Funny you mentioned that, the picture shows what I think was the true color, I too think she is beautiful but I'm pretty bias. I don't know what would make her that color but believe it would be the characteristics of the water and/or the location of the pond. It sets low in what use to be a deep drainage ditch and is tile fed from ag land. The south side bank is probably 25 feet above the surface of the water level which leaves it shaded most of the year. Maybe it's a combination.
