On February 25, 2012, at approximately 7:25 p.m. operator was operating TX vessel 2065 EZ on the Red River in Caddo parish.  Operator was locking northbound through Lock and Dam #5.  The vessel was tied up to the side of the lock during the locking process.  The water in the lock was rising and the port, bow of Operator's vessel got stuck in a recess on the side of the lock wall.  Operator did not notice the bow of his vessel was stuck in the recess.  The water continued to rise in the lock, and the vessel was pinned in the recess causing water to come in the vessel until it capsized.  Operator and his two passengers were able to swim to a ladder on the side of the lock wall and get out of the water.  All three subjects were wearing type 3 PFD's and the lockmaster was able to throw the subjects type 4 life rings during the incident.  The next day workers of Lock and Dam #5 were able to remove the vessel, and Operator took the vessel home.  No alcohol or drug use are suspected in this incident. The contributing factor in this incident was that Operator was not paying attention to the position of his vessel during the locking process and allowed the bow of his vessel to become pinned in a recess on the lock wall which caused it to take on water and capsize.
