There's nothing like a fisheries biologist to clear up a few myths about the trout in your favorite stream. In this episode, we interview Driftless fisheries biologist Kirk Olson, who is lucky enough to work in four of the top trout fishing counties in southwestern Wisconsin: Monroe, Vernon, La Crosse, and Crawford counties, with more than 1,300 classified miles of trout streams. We cover topics like the problem of brown trout eclipsing brook trout in many streams, perpetual leases, and what percentage of the fish population the river kills each year.
