INITIAL NOTIFICATION: After checking on duty, I drove to the boat ramp to check on boaters due to the sudden approach of a micro-burst wind/rain storm. The wind was blowing primarily out of the south. I observed what appeared to be several boats struggling to negotiate the strong wind and waves. I boarded the park boat and headed in the direction of the struggling boats, which was straight off the main boat ramp in a northeast direction approximately three to four hundred yards. The next opportunity I had to visualize the boats, I observed one submerged but up-right and the other submerged and beginning to capsize approximately 100 yards apart. I had dispatch locate Ranger Wilson to respond, as well as Washington County Search and Rescue (SAR) Dive Team.
RESCUE: All occupants jumped in the water and were wearing life jackets. I began picking up the occupants of the two submerged vessels. I ensured that there were no injuries and that everyone was accounted for. I was told by the boat operators that everyone was accounted for and I then transported them to the dock. After dropping of the boat occupants at the dock, Ranger and I responded back out on the lake to check for any other vessels in distress. We found another boat (Vessel #1, this report) submerged and capsized against the north dam with the occupants on the dam. We were told everyone from that boat was accounted for and uninjured. They said they were fine with waiting on the dam. We arranged to have the access gate unlocked so they could start loading their belongings.
SALVAGE OF BOATS: I was then contacted by the SAR dive team and informed that they can no longer respond to non-life threatening emergencies, after hearing of no injuries and that everyone was accounted for. I then had a county deputy on scene cancel SAR due to no life-threatening emergencies and made contact with Roger's Performance Marine (RPM) who is the closest boat shop. Ranger Wilson and I attached marker buoys to the two capsized boats in the open water in case they eventually sank.
RPM was the closest and only private operation with the necessary equipment, or access to the necessary equipment to salvage the boats that I was currently aware of. Since RPM was able to respond immediately, I had them respond to assist, as it is imperative that the boats are removed as soon as possible due to the pollution/contamination of the water body. Once RPM arrived, he began towing the capsized boats to the dock. RPM also had a large tow truck respond, which was able to assist with rolling the boats right side up and loading them onto their trailers.
The owner and occupants of Vessel #1 were able to pull the capsized vessel along the dam to the east end of the dam where they were able to upright it themselves. I assisted them in pumping water out of the vessel while several of the occupants bailed. They finally removed a majority of the water and we were able to tow the vessel back to the dock with the patrol boat. 
INVESTIGATION: Vessel #1 was in the north end of the reservoir when the micro-burst wind storm arrived. As the storm was worsening, the operator turned the boat into the waves to avoid being blown into the dam. As the vessel was making forward progress through the waves, it began to take on more water over the bow than the bilge and other pump they were using could handle. The vessel became fully submerged and after all occupants had jumped in the water with life jackets, the vessel capsized. The owner of Vessel #1completed a brief witness statement about the incident.
Vessel #1 was transported by the owner to the boat storage area inside the park where it was secured for the night. After the other boats were loaded onto trailers, Ranger Wilson and I cleared the incident with dispatch and continued with the investigations. The owner of Vessel #1 took the vessel with him when he and his group left the next morning.
