RedactedNarrative: On Friday, 7-22-2022 at approximately 1817 hours, MCSO was contacted via the emergency call box at the Palo Verde Recreation Area at Canyon Lake reference a boat that capsized.  An unknown person reported a red and white boat had capsized somewhere on Canyon Lake.  The complainant advised there were approximately 10 people on the rocks by the bank who had flagged them down and asked them to call for help.  They advised they did not believe anyone was injured. 
  
  At approximately 2000 hours, Dep. and I arrived on scene at Canyon Lake.  No one from the sunken vessel was able to be located on shore.  Dep. was able to locate the partially sunken vessel in Captain Nemo Bay (GPS Coordinates: 33.55754 / -111.42627).  He advised the bow of the boat was sticking up out of the water.  The Registration number was visible.  After a thorough search of the area, no one was located on the shore near the vessel.  Unknown people at the Palo Verde Recreation Area dock advised Dep. another boat had brought in the people from the sunken vessel.  It is unknown where those people went after they came to shore.   It was unknown what occurred to cause the boat to capsize.
  
  On Saturday, 7-23-2022, at approximately 1015 hours, during daylight hours, I was able to locate the partially sunken vessel.  I observed approximately five feet of the bow of the boat (colored red and white) was sticking up out of the water.  There were numerous white and gray colored seat cushions on the shore near the boat, which appeared as though they may have been used as flotation devices.  Due to the majority of the boat being underwater, I was unable to view any possible damage to the watercraft.  The boat appeared to be tied to a large boulder on the shore with a pink colored rope.  At this time, evidentiary photos were taken and entered into Evidence.com.
  
  I was able to use the boat registration information to find the owner.  I attempted to contact Owner a few times and left a voicemail for him to contact me.  At approximately 1200 hours, I contacted County Sheriff''s Office in Texas (the law enforcement agency with jurisdiction over Owner'' residential address) and asked them to go to Owner'' address and attempt to locate him or his next of kin and ask him to contact either myself or the Maricopa County Sheriff''s Office Lake Patrol Division.
  The U.S. Forest Service was advised of the partially sunken vessel due to environmental issues with gas and other contaminants which may be leaking into the water.
  
  Nothing Further.
