Do ponds eventually fill in?
If left alone, the pond or lake will eventually fill in completely, and become a swamp or wetland at best. Most existing farm ponds fall in the eutrophic category and need help quickly to slow the aging process.

How deep does a pond have to be to be a lake?
A pond is a body of water less than 0.5 acres ( 2023.428 square metres) in an area or less than 20 feet (6 meters) in depth. A lake is defined as a body of water bigger than 1 acre (4,000 m²), although size is not a reliable indicator of its water quantity.
How does a pond turn into a lake?
During the summer, if a waterbody is deep enough to stratify into three distinct layers, with one warm layer on top, one cold layer at the bottom and a layer of rapidly changing temperature in between (called a “thermocline”), then it is a “lake,” while a waterbody with one or two weakly defined layers is a “pond.”
What is the bottom of a lake called?
The material at the bottom of a lake, or lake bed, may be composed of a wide variety of inorganics, such as silt or sand, and organic material, such as decaying plant or animal matter.
Can you swim in a pond?
Along with water quality, it is important that the physical characteristics of a pond are appropriate for swimming. The depth of the pond can often determine if it is safe to swim. In addition, sunken trees and submerged rocks can be invisible from the surface of the water and can pose a danger to swimmers.
What is the bottom of a pond or lake called?
