Bedload Transport on the Kootenai River near Bonners Ferry, ID (Part 3)
An underwater video camera was mounted on a Helley-Smith bedload sampler and set on the bottom of the river during a flow of around 32,000 cubic feet per second (bankfull). The video was titled with the GPS coordinates, date, and time.
Part 3 was recorded downstream of the Kootenai River's confluence with Fry Creek. It shows how backwater from the downstream Kootenay Lake affects sediment transport.
