Reach 

a deeper section of a river channel located between river bays. A reach usually forms at high water where the current of the river increases and severely erodes the river bed; for example, it can be formed where a river channel winds or where a river valley narrows. A reach is also a large deep section of a river that permits navigation without necessitating dredging up the river. Fish winter in deep reaches.
