RedactedNarrative: Vessel 1 was a Green flat bottomed Old Town canoe being operated by 2 individuals.  Vessel 1 capsized and sank approximately 100 yards from shore.  Both were wearing Type 3 PFD.  Victim had hold of a dry box containing their phones and keys, but in the struggle to swim to shore, he lost contact with it.  They swam to shore and were assisted out of the water by fisherman on shore.  They were moved into a Provo City FIre and Rescue ambulance where their wet clothes were removed, and they were wrapped in mylar blankets, and heating pads and warm saline bags were placed in on their bodies to help bring their temperatures up.  Both were shivering uncontrollably.  Temperatures were taken, and one was at 88 degrees and the other at 92 degrees.  They were put into Tyvek suits to help trap further warmth.  More Hand and body warmers were used to bring their temperatures up.  After a while they both stopped shivering and their body temperatures returned to being close to normal.  Cognitive thinking, and coherency improved greatly.  I gave my phone to them to see if she could use it to locate her phone as it was still in the dry box with their other belongings on the lake.  She was able to track it on my phone, and I went out on the water to look for it in the Park Rescue boat.  The dry box was not, and still has not been located as of April 21, 2022.  
  
  The ambulance crew transported them home by ambulance as they had no keys to drive their vehicle, and did not have any phone numbers memorized of anyone that could come pick them up.  There was no other medical aid beyond warming them up.
