RedactedNarrative: On 5 July, 2017, at approximately 16:00 hours, SALECS dispatch aired a call to any available Casper Game Wardens regarding a boat accident on Alcova Reservoir.  I responded and dispatch informed me that the accident had occurred on 1 July 2017 and that the reporting party (RP) was one of the boat owners involved in the accident and he had reported it to the Natrona County Sheriff's Deputy at Alcova Reservoir.  
  
  I contacted Deputy via phone, she informed me that the RP's boat had been struck while it was tied up in Natrona County slip (rental) number 6; she investigated the damage to the RP's boat and noted that it was minor, an approximate 4" square cracking of the get coat on the rear-starboard area of the vessel.  I contacted the RP via phone. 
   Subject had rented Natrona County boat slip number  from 30 June through 9 July.  Subject stated that his boat had been tied up in the slip when it was likely struck on the starboard side by a boat docking into rental slip number 7.  Subject stated that on 1 July, immediately after he had checked his boat into slip, an individual occupying slip number 7 approached him and said something approximating "Hey, sorry I hit your boat earlier."  Subject stated that he assumed the individual was joking and did not identify the damage to his boat until the 5th of July when he reported it to Deputy.  I asked Subject to estimate the amount of damage to his boat, he was unsure as to whether it was greater than $500; I instructed Subject to get an estimate of the damage at a repair shop to determine if a boat accident report was required.  
  
  On 6 July 2017, I contacted Natrona County Parks and identified the individual who had rented slip number 7 and contacted him via phone.  The individual denied any contact between their boat and the boat in slip number.  These slips are frequently used by people who have not rented the slip.  On 27 July 2017, I received a call from Subject at approximately 13:00 hours; he stated that he had gotten a damage repair estimate from Central Paint & Body, Inc., for $8512.35  At this point, I initiated a boat accident report and investigation.  Per the investigation, I identified a spiraling crack in the gel coat of approximately 6" in diameter on the rear starboard side of the boat, along with rub marks which had removed a 1" square section of pinstripe tape.  In approximately the middle starboard side of the boat, multiple rub marks ranged in size up to 1 square inch had worn through the gel coat and contacted the fiberglass.  On the starboard bow area of the bot I identified a 3" square blue paint transfer.  On the port side of the boat were three distinct areas where the boat had rubbed against the dock, potentially as a result of coming into contact with the boat in slip number.
