RedactedNarrative: On 07/01/17 at 2102 hours I was dispatched to a report of a non injury boat crash at Bagley Flats, Saguaro Lake, Tonto National Forest.
  
  Complainant was contacted by telephone and advised an unknown "ski" type watercraft struck a PWC which was docked on his moored house boat. At this time Subject indicated the only damage he observed was a scuff mark on the PWC and it was too dark to check for more damage. An attempt to locate the ski watercraft at boat ramp 1 and 2 was conducted with negative results based on the limited information available at the time.
  
  On 07/02/17 I traveled out to Bagley Flats where I made contact with Subject. It was ultimately discovered there was damage to the aft port side of the floatation pontoon in the form of scraped metal. There was also a structural weld which was broken on the interior portion where the scrape marks were observed. Subject advised his Mathers throttle control electrical equipment, located in the same compartment as the noted damage, was not functioning properly.
  
  A witness indicated he hear a loud noise at which time he observed a blue/white ski watercraft strike Subject''s watercraft with the aft port side of the ski boat. Witness was not able to identify any of the occupants of the ski boat.
  
  No further action or investigative leads at this time.
