The elevation down to which a river has the ability to erode its bed everywhere along its course.
The ultimate base level of a steam is the lowest part of a stream or river. This is where the running water goes on land.

The ultimate base level of a stream is sea level. A base level is the lowest point to which a stream can erode its channel.
Ultimate base level
The base level of a river or stream is the lowest point to which it can flow, often referred to as the 'mouth' of the river. For large rivers, sea level is usually the base level, but a large river or lake is likewise the base level for tributary streams. All rivers and streams erode toward sea level, which is also known as the "ultimate base level." If a river is dammed, a new base level (the level of the reservoir) replaces the ultimate base level. As a result, the stream's base level is raised. Consequently, this reduces the stream's velocity, leads to deposition, and a reduction of the gradient upstream from the reservoir. A rather rare exception can be seen in the Jordan River, for which the base level is the Dead Sea, 417 m below modern sea level.

Lowering a stream's base level will cause the stream to do what?

base level-The lowest level to which a stream can flow. :)
The level of the lake
If you lower a stream base level it will cause a down cut. In some cases this is a good thing.
The lowest base level a stream may flow into is sea level in which it flows into the ocean.
The base level
· The stream will erode down through its bed to achieve the base level of erosion throughout its course. If this base level is low, then the stream will rapidly cut through underlying strata and have a steep gradient, and if the base level is relatively high, then the stream will form a flood plain and meander. http://en.wikipedia.org/wiki/Stream
