A Texas man drowned at Fort Supply Lake at approximately 1:30 p.m. Sunday afternoon.

Mario Sebastian-Mejia, 18, of Dalhart, Texas, was on the west side of the lake when he went under and never resurfaced, according to Woodward County Sheriff Kevin Mitchell. Sebastian-Melia was at the lake with his family.

“They weren’t real far out in the water, but for some reason he went under and didn’t come back up,” Mitchell said. “The lake is still up by four to six feet. You can’t see anything that’s under the water.”

Sebastian-Mejia had been wading outside of the swim beach area approximately 90 yards south of the boat ramp and about 50 feet east of the west shore line, according to the Oklahoma Highway Patrol incident report by Marine Enforcement Division Trooper George Hoyle.

In the report, Hoyle noted that witnesses said the man slipped off the jetty wall and went underwater. He was not wearing a personal floatation device, according to the report.

According to the report, side-scan sonar was used to locate the body which was recovered at approximately 4:50 p.m. in five feet of water. The victim was then transported to the Oklahoma Office of the Chief Medical Examiner in Oklahoma City.
