*The maps on this blog, and the details, have been updated since it was first posted. Special thanks to Fan Xiao, the chief engineer of the Sichuan Geology and Mineral Bureau in Chengdu, for providing details on Minjiang dams. What follows is the most up to date publicly available information on hydropower projects in the region.
This is an update on maps I shared on this blog on Zungchu/Minjiang and Gyarong Ngulchu/Dadu rivers. Thanks to encouraging and informative feedback from Bruce Lee, Fan Xiao, Kevin Li, Stone Routes, and from Probe International researchers, the following maps and tables provide a unique and reliable information on dams on the eastern edges of the Tibetan Plateau.
For the sake of simplicity and accuracy a project's Status has only four possible values: Built, Under Construction, Planned/Proposed, and Cancelled. The term "Built" includes HPPs that have started generating power but are not complete, as well as those that have been operational but are currently non-functional. "Under Construction" indicates that work is proceeding on the ground and does not necessary entail that the river has been blocked or diverted. "Planned/Proposed" includes those HPPs that are those projects which the design, environmental issues, financing etc. are being developed as well as those that have been discussed but have never made it to the drawing board in any serious way. "Cancelled" includes only those projects for which there is widespread agreement that the government has decided that the proposed projects will not go ahead. This does not mean that a similar project may not be in the works to get around of the cancellation of the original project.
Capacity is given in MegaWatts. This should be understood to be the planned maximum rated power generation capacity of the generators of a HPP when it is completed. While every effort has been made to assure their accuracy, these figures are often given somewhat different values in different sources. Power generation capacity of hydropower generators is developing quickly so they may change.
Height is given in meters and indicates the total height of the dam associated with the HPP.
United Nations Framework Convention on Climate Change Clean Development Mechanism (UNFCCC CDM) assisted projects have been included on the tributaries map for three reasons. One is simply that reliable information is available for them. A second reason is that they provide examples of the thousands of small HPPs built throughout China which may (or may not) have negative consequences to the environment or local residents. A third reason they are shown is that they are examples of where Carbon Trading funds are going, which means that the general public overseas are subsidizing these projects since the Carbon Credits bought are tax deductible in developed nations. The CDM reports are available on the internet and at the UNFCCC site. More information regards UNFCCC at Wikipedia.

Sources of data presented here: websites of Probe International, UNFCCC, China Guodian Corp., and a number of other web based resources. Various Chinese and non-Chinese maps of the area have been used for geographical information. The maps are only approximately to scale. The positions of the hydropower projects are approximate. A detailed professional map should be used for more accurate geographic information.
