RedactedNarrative: On July 02, 2016 Arizona Game and Fish Department (AGFD) Officers #1, #2 and #3 patrolled the Colorado River near Devil's Elbow on the Havasu National Wildlife Refuge by boat.  At approximately 4:45 PM Officer#1 and Officer#3 witnessed a boat later identified as a 2009, 26 foot Hawaiian boat with registration CFxxxxxx that appeared to have sunk.  Officer#1 witnessed a white boat with only the bow of the boat appearing from the water and an orange colored Bimini top protruding above the water line (see insert 1).  Officer#2 operated the patrol watercraft and maneuvered the patrol boat toward the sunken boat.  Officer#1 contacted the sunken boat and asked if anyone had any injuries.  All passengers stated that no injuries were present.  All passengers of the sunken boat except for a male subject later identified as Owner#1, boarded onto a boat which was operated by a good samaritan.  Officer#3 asked who the sunken boat belonged to and all passengers pointed to Owner#1.  Officer#1 interviewed Owner#1 who looked to be impaired by alcohol and asked Owner#1 who was operating the boat and Owner#1 stated his daughter was operating. Owner#1 stated the boat was operating perfectly all day and he had no idea how the boat sank.  Owner#1 stated once the boat took on water, it sank within a few minutes.  
  
  Officer#3 boarded the boat of the good samaritan and interviewed the passengers to see who was operating the boat.  All passengers stated to Officer#3 that a subject identified as Operator#1 was the operator of the boat at the time of the sinking.  
  Officer#3 escorted Operator#1 onto the patrol boat to conduct an alcohol impairment investigation.  Officer#1 asked Operator#1 how much alcohol he consumed for the day and Operator#1 stated he drank one beer several hours prior to the boat sinking.  Officer#1 and Officer#3 conducted Horizontal Gaze Nystagmus testing on Operator#1.  Officer#1 concluded that Operator#1 was not impaired at the time of operating the sunken boat.
  
  At approximately 5:55 PM, TowBoatUS arrived on scene and spoke to Owner#1 about the process to get his boat out of the water and back to land.  TowBoatUS stated that they would take care of the boat and agreed to contact Owner#1 once the boat was out of the water.  Relative#1 signed documentation with TowBoatUS that stated she agreed to terms and conditions in regards to TowBoatUS retrieving the sunken boat.  At approximately 6:05 PM, Owner#1 waved down his friend's boat and transferred all equipment and passengers into his friend's two boats.  Officer#1 provided Owner#1 and his wife the Department Report number for insurance purposes and ended the contact.  The cause of the boat sinking is unknown and the estimated damage value is $65,000 as stated by Owner#1.  This incident occurred in Mohave County within the jurisdiction of the Lake Havasu Justice Court.
  
  Officer#2 spoke to a repair shop about the reason for the boat sinking and the boat shop believed it was a hull failure.
