Worldwide, there are

Tanganyikabeing the most famous.
Most other, short-lived lakes have a life span of less than 100,000 years
before they are eventually filled up with sediments. It is believed that in the
case of Lake Ohrid this process was delayed by its great depth and small sediment
input from its filtered spring inflows. Moreover the Ohrid-Korca graben to the
south of the lake is still tectonically active and might compensate
sedimentation by subduction. In contrast to Lake Ohrid,Lake Prespais likely to have turned dry several
times in its history, as a result of itskarsticunderground.In 2008, Macedonian media reported
that international experts will be researching the lake in order to determine
its age.
