Description:

Abstract:
The Global Reservoir and Dam Database, Version 1 (Revision 01) contains 6,862 records of reservoirs and their associated dams with a cumulative storage capacity of 6,197 cubic km. The dams were geospatially referenced and assigned to polygons depicting reservoir outlines at high spatial resolution. Dams have multiple attributes, such as name of the dam and impounded river, primary use, nearest city, height, area and volume of reservoir, and year of construction (or commissioning). While the main focus was to include all dams associated with reservoirs that have a storage capacity of more than 0.1 cubic kilometers, many smaller dams and reservoirs were added where data were available. The data were compiled by Lehner et al. (2011) and are distributed by the Global Water System Project (GWSP) and by the Columbia University Center for International Earth Science Information Network (CIESIN). For details please refer to the Technical Documentation which is provided with the data.
Purpose: To provide a geographically explicit and reliable database of dams for the scientific community.

Attribute:

Attribute Label: DEPTH_M
Attribute Definition:
Average depth of reservoir in meters; calculated as ratio between storage capacity ("Cap_mcm") and surface area ("Area_skm"; values that are somewhat higher than the dam height ("Dam_hgt_m") may still be reasonable, e.g. if the storage capacity refers to the maximum volume yet the reservoir polygon represents a low-fill status; values capped at 1,000 indicate exceedingly high values, which may be due to inconsistencies in the data
