This is the lake I used to go swimming in with my family as a kid. We don't go often, but I remember the ooey gooey mud and the dark brown water that might hide toe nibbling fish or any number of other mysteries.
The kids and I went there with Grandma and Grandpa Elliott the day we headed home to Colorado. It's a good thing we didn't have more than an hour or so to swim because the kids treated Grandpa like their own personal pool toy. At one point he was exploding up out of the water like a sea monster with four kids clinging to his neck and back. Shane didn't seem to understand that Grandpa wasn't going to let him drown so he had his arms in a death grip choke hold around Grandpa's neck. I started to actually fear for Grandpa's safety! The kids got incredibly dirty and then showered there before we left. It's definitely something we should do again next year sometime when Daniel is with us.
