Gary Miller, 43, was arrested and booked with third-offense DWI, reckless operation of a vessel and operating a watercraft while under a driver's license suspension, the agency said.
According to witnesses, on May 6 at about 7:40 p.m. Miller was traveling downstream at a high rate of speed on the Amite River near French Settlement when he collided with an LDWF patrol vessel.
Miller required medical treatment and was released later that same night. The LDWF agent, Sgt. Randy Lanoux, suffered no injuries.
Miller's personal watercraft was badly damaged, while the patrol boat suffered minor damage.
On May 11, after LDWF agents received the results of Miller's blood test that allegedly showed him over the legal alcohol limit, a warrant was obtained for his arrest.
Third-offense DWI brings up to a $2,000 and one to five years in jail. Reckless operation of a vessel carries up to a $200 fine and up to 90 days in jail. Operating a watercraft while under suspension brings an additional one year suspension of his driving privileges.
