A lake is a sizeable body of (usually) fresh water that can be either natural or man made. Natural lakes tend to be made when rivers flow into basins in the ground, filling them up to make a large body of water. Man made lakes can occur due to digging – for example, quarry lakes form when humans dig quarries deep into the ground.
Lakes can be home to many different species of fish, mammals and plant life. They can be used for boating, snorkelling, diving and other water sports. Whether they are of the natural or the man made variety, lakes are typically places of great biodiversity and this makes them very important spots to take care of.
It is important to note that salt water lakes exist as well as fresh water ones. Salt water lakes are sometimes caused ‘brackish’ lakes and they represent totally different ecosystems. These lakes should also be taken great care of.
