A reach in geography can mean several things. Most generally, a reach is any length of a stream between any two points. The points may be selected for any reason, such as gauging stations, river miles, natural features, and topography. They may be arbitrary or vague.[1][2]
A reach may also be an expanse, or widening, of a stream or river channel. This commonly occurs after the river or stream is dammed. A reach is similar to an arm.
The term "reach" can also refer to:
- An extended portion or stretch of land or water;
- a straight portion of a stream or river, as from one turn to another;
- a level stretch, as between locks in a canal;
- an arm of the sea extending up into the land.
