Two subjects were underway on a Yamaha Wave Runner (PWC) about one eighth to one fourth miles from the sandbar in the back of Little Allison Creek heading in an east, southeast, direction towards the main body of Lake Wylie or towards the Ebenezer Park area. While enroute to unknown destination the PWC collided with a private dock/pier. Officer and myself were dispatched to the scene.
