Lake Level Reconstruction

Pyramid Lake/Pyramid Island       Viau and Gajewski 2001 Holocene Lake Status Map

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 levels. A history of moisture balance and climate in the basin can then be derived.
