On June 4, 2011, at approximately 12:45PM Operator1 was operating his Champion boat northbound in Joyce's Slough on the Mississippi River in Clinton, IA.  At the same time, operator2 was operating his Crestliner boat eastbound with 3 passengers, when his motor failed (shut off).  boat1 was exiting the flood wall passageway as boat2 was entering and the two boats collided.  Information was exchanged and Operator1 contacted Lucas Webinger with the DNR.

Contributing factors that likely led to the incident was restricted vision of the operators by the flood wall, lack of power from operator2's boat and the relatively narrow entrance and exit of the flood wall passageway.
