The picture that shows the blue water was one of my favorite spots we visited on our vacation. The water is blue there after it comes out of the cave. It than flows into the main lake where I am swimming in the other photo. The water coming out of the cave there was below 60 deg in comparison with the rest of the lake water which was about 80 deg. The lake was great for swimming and boating. Chris and I rode a jetski and did some parasailing and Kerry, Chris and I rented a larger boat for fun. We all went swimming off the boat in one of the coves. I love the water. (can you tell)? :)
