Crystal Lake, Decatur, AR?

[BillP]

Must be at least 35 years or so ago now, I remember spending a day snorkeling in Crystal Lake outside of Decatur, Arkansas. I had so much fun, the experience was one of the reasons I went on to scuba. I don't remember the lake being very big or very deep, but I do remember it being crystal clear (at least compared to what I was used to in Texas) and full of fish. Any of you ever dive it?

TIA,

Bill
