Do the INPE calculations include all large dams?
A large dam is defined by the International Commission on Large Dams (ICOLD)-the dam industry’s primary business association-as one that is over 15 meters tall. The ICOLD database used by the INPE researchers counts some 33,071 registered large dams. The actual number of large dams is likely to be closer to 50,000, mainly due to the large number of unregistered medium-sized (15-30m) dams in China.
