A stream pool, in hydrology, is a stretch of a river or stream in which the water depth is above average and the water velocity is below average.[1]

Formation

Stream pool formation.

A stream pool may be bedded with sediment or armoured with gravel, and in some cases the pool formations may have been formed as basins in exposed bedrock formations. Plunge pools, or plunge basins, are stream pools formed by the action of waterfalls. Pools are often formed on the outside of a bend in a meandering river.[2]

Dynamics

The depth and lack of water velocity often leads to stratification in stream pools, especially in warmer regions. In warm arid regions of the Western United States, surface waters were found to be 3–9 °C higher than those at the bottom[3]

Habitat

This portion of a stream often provides a specialized

stagnant water, can be found in stream pools due to the low water velocity.[5]
