Another word for a small river or stream is “brook.” Creek and rivulet also have a similar meaning. Most of the creeks, brooks and rivulets are found at the source of large rivers and in mountainous terrain. The waters of a brook or a rivulet appear clear and pollutant free.
A creek, a brook or a rivulet is smaller than a river and is likely to dry up during hot summers. These small bodies of water are generally shallow, and their water flows rapidly into a large river and are tributaries of the river. Brooks and creeks sometimes flow into large lakes.
