RedactedNarrative: On 9/1/19 at approximately 1607 hours, a thunderstorm and possible micro burst struck Roosevelt Lake. There were three boats in the Bumble Bee area North of Bermuda Flats. The three boats were beached and the subjects were eating lunch. The waters turned rough and the waves began pounding the boats. The boats began to fill with water and swamped. The one vessel capsized.
