Has anyone ventured a swim in Jackson Lake, Jackson, WY? I have been able to substantiate swimming is allowed.

  • In my experience in California and Colorado, big lakes at similar elevations are unswimmably cold in June, with water temps under 50F. You would have better odds of water over 55F if you were going in August or September. According to Wikipedia, "The water of the lake averages below 60°F (16°C), even during the summer."
