Attempting to land at [a private airport] with 3500 [feet of] runway was unsuccessful resulting in running off the north end of runway by approximately twenty feet landing in a water pond completely submerging the airplane in water. Evasive action was near impossible as there were no less than three other aircraft flying overhead on a fly-by no more than 50 feet above me. Attempting to power had resulted in a midairup to go around would  collision due to the close proximity of the overhead aircraft. No air traffic control was provided for approach; landing; takeoff and fly-by of aircraft. It is a see and be seen approaches; departures and fly-bys. There were no injuries sustained and damage was confined to aircraft; to include aircraft completely submerged in water; right center section of wing bent by coming into contact with small 2 [inch] - 3 [inch] diameter tree at edge of water; left and right wing tips; left and right wheel pants and both cowling cheeks upon coming into contact with water. I had no physical impairments or illnesses prior to; during flight and subsequent landing. Not on any medication affecting performance or judgment. My decision to go into the water resulted in damage to my aircraft to avoid injuries to bystanders and aircraft flying overhead.
While attempting to land at a private airport; the pilot of an experimental aircraft was unable to stop on the usable runway. Fearing a conflict with overhead aircraft if a go-around was attempted; the pilot ran off the end of the runway and into a pond.
