Hickory Creek - Joliet: Corcoran Park to S.Joliet Street (3.75 miles) (IL)
Downstream of the dam, the width of the river is compressed as it heads toward a railroad bridge. At higher flows a fine surfable wave occurs before the flow piles into a bridge-pier.
Downstream of the railroad (again, at high flows) water swirls and boils in a deep pool. Whirling vortex currents appear and dissipate.
