any relatively large body of slowly moving or standing water that occupies an inland basin of appreciable size.
Pond
small area of still, fresh water. It is different from a river or a stream because it does not have moving water and it differs from a lake because it has a small area and is no more than around 1.8m deep.
River
continuously moving bodies of water that carry water from the source or headwater to the mouth at a lake or ocean.
Stream
are smaller bodies of water that flow through a channel or bed from one area to another.
Wetlands - areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season.
Estuaries - biomes that occur where a river, a source of freshwater, meets the ocean. Therefore, both freshwater and saltwater are found in the same vicinity; mixing results in a diluted (brackish) salt water.
Marsh
is a wetland that is dominated by herbaceous plants rather than by woody plants.
