No lifeguards on duty. Always use caution in the gorge. Water may rise rapidly. Monitor your surroundings. Leave the gorge immediately if water begins to rise or you hear warning sirens. Watch for slick rocks and swift currents. Do not jump into water of unknown depths. Swimming or wading is not allowed in all areas from TVA’s powerhouse downstream all the way down to the main beach boat ramp including by the powerhouse, Twin Falls and Blue Hole due to hidden and deadly currents.
