The water level in lakes fluctuates with changes in moisture balance (precipitation minus evaporation)
within the lake basin. In closed basin lakes, particularly in arid regions, lake level fluctuations can be dramatic,
resulting in fossil shoreline deposits and other features indicative of past lake level. A history of
moisture balance and climate in the basin can then be derived.
