Sometimes natural disasters can block fish like salmon, steelhead and lamprey and keep them from getting upstream to spawn. But human development has lopped off thousands of miles of good spawning and rearing habitat over time. In this episode, we talk to ODFW biologists Greg Apke and Kenny Loffink, both of whom have worked in ODFW's Fish Passage and Fish Screening programs, about those programs and how they've worked with public advisors to solve some of the biggest problems that keep fish from reaching the best habitat.
