How long do lakes last?
The Life Cycle of Lakes All lakes, even the largest, slowly disappear as their basins fill with sediment and plant material. The natural aging of a lake happens very slowly, over the course of hundreds and even thousands of years. But with human influence, it can take only decades. A lake's plants and algae slowly die.
