RedactedNarrative: On 07/07/18 at1353 hours, Deputy and I were working uniform patrol on Bartlett Lake near Bartlett Flats on board Maricopa County Sheriff''s Office watercraft LP-81. A male subject, who was operating a yellow personal watercraft, pulled up to our watercraft and advised us that his daughter''s watercraft (Vessel #1) started to sink as she was operating it.  The subject asked us to follow him to where her daughter was which was along the shoreline of Tempe Beach.
  
      Upon our arrival at Tempe beach, we observed a red Bombardier RXT 215 personal watercraft (PWC) beached along the shoreline. The aft end of the PWC was submerged in the water. After beaching our watercraft, the subject who made contact with us earlier and who’s the owner of the PWC, a male subject removed the seat cover and showed us the inside of the engine compartment. The engine compartment was completely full of water and the engine was completely under water. 
  
      I made contact with the operator, a female subject. I asked Operator what happen. Operator advised me that while she was traveling south on the lake, the PWC started to slow down for unknown reasons. Operator said that when she let off the throttle, the PWC started to sink causing her to fall into the lake. Operator advised me that her son who was the passenger, remained on Vessel #1 while it sank. 
  
      Subject advised me that there was approximately $3500 in damages due to the engine would probably need to be replaced. 
  
      Both mine and Deputy MCSO body worn cameras were activated during the contact.
  
      There is nothing further at this time.
