Water Patrol Officer(WPO) and Conservation Officer(CO) were driving on the East side of Lake Manawa when notified by Pottawattamie County Dispatch that there was an occurrence involving two Personal Watercrafts (PWC's) on Lake Manawa by the Country Club on the North side of Lake Manawa.  WPO and CO arrived at the County Club boat ramp, where Operator 1 and Operator 2 were waiting for them.  Operator 1's PWC was pulled out of the water and Operator 2's PWC was still in the water when the officers arrived.  Operator 1 and Operator 2 were driving in the same direction, when Operator 1 turned right to avoid the wake of a boat that passed perpendicular to them.  Operator 1 completed a 180 degree turn to avoid a collision with the passing vessel, while Operator 2 remained going in the same direction of travel.  Operator 2 struck Operator 1 with a head on collision.  There was substantial damage to both hulls of the PWC's.  The hull of Operator 2s PWC had a large hole at the bow and Operator 1's PWC had damage to the hull, and the sides of the vessel.
