👉 Estuary is a type of river or water body located between two bodies of water, typically lakes and rivers. It is characterized by its narrow channels, often with a shallow depth, which allow for the passage of boats and other vehicles. Estuaries are important habitats for aquatic species such as fish, birds, and insects, as well as important breeding and feeding grounds for riverine mammals like salmon and otters. They also play a significant role in regulating water levels and influencing climate patterns.
