RedactedNarrative: On 3/31/12 at approx 1826hrs i was disptched to an accident of saguaro lake. Upon arrival to the aid station i noticed a large 35 foot watercraft tied up to the mcso dock with people standing on the dock waving me over. There was a female inside the watercraft lying on her back in obvious pain. I spoke to the female who told me the following: she and her husband along with a friend were heading back to the boat ramp when another watercraft turned into them striking the rear of her watercraft. She was sitting in the passenger seat and thrown into the drivers seat injuring her shoulder. Her husband was operating the watercraft and their friend was seated in the rear seat. I noticed a obvious deformity to the females left clavicle. Rural metro arrived on scene and began treatment. She was then trasnported by ground ambulance to the hospital. 
  
  I spoke with Operator2 who told me the following: he was operating the watercraft and was heading to the boat ramp as they were done with their outing for the day. They were approaching skink wash heading west. They noticed a watercraft leaving the shoreline heading in the same direction off their starboard side. The watercraft, v1, was approx 150 yard in front of them traveling at a slower speed. As they approached v1 and were over taking it on the starboard side, v1 made a sudden port turn without any warning, Operator2 tried to avoid a collision by turning his watercraft left but v1 struck v2 on the starboard rear corner of the transom. This caused v2 to spin around and threw his wife into his drivers seat. V1 did not turn around and look or make any audible signal prior to making the turn. Operator2 said that the damage to his watercraft was so severe it started taking on water so they put to shore at skunk creek wash were another boater picked them up and brought them to the aid station. V1 was located near boat ramp 2. Contact was made of the operator and occupants which lead tot the arrest of the operator for oui. At approx 2049 hours we went to skunk creek wash and investigated the damage to v2. The damage was consistant to what Operator2 had said happened. Photos were taken of both vessels and put into evidence. Case cleared by arrest. No further information.
