Fish Screening Task Force

The ODFW Fish Screening Task Force was formed in 1991 (ORS 496.085) to advise the Department on screening program development, funding, monitoring, technology, reporting, and project prioritization. This seven person public body is composed of three members representing agriculture, three representing fishing/fish conservation, and one representing the public at large. This group provides the public a great opportunity to shape how the screen program operates. The task force meets quarterly throughout the state. Members are appointed by the ODFW Commission and may serve up to three consecutive two year terms. Current Task Force members and their terms are:
