The lake is attractive, and the many turtles make it even more so. Most of the rock tops are occupied by the turtles. I'm guessing that they help keep the mosquito population down by eating the larvae in the lake before they hatch into adult mosquitoes. Here is a closer look at the turtles on a rock.
One of the most attractive features of the lake is the small waterfall that seems to fill it or recirculate the water from the other side of the bridge.
Do you have lakes, creeks, rivers, or oceans near you?
