RedactedNarrative: At approximately 1330 hours, on August 9, 2020, I (Deputy) was notified of a jet ski collision involving two jet skis on Lake Tahoe, approximately 850 yards off Round Hill Pines Beach. At approximately 1400 hours, I arrived on scene at Round Hill Pines Resort and learned the following:
  At approximately 1310 hours, Operator 1 and his son, Occupant 1, rented a jet ski from Round Hill Pines Resort. Operator 1 was the operator and Occupant 1 was the passenger. 
  At approximately 1310 hours, Operator 2 and his sister, Occupant 2, rented a separate jet ski from Round Hill Pines Resort. Operator 2 was the operator and Occupant 2 was the passenger. 
  At approximately 1330 hours, Operator 2 and Occupant 2 were sitting on their jet ski approximately 850 yards outside Round Hill Pines Beach having a conversation about the water colors in Lake Tahoe. Operator 2's jetski had not been mobile on the water for approximately 1 - 2 minutes (I spoke to both Operator 2 and Occupant 2 independently and their stories both matched). While sitting on their jetski, speaking about the water, they both heard a noise coming from the right side of their jet ski. The noise was consistent with a jet ski moving on the water at a fairly high speed. Due to the noise, Operator 2 and Occupant 2 both looked to their right and observed a jet ski occupied by Operator 1 and Occupant 1 approximately twelve feet away moving directed towards them. Neither Operator 2 nor Occupant 2 had time to react to the incoming jet ski. 
  Operator 1's and Occupant 1's jet ski made contact with the right rear portion of Operator 2's jet ski, damaging multiple portions of Operator 2's jet ski (Operator 1's jet ski did not sustain any damage). Operator 1's jet ski also made contact with the right rear calf area of Operator 2 while she was sitting on the jet ski. 
  Operator 1 and Occupant 1 dismounted their jet ski and went into the water. Operator 2 and Occupant 2 remained on their jet ski and made it to shore so Occupant 2 could receive medical attention. 
  Operator 1 and Occupant 1 were able to get back on their jet ski and operate it back to shore without any further issues. Operator 1 and Occupant 1 were in the water for approximately 1 minute.
  Operator 1 later told me he was "fucking around" on the jet ski and neither he nor Occupant 1 noticed Operator 2's jet ski was not moving until they were very close to hitting it. Operator 1 said he was probably going approximately 35 miles an hour in the water prior to impact. Operator 1 did not know if he and Occupant 1 jumped off their jet ski prior to impact or if they were knocked off due to the impact. Operator 1 said "everything happened so fast". 
  I later made contact with Occupant 2 and learned she was transported to Carson Tahoe Hospital, by Operator 2, for further medical evaluation. Medical personnel were not originally required on scene or at the beach following the collision.
  While on scene, I took twenty six digital photographs of both damaged vessels. I was not able to take photographs of Occupant 2's injured leg due to her not being on scene.
