RedactedNarrative: SYNOPSIS
  I investigated and did a boat accident report for a possible Carbon Monoxide poisoning case. One individual onboard a houseboat exhibited symptoms of CO poisoning, there was no damage to the houseboat. Report was filed.
  
  INITIAL CONTACT
  At approximately 11:00 am on Saturday, August 31st, 2019 in Bullfrog, I (Ranger Lake Powell) overheard NPS Dispatch state that a medical call (possible CO poisoning case) was en route to the Bullfrog Clinic.  The party involved was self transporting by vessel to Bullfrog. I responded to the Bullfrog Clinic and made contact with the family. I arrived and a 7 year-old male was already getting treatment by Bullfrog Clinic Staff, including oxygen treatment.
  
  NARRATIVE AND INVESTIGATION
  Victim's grandpa described the details of what had occurred. He stated that Victim had been warming himself on the swim deck of the ski boat near the back of the houseboat (identified as the SUM-R-RAIN) for approximately 10 minutes near the generator vent. Grandpa stated they had the generator running on the houseboat for a couple of hours, which he stated they generally didn't do in the middle of the day. One of the other kids on board notified adults on board when they observed Victim "not acting right/strange". Victim's mother stated she went to the ski boat and observed Victim to be crying, not responding and lethargic.  She said they then carried him to the ski boat and headed to Bullfrog to get treatment for Victim. Grandpa also stated that Victim and the other kids on board wouldn't usually hang our near the swim deck. Mother further stated that Victim said his "brain feels weird" and that he said he "feels really weird".
  
  Mother said in her witness statement, "went check on Victim, he was laying on the swimstep of the ski boat, near the houseboat. Generator was on and he was near the exhaust. He was unresponsive. I went to pick him up, and he was limp and then said he felt really weird. He couldn't hold his weight and just wanted to sleep. We brought him into Bullfrog. He stayed awake and said he had a headache". Grandpa followed up with me later and stated that Victim "returned to his normal level of activity by the evening of the incident". Clinic staff administered oxygen to Victim for approximately an hour and stated his "CO levels were a 16.7% with 96.8 ppm" when he first arrived. "As CO levels increase and remain above 70 ppm, symptons become more noticeable and can include headache, fatigue, and nausea. At sustained CO concentrations above 150 to 200 ppm, disorientation, unconsciousness, and death are possible". "Levels of carbon monoxide exposure range from low to high, as described in the following list: Low level: 50 PPM and less, Mid level: Between 51 PPM and 100 PPM. High level: Greater than 101 PPM". Victim was in the mid level of CO exposure. They stated he felt much better after an hour, and was completely responsive. Both his headache and nausea were resolved. See attached witness statements, and Victim's medical records. 
  
  
  CONCLUSION
  Additional follow-up was conducted and information gathered. Based on my investigation, witness statements and medical records - the main factor in this incident was a possible lack of Carbon Monoxide poisoning awareness, and allowing individuals on the back of the houseboat while the generator was running.  The cause of this incident was likely Carbon Monoxide fumes from the generator, exiting the generator vent close to where Victim was laying.  There was slight delay in submitting this report, due to a delay in receiving required information for the report.
