A stream pool, in hydrology, is a stretch of a river or creek in which the water depth is above average and the stream velocity is quite low.[1] Such pools can be important for juvenile fish habitat, especially where many stream reaches attain high summer temperatures and very low flow dry season characteristics. A stream pool may be bedded in sediment or armoured with gravels; in some cases the pool formations may have been formed as basins in bedrock materials. This portion of a stream often provides specialized aquatic habitat for organisms that have difficulty feeding or navigating in swifter reaches of the stream.
