Lakes Lakes can range in size from small to large. They can be very deep or relatively shallow. Lakes that have depths of less than six or seven feet and plant life on the bottom, are often called ponds . There are no rooted plants at the bottom of lakes, because the water is too deep for sunlight to reach.
Lakes get their water from precipitation, from rivers and streams and from underground water.
Here Today, Gone Tomorrow Lakes are not permanent. Over time all lakes will shrink and disappear. Some will dry out, others will fill up with sediment. This doesn't happen overnight. The Earth is constantly shifting and moving.
