Lakelets are small, tranquil bodies of water that can be found all over the world. They are also known as pools, ponds, tarns, meres, lagoons, or basins. These synonyms can be used to describe lakes that are fed by streams or rivers, or created by natural or artificial means. A pool is typically a small, round, and shallow body of water, while a pond is larger and deeper. Tarns are found in mountainous regions and often have crystal-clear water. Meres are large shallow bodies of water found in low-lying areas. Lagoons are coastal bodies of water separated from the ocean by a barrier reef or island. Basins are artificially created bodies of water for irrigation or recreation purposes.
