A group of family and friends were boating on a pond.  The group deployed the anchor on the pond in about 60 feet of water.  As the operator attempted to secure the boat to the bottom it was clear that there wasn't enough scope on the anchor line in these conditions to hold the vessel.  He retrieved the anchor and tried again but it is unclear whether or not the anchor was securing the vessel.  The group decided to go swimming. One adult (not wearing a pfd) was swimming with a 4 year old (who was wearing a pfd) in about 60 feet of water.  He had consumed a beer and 2 nips during the day.  He became tired and called to the people left on the vessel to come get the child and get him a pfd.  The boat started drifting away from the swimmers because of strong winds.  Two males entered the water one to retrieve the child and the other to bring a pfd out to the adult.  Neither of these two adults wore a pfd.  The original adult and child in the water made it back to the boat.  One of the males who jumped in started struggling and but was helped back to the boat by the original adult in the water.  A woman on the boat was trying to start the engine but was unable to.  The other male was trying to get back to the boat but went under and was not seen again until his body was recovered the next day.  Improper anchoring and operator inexperience were the causes of this accident.  No charges will be taken out.
