RedactedNarrative: On 07/02/15 at approximately 1117 hours, Dep. responded to the above listed location on Coeur d’Alene Lake for a reported boat crash. While en route, I learned it was reported on Marine Channel 16. It was reported a barge had ran over a pontoon boat with five people in the water. Medical personnel were also dispatched. 
  
  Dep. and I arrived first. I observed a North Idaho Maritime tug boat pushing a large barge. The tug boat was named “Kelly Ann” and I later learned was a documented vessel through the United States Coast Guard (USCG). Everyone associated with the pontoon boat was accounted for and safe. I contacted the Kelly Ann's Captain O1.
  
  I walked to the bow of the barge and observed the pontoon boat, capsized under the starboard side of the barge. I observed damaged to one of the pontoons. From under water, I was able to observe the canopy was bent. Due to the position of the pontoon boat, I was unable to observe any further damage. 
  
  The barge had one large crane (detached) and one smaller crane (attached). Also on the barge were several metal pipes, several cinder blocks and a pike pole. Dep. assisted by photographing the scene. 
  
  I spoke with Operator1 and learned the following: Operator1 was not injured. passenger and he were heading to Silver Beach Marina from Cougar bay. He and V1 passenger had checked both sides of the vessel before heading out. They did not observe any vessels. Operator1 was operating the Kelly Ann and did not observe the pontoon boat until it was hit. Operator1 said he was traveling approximately six knots at the time of the crash. Operator1's captain license was in the process of being renewed with the USCG, but believed it had not expired yet. Dep. provided Operator1 IBARD paperwork to complete. 
  
  I spoke with V1 passenger and learned the following: V1 passenger was not injured. V1 passenger was working on the Kelly Ann. Prior to heading to Silver Beach Marina, he checked the route of travel. When V1 passenger did not observe any vessels in their path, he returned to the wheel house. V1 passenger remained in the wheel house up to the point of impact. V1 passenger did not observe the pontoon boat prior to impact. I later learned V1 passenger stated he had a current Captain's license. I contacted the USGC to confirm if V1 passenger did. They advised they would check and later advised if he did and if any endorsements were attached to the license. 
  
  I was contacted by Fire personnel and learned everyone on the pontoon boat refused medical treatment. Fire Personnel did not observe any signs of serious injury to the occupants. One person had a small cut to their hand. 
  
  I spoke with the pontoon boat owner/operator2. Operator2 had a small cut to his right hand, next to the thumb. I learned the following from Operator2: There were three other people aboard the pontoon boat. No one was on board the vessel prior to impact. They were all floating in the water, each with their own type four throw able. Operator2 did not see the barge until it was almost on top of them. Operator2 swam and boarded the pontoon boat in an attempt to move it. Because of the close distance, Operator2 was unsuccessful. The barge struck the pontoon boat and pulled Operator2 under water. After being under water for several seconds, Operator2 surfaced and was assisted to the Kelly Ann. Operator2 advised his boat was just floating and not at anchor. 
  
  According to v2 occupant, they were floating in the water for approximately 45 minutes prior to impact. V2 occupant2 added the force of the impact also pulled her under water for several seconds. 
  
  Lake City Marine arrived to tow the vessel. With the assistance of the crane on the barge, the pontoon was righted in the water. I observed damage to the walls of the pontoon boat. One of the seats was removed from the vessel. The pontoon boat appeared to a total loss. I photographed the scene. Lake City Marine towed the vessel to their lot. Dep. transported the pontoon boa
