Freshwater ecosystems are a subset of Earth's aquatic ecosystems that include the biological communities inhabiting freshwater waterbodies such as lakes, ponds, rivers, streams, springs, bogs, and wetlands. [1] They can be contrasted with marine ecosystems, which have a much higher salinity. Freshwater habitats can be classified by different ...
Connectivity between streams and lakes relates to the landscape drainage density, lake surface area and lake shape. [15] Other types of aquatic systems which fall within the study of limnology are estuaries. Estuaries are bodies of water classified by the interaction of a river and the ocean or sea. [13]
Lakes and ponds experience much of the same pollution as rivers and streams, but are polluted at a quicker rate due to slower moving waters, no water flow outlets, and amount of water. [16] Standing water circulates much less than moving waters, with the deeper water layers only moving during seasonal changes twice a year. [16]

Freshwater lakes contain about 87% of this fresh surface water, including 29% in the African Great Lakes, 22% in Lake Baikal in Russia, 21% in the North American Great Lakes, and 14% in other lakes. Swamps have most of the balance with only a small amount in rivers, most notably the Amazon River. The atmosphere contains 0.04% water. [15]
Artificial lake or artificial pond: see reservoir (impoundment). Barachois: A lagoon separated from the ocean by a sand bar. Canada Basin: Bay: An area of water bordered by land on three sides, similar to, but smaller than a gulf. Bayou: A slow-moving stream or a marshy lake. Southern US Beck (stream) or Beck (gill) A small stream (esp. with a ...
For natural pond conservation and development, one way to stimulate this is with general stream and river restoration. Many small rivers and streams feed into or from local ponds within the same watershed. When these rivers and streams flood and begin to meander, large numbers of natural ponds, including vernal pools and wetlands, develop. [40]
The brook trout is native to small streams, creeks, lakes, and spring ponds. Fish are probably the best-known inhabitants of lotic systems. The ability of a fish species to live in flowing waters depends upon the speed at which it can swim and the duration that its speed can be maintained.
