C2 and C3 DESCRIPTION:
Documented lake volumes
were identified for 87 out of the total natural 6 392 georeferenced
lakes with known area (ESRI 1995; Lerman et al. 1995)
as developed in
Green et al. (2004). The small number of known lake volumes actually corresponds
to approximately 90% of the total volume of global fresh water lakes since the
largest lakes (Baikal, Tanganyika, North American Great Lakes, Victoria) are
well documented. For the remaining lakes lacking documented volume information,
average lake depth was estimated as a function of lake area class (ESRI 1995)
depending on glacial or tectonic origin (Meybeck
(C3) Lake_volume.asc = total water storage in lakes (km3 per grid cell). Primary source: Green et al. (2004).
