Deep lakes

There are times when you can tell how deep a lake is just by looking at it. The surface could be super calm, but there’s a lot that the color of the water could say. When you can’t see below a certain point and it’s dark, it’s an indicator the well drops farther than you realize, he said. Lakes that are clear enough to let you see rocks or plants beneath the surface typically aren’t as deep, or at least not there. The light has so much to do with the way the depth appears. In more shallow water, light can touch the sea floor and bounce. Deep water doesn’t send that light back the same way. Depigmentation is common, frequently the color diffuses to become darker, or more uniform, and there are less characteristic features. You don’t always have to see the bottom to know it’s a long way down. The abrupt depth change can be felt in the way the edge of the water falls off. It’s easier to see how water behaves near the shore when you’re up above. A sudden change from lighter to darker water close to land generally indicates that the lakebed drops away steeply here. If the color is very pale far from shore, it may say that the slope is gentler. You can also see the way the water plays with objects. It's just that the impression is often the opposite, if a big rock rests near a dropoff and its foundation dives precipitously into black, the bottom must be far, far down there.
