Some lakes get filled up by the sediments brought down by the rivers and turn into plains in the course of time. Such plains are called lacustrine plains( or lake plains). The water may have disappeared by natural drainage, evaporation or other geophysical processes.

The soil of the plain left behind may constitute fertile and productive farm land, due to the previous accumulation of lacustrine sediment
