Stream pool

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 quite below average.

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.

Habitat

This portion of a stream often provides a specialized aquatic ecosystem habitat for organisms that have difficulty feeding or navigating in swifter reaches of the stream, or in seasonally warmer water. Such pools can be important for juvenile fish habitat, especially where many streams reach high summer temperatures and very low-flow dry season characteristics.

Steve Martin

HIDDEN ERROR: Usage of "signature" is not recognized

Stephen Glenn "Steve" Martin (born August 14, 1945) is an American comedian, actor, writer, producer, and musician.

Martin came to public notice in the 1960s as a writer for the Smothers Brothers Comedy Hour, and later as a frequent guest on The Tonight Show. In the 1970s, Martin performed his offbeat, absurdist comedy routines before packed houses on national tours. Since the 1980s, having branched away from stand-up comedy, Martin has become a successful actor, as well as an author, playwright, pianist and banjo player, eventually earning him an Emmy, Grammy and American Comedy awards, among other honors.

In 2004, Comedy Central ranked Martin at sixth place in a list of the 100 greatest stand-up comics. He was awarded an Honorary Academy Award at the Academy's 5th Annual Governors Awards in 2013.

While he has played banjo since an early age, and included music in his comedy routines from the beginning of his professional career, he has increasingly dedicated his career to music since the 2000s, acting less and spending much of his professional life playing banjo, recording, and touring with various bluegrass acts, including Earl Scruggs, with whom he won a Grammy for Best Country Instrumental Performance in 2002. He released his first solo music album, The Crow: New Songs for the 5-String Banjo, in 2009, for which he won the Grammy Award for Best Bluegrass Album.
