Streams can't erode their channels endlessly. there is a lower limit to how deep can a stream erode. Base level is the lowest point to which a stream can erode its channels.

Close to the base level.
Lowering a stream's base level will cause the stream to do what?
The results of a lower base lever for rivers and streams is the sea level falls and the land rises. The base level is the level below which a stream cannot erode.

Seal level is the ultimate base level for rivers that discharge into the Oceans; thus sea level is the base level for the Mississippi River.
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.
The base level is the lowest point to which a stream can erode its channel. This can be the level of the body of water into which the stream flows, such as a lake or ocean, or an artificial structure like a dam. At base level, erosion stops and sediment deposition begins.
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.
The level of a body of water that a stream flows into is called the "base level." It represents the lowest point to which a stream can erode its channel. When a stream reaches its base level, it can no longer lower its bed through erosion, leading to sediment deposition instead. This base level can be influenced by factors such as sea level, dams, or geological uplift.
