Because the force of the flow / tide is no longer strong enough to carry it.
Generically it is called "sedimentation", in lake the sediments can be called "varves".
Generically they are called sediments
It is called a River Delta.
The bottom is called bathymetry.
The sediments on the lake bottom undergo lithification and become sedimentary rock. Further compaction, pressure, and heat turn it into metamorphic rock.

The storms create temporary streams. The streams carry sediments with them. Soon these sediments are settle down creating a graded bedding.

They form by sediments of rocks getting squeezed together at the bottom of a lake. Some of those rocks are Conglomerate, Limestone, and Sandstone.
Most of the fish preferred are ones such as catfish and carp from river and lake bottoms which are usually picking up the sediments from the bottom.
Settlement and compaction. As particles (sediments) are dumped, lets say, at the bottom of a lake, they will begin to settle and eventually harden into a sedimentary rock.
When a river flows into a lake or ocean, the sediments that the river carries settle to the bottom. Layers of sediment may covor the dead organism.
