Excerpts;

Water started flowing over an emergency spillway at the nation’s tallest dam, on Lake Oroville, for the first time Saturday after erosion damaged the Northern California dam’s main spillway…

Chinese companies and Chinese banks are now the biggest builders and financiers of global dam building. Chinese banks and companies are involved in some 307 dams in 74 different countries, particularly in Africa and Southeast Asia, including Kamchay Dam (Cambodia), Bakun Dam (Sarawak, Malaysia), Myitsone Dam (Burma) and Merowe Dam (Sudan).

Taking Down Dams and Letting the Fish Flow

elwha-dam
Elwha Dam removal, 2011. The largest dam-removal project in U.S. history—the Elwha River Restoration Project—commenced during the second week of September 2011, when National Park Service contractors began to dismantle two dams on the Elwha River in Washington State. The 32-m-tall Elwha Dam and the 64-m-tall Glines Canyon Dam, completed in 1913 and 1927, respectively, have been blocking the natural supply of sediment to the lower river and coast and severely limiting salmon and steelhead spawning for nearly a century.

Excerpts;

Nationwide, dam removals are gaining traction. Four dams are slated for removal from the Klamath River alone in California and Oregon by 2020.

Just a few of these removals have occurred on such large rivers, which play an outsize role in coastal ecosystems. But the lessons are the same everywhere: Unplug the rivers, and the fish will return…

dam-emissions-petit-saut-reservoir
Dire Consequences of Dam Reservoir Emissions, Petit Saut Reservoir, French Guiana. A growing number of scientific studies indicate that reservoirs, especially in the tropics, are a significant source of global greenhouse gas pollution. The “fuel” for these emissions is the rotting of organic matter from the vegetation and soils flooded when the reservoir is first filled. The carbon in the plankton and plants that live and die in the reservoir, the detritus washed down from the watershed above, and the seasonal flooding of plants along the reservoir fringes, ensure that emissions continue for the lifetime of the reservoir.

China May Shelve Plans to Build Dams on Its Last Wild River

The Nu/Salween River is one of the region’s last largely free-flowing rivers and is shared by China, Thailand, and Burma. The river originates on the Tibetan Plateau and flows through China’s Three Parallel Rivers World Heritage Site, before becoming the Salween in Burma and Thailand and emptying into the Andaman Sea.

Springing from Tibetan glaciers and flowing through China, Myanmar and Thailand, before spilling into the Andaman Sea, the Nu River- the last free-flowing river in China- could become a national park, as officials appear to back away from a proposal for multiple dams…

Rural Community Fights a Second Dam and a New Expropriation of Land, Mexico

“There are 4,500 dams in Mexico, 700 of which are large dams. 80% of reservoirs are polluted with industrial, agricultural and residential waste and many are high in sediment accumulation. Close to 180,000 people have been displaced by dams in Mexico;” 11-09-2012. Captions: International Rivers

Excerpts;

In 1976, the construction of a hydroelectric dam destroyed farmland in the rural municipality of Chicoasén in southern Mexico. Forty years later, part of the local population is fighting a second dam, which would deprive them of more land.

The 240-MW Chicoasén 2 dam, to be built at a cost of 300 million dollars, is scheduled to come onstream in July 2018.

The Chicoasén 2 environmental impact study says the dam will directly affect five communities in the municipality and will indirectly affect another 10. It also acknowledges that the dam, the reservoir and the hypdropower plant will hurt the landscape, wildlife and surface drainage…
