THE PLT WAS DELIVERING SUPPLIES FROM A MOUNTAIN SITE TO A RIVER WORK SITE. HE STATED THAT ON HIS 10TH & LAST FLT, THE WIND CAUSED THE HELICOPTER & EXTERNAL LOAD COMBINATION TO SHIFT LATERALLY. AT THAT TIME, THE LOAD/LINE BECAME ENTANGLED IN A TREE. THE HELICOPTER BEGAN MOVING IN AN ARC & SUBSEQUENTLY CRASHED IN THE RIVER. THE PLT STATED THAT HE WAS UNABLE TO RELEASE THE LOAD; ALTHO, HE HAD PREVIOUSLY CHECKED THE ELECTRICAL & MANUAL RELEASE MECHANISMS & THEY OPERATED NORMALLY. HE ESTIMATED THAT THE WIND WAS FROM 050 DEG AT 5 GUSTING 7 KTS. THE ELEVATION OF THE CRASH SITE WAS ABOUT 3100 FT.
