Analysis

The float plane plt was on a VFR flt at night to nasworthy lake near San Angelo, TX. He continued into deteriorating wx conditions. Subsequently, while cruising below the clouds, the acft impacted terrain at an elev of about 2500' MSL. In a written statement, the plt stated that he was attempting to maintain 3500' MSL & encountered strong downdrafts. However, in earlier conversations with an FAA coordinator, he indicated he was trying to maintain a lower altitude (aprx 200' AGL). Rprtdly, impact occurred as the acft was flying at about 90 KTS.
