RedactedNarrative: On 08/30/2015 at about 17:20 hours I was on duty at Canyon Lake. I was in the Aid Station observing boats on the Lake. 
  I saw a small open motor boat going in a sharp circle with three small children on board. I saw two adults in the water and the boat appeared out of control. The back of the boat was taking on water and was sinking. The children were all wearing PFD''s. 
  I quickly got on one of our patrol boats with Deputies. We hurried to the scene of the sinking boat. At this time the boat was over turned and the rear was sunk with only the tip of the bow sticking out of the water. 
  The two adults helped us get the three children in the boat. The children appeared unhurt. We helped the two adults on board our boat. 
  
  Occupant1 appeared completely exhausted after we got her on our boat. She was lying down and could not get up. She was yelling for her children. I could smell the strong odor of an alcoholic beverage coming from Occupant1. She also had blood shot watery eyes and slurred speech. Subject2 also had blood shot watery eyes and slurred speech. 
  
  We got everyone back to our boat house and Deputy began medical treatment of Occupant1. Occupant1 had ingested some lake water. 
  
  The boat belonged to a friend of Subject2''s. The boat was a 1970 Meyers 12'' open motor boat. The boat was controlled by a hand throttle coming directly off the engine. 
  
  At the boat house I asked Subject2 if he was operating the boat. He told me no, he was not that it was Operator. I asked how much alcohol he had to drink and he refused to tell me. Subject2 was admitted that he was not operating the boat and that he would not be responsible for something he did not do. 
  
  I performed the Horizontal Gaze Nystagmus test on Subject2 and he would not keep his eyes focused on the pen so the test was inconclusive. I did see some nystagmus in his right eye, but as he would not focus on the pen I could not make a judgement as to whether he was showing clues of impairment on the test. I requested he submit to a breath test and he refused. 
  
  I later spoke to Occupant1 in the Aid Station. She submitted to a breath test and it showed her to have a blood alcohol level of 0.238%. Occupant1 said she had ¼ of a 5th of liquor. I asked her who was operating the boat and she said she did not know. I asked her why she went out on the boat with her children after drinking so much alcohol. She said Subject2 was with her and she did not know he was also drinking alcohol. I asked her what happened to causes the boat to sink. She said she did not know. Occupant1 was transported to the hospital by AMR ambulance. 
  
  I spoke with Subject2 further. I questioned him about how much alcohol he had to drink. He told me he had a prior DUI and he said he was about a 0.10% BAC. He said he was over the legal limit. He said he knew Occupant1 was also drinking alcohol. He agreed that it was irresponsible of him and Occupant1 to take the young children out in the boat after have consumed so much alcohol, but that Occupant1 was their mother so if she was OK with it, it was OK. 
  
  Sgtand I were able to get the sunk boat to the Palo Verde boat ramp. Occupant1''s husband was at the lake. He had not been drinking alcohol and he took custody of the children and the boat. 
  
  I interviewed occupant3 with his father present. He told me Subject2 was operating the boat and Operator asked to operate it. Subject2 let go and no one was holding the controls. The engine started to turn and Operator grabbed it tried to pull it strait, but the boat started going in a circle and sinking. 
  I interview Operator with his father present. He said no one was holding the steering …
