I went out for the first time today......

The water temperature was right at 65 degrees. The lake's a "heated" lake due to a power plant that uses the water to cool the plant, and "dumps" the water into the lake. It's not unhealthy, except for the fact they tell you to limit the amount of fish you eat out of it due to high levels of mercury! In July/August, the water temp's anywhere from 98 to 107.

Anyway, I'm trying to compare with other places. I'm in North Carolina, and 65 degrees feels pretty cold (don't worry, I'm still gettin' in), but I wondered what water temperatures others endure elsewhere. April - August????
