The NTSB's narrative final · quoted from the NTSB record

The pilot stated while conducting a wildlife survey the helicopter contacted and severed a powerline which resulted in the separation of the main rotor system at the rotor mast. The fuselage and tail boom came to rest inverted and submerged in a river. The pilot stated there were no issues with the helicopter that would have precluded normal operations.
