RedactedNarrative: On Tuesday June 28 2022, operator was operating a 21'' 2003 Triton bass boat (Vessel A) on Great Falls Reservoir traveling upstream on the Rocky River in Van Buren County.  While traveling upstream Operator1 saw an older model white ski boat (Vessel B) traveling downstream in the middle of the river channel on the Rocky River.  Operator1 slowed his speed as his boat approached the ski boat. The white ski boat was to the right of his boat so he yielded to his left to go past the ski boat.  When the boats were about 75 feet apart the ski boat turned to its right and into Operator1s path.  Operator1 turned his boat to the left to avoid hitting the ski boat.  As Operator1 was correcting his path, his boat made impact with an unknown object.  The impact caused Operator1 to impact his dash and cracked it loose from the boat. The impact caused the boat to start taking on water.  Operator1 tried to use his bilge pumps to pump the water out but the bilge pumps was not working after the impact. The front part of the boat was completely under water by the time it was able to be towed out.  The ski boat continued downstream and did not stop to assist.  Operator1 was not able to get the TN Numbers from the ski boat.
