Hot Water Swimming--Stay or Go?

Hot-that water was hot when I put my face in the water. After all that digging out my pond last year to have a place to swim, now the water temp is higher than that of most whirlpools. Do I stay or do I go? Do I even try this? I pushed on and the more shallow the water, the hotter it became. A thousand yards later I was walking out of the water on shaky legs. My heart was racing; pounding hard in my chest. I had to sit down on the bank and try to get my stuff back. I won't do that again. Can't say that was even a little fun. Sometimes discretion is, indeed, the better part of valor.
