membership is open to anyone who is interested in freshwater biotic communities and their role in aquatic ecosystems in the Pacific Northwest (generally, but not limited to: British Columbia, Idaho, Oregon, Washington, and Northern California).

Mission Statement

The purpose of the Pacific Northwest Chapter is to promote better understanding of the biotic communities in freshwater aquatic ecosystems of the Pacific Northwest. The chapter encourages and facilitates the use of benthic macroinvertebrates and fish assemblages and other biota in the assessment of the condition of freshwater aquatic resources and other environmental and natural resource management decision-making.
