I surely wouldn't do S Lake. There isn't a lot to like in S Lake IMO. Between Stateline and Incline on the E Shore would be the exception (Round Hill, Cave Rock, Glenbrook etc). The water on the E Shore and Incline feels way warmer to me because the prevailing winds come from the opposite side of the lake and blow the warmer surface water E. The water on the W shore is way colder. Maybe up to 10 degrees.The why is pure speculation on my part, but I'm pretty good at guessing water temperature. wj
