Dams, Lakes and Reservoirs Database for the World Water Development Report II

The dams and reservoirs database is a global databank of 633 large impoundments
from a series of world dam registers published by ICOLD and IWPDC (ICOLD,
1984;1988; IWPDC, 1994; 1989), with the following attributes:
- Dam name
- Year
- River Nam
- Nearest City
- Province
- Country
- Continent
- Dam Type
- Length
- Volume of dam body
- Reservoir Capacity
- Area
- Latitude and Longitude

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
1995). Lake volume was calculated as the product of estimated lake depth and
surface area.
