On Sunday, August 1st at approximately 6:00 pm, was pulling his cousin and her boyfriend on a tube behind his Personal Watercraft.  They were heading east bound on Big Cypress Bayou/Caddo Lake towards the Caddo Lake State Park No Wake Zone at approximately 18mph.  operator noticed a unidentified green flat bottom boat heading west bound towards him so he slowed down and veered towards the south side of the river.  As the boat passed him he turned around to head west bound on the river.  As he turned around and gave the Watercraft some gas the tube swung around and hit a wake causing a catipult affect sending tubers into the bank on the north side of the river.  At that time tuber wrapped other tuber up in his arms before he collided with a down tree on the bank.  At that time operator rushed to their aid along with two witnesses.  They asked tuber1 what he wanted them to do and responded to take him to the bank that him and tuber2 would drive to the hospital.  I was then contacted by one of the witnesses.  Texas Game Warden  was advised that the victims and the operator of the vessel was headed to Good Shephard Medical Center-Marshall Texas.  I met with the parties involved and started gathering statements.  tuber1 was admitted into the hospital and is pending release. 
Investigator with TPWD completed the Report.
