A Seattle man fell from the bow of a moving boat into Lake Powell, and rescue workers are still searching for him, according to the National Park Service.

Luke Rogers, 19, was standing on the bow seat of a powerboat on Saturday while it was moving. When the person operating the boat slowed it down, Rogers was thrown into the water.

After hearing a thud, the person operating the boat and another passenger looked for Rogers and called for help on the marine band radio. The Glen Canyon National Recreational Area dispatch got the report at about 1:28 p.m.

Several agencies were still searching for Rogers on Monday.
