RedactedNarrative: Wco received a call from a reporting party (rp) at 6:22 am on 10/09/2021 concerned about a pickup and trailer parked at dry lake 2 boat ramp in clark co, sd for 2 consecutive days in the same spot.  Wco arrived on scene to investigate.  Wco and search & rescue performed a search on dry lake 2 via patrol and rescue vessels.  Search and rescue found v1 capsized near the north shoreline on dry lake 2.  Search and rescue located o1 of the boat deceased in the water nearby the capsized v1.  Wco responded to the location.  O1 was face down in the water deceased in approximately one foot of water on the shoreline wearing a personal floatation device.
  
  Search and rescue overturned/up righted v1 and pulled further into shore.  Wco conducted a search of the boat and found no damage to the boat besides what was caused by the capsized boat drifting into the muddy lake bottom to fishing equipment and plastic single counsel windshield.  Wco observed the v1 throttles to be in the upright neutral position and the key in the on position.  Search and rescue mentioned to wco that the bilge pump was in the one position after the boat was up righted.  Wco noticed that the top transom water release holes were plugged with boat plugs, and the plug in the boat was also in.
  
  Wco observed the body of o1 and personal floatation device.  The personal floatation device was buckled and o1 was wearing the flotation device with arms through the arm holes.  The personal floatation device was buckled with the second buckle into the third buckle on the personal floatation device.  The personal floatation device at that time was on the upper portion of the torso above the stomach area and pushed up toward the head of o1.
  
  Wco examined the v1 and found that the bilge pump fuse was blown, and an electrical light checker was in the boat wrapped around the throttle arm possibly showing signs of electrical issues in the boat.  Wco examined v1 to find no signs of v1 hitting any objects in the water.  Wco tested the starting capacity of the mercury outboard to see if there was a possible motor issue.  The outboard would not start, but this could be caused due to capsized boat, motor, and batteries for a period of time.
  
  Through investigation of the garmin marine graphs that were affixed to the v1, it appears to wco that the incident more than likely happened on wednesday, october 6th, 2021 at approximately 1:35 pm.  This was the last transmission of the garmin marine graph 345 feet from the capsized v1.
