Lakes caused by depositional agents are:
a. Lakes caused by landslides: These are formed when landslides block river valleys thus forming dam e.g. Lake Gormire in Yorkshire.
b. Lakes formed by glacial deposition such as moraine-dammed lakes e.g. Lake Plateau of Meck Lesbury in Germany.
c. Lakes formed as a result of river deposits, which occur when flooding fill some channels e.g. Flood plains of River Mississippi in USA.
d. Lakes formed by marine deposits: This occurs mostly along the coast when waves which build up spits and bars across bays form lagoons e.g. Florida Lagoon.
e. Lakes formed by alluvial deposits from rivers
f. Lakes formed by deposition by mass movement.
