I swam in Jenny Lake a few years ago; it's near Jackson Lake and probably around the same temperature. I don't know what the exact water temperature is, but I'd qualify it as: friggin' cold. I do believe it's above 55F though. String Lake, which is just north of Jenny Lake, is supposedly warmer because it's not as deep.
