RedactedNarrative: Operator approached the bank/sandbar near the intersection of Grand Bayou and Cross Bayou. Operator docked the boat and left the motor slightly engaged in forward. Operator did this in order to keep the vessel secured to the bank while he moored the vessel to shore, the current in this stretch of waterway is particularly strong. Meanwhile, Subject exited the vessel on the upstream/port side of the vessel in order to test the water for swimming. Subject exited the vessel voluntarily without a PFD. Upon making a few steps into the water, the water depth drastically changed from approximately 2 feet to approximately 10 feet. Subject was swept away by the current and was pulled towards the stern of the vessel, where she was struck several times by the propeller. Subject slipping into the deep water happened simultaneously as Operator was finishing up mooring the vessel. Upon mooring the vessel Operator turned around and noticed that Subject was missing. Operator then proceeded to the stern portion of the vessel where he saw Subject's hand grabbing for the steering rod located on the motor. Operator immediately turned off the motor and pulled her to safety. He then wrapped her in a towel to help prevent blood loss and called 911. Alcohol/drugs are not believed to be contributing factors.
