Vessel B was near the dam at the North end of the lake pulling 2 females on a ski tube.  There was one person in the boat which was the operator.  The operator observed another vessel approaching them at a fast rate.  The operator slowed the boat and eventually the boat came to a stop.  The operator had hoped there would be enough room for the other vessel to pass between them and the dam.  The other vessel ended up turning left between the vessel B and the tube striking the tube the girls were in causing injury to them.  Vessel A stated that he was pulling his son on water skis and noticed the other boat and tube some distance ahead of him near the dam.  He thought they were far enough away from the dam that he could go around them.  When he got closer he realized that he could not get around the other boat and turned the boat behind them striking the tube.  Operator indicated that his boat hydroplaned and that the other boat was not going as fast as he thought.  After the accident, the security boat patrol rendered at the accident scene and called for help.  Both the injured girls were loaded into the security boat and transported to the security dock when the police and EMS were waiting.  Victim 1 was transported along with Victim 2 to Shawnee Mission Medical Center.  Victim 1's injuries were a broken right arm and Victim 2's injuries were bumps and bruises.  Both girls were wearing PFD's.
