KNOXVILLE, Tenn. (WATE) — A Morristown man died Saturday after falling into Cherokee Lake near the Kidwell’s Ridge Access Area.

Jeremy Gene Keen, 47, of Morristown, and his 14-year-old son were trolling in an aluminum Jon boat shortly before 8 a.m. when Keen fell into the water, according to the Tennessee Wildlife Resources Agency. While the boat continued to make circles, Keen’s son went into the water and was able to hang onto him.

Authorities said a fisherman nearby was able to pull Keen and his son from the water, but Keen did not survive. TWRA wildlife officers were able to stop the boat once they arrived on the scene.

Keen’s son was taken to Morristown-Hamblen Healthcare System and treated exposure to the cold water, according to TWRA.

“TWRA offers prayers and condolences for Mr. Keen’s son and their family,” the agency said in a release.

Neither Keen nor his son was wearing a life jacket, and the water temperature in Cherokee Lake was about 36 degrees, according to TWRA.

Wildlife officers “encourage boaters, anglers or anyone near the water to wear a personal flotation device” as even with a personal floating device, “someone falling into cold water may lose their ability to keep their head above the water.”
