    3,400 earthquakes in hubei during 10 years time. what happens if an 7.0+ earthquake cracks the dam itself? all of wuhan would probably be washed away. probably won’t do much good for social order.

    looks like the curse of li peng offends not only the people but even the heavens and the earth.

    The dam’s benefits outweighs its shortcomings by a hundred folds. With the dam it has saved many lives and properties from flooding ,huge storage of water for shipping and irrigation, shipping is much better, et al. Many fish has prosper from this dam.

      How did the fish prosper? many fish are used to seasonal trips up-river to lay eggs, it is not that they can suddenly jump 200 meter up to take the hurdle of the dam, so those trips are a thing from the past.
      (just wondering, no criticism of the dam itself)

      • Greencar

        The dam uses fish ladders for the fish to migrate, the water level has been also more consistent and cleaner with very strict anti dumping on the rivers and tributaries.

          Thanks for the explanation, I’ll try to find more info on the fish ladders. I wonder how fish find them.

            I am a fishery biologist, I spent three months in China not too long ago, the fishery in that area has changed a bit but for the better. More water and cleaner water also is a big key.

    Thanks for the technical description of the complexity of the consequences of the Three Gorges Dam. Very interesting.

  • Greencar

    Many of the fish are adapting to the changes brought about by the dam positively. Most are doing quite well contrary to what Green Peace says. Those fish ladders are working quite well.

  • Greencar

    Initially the fish ladders did not work well but the fishes are using them more and more now as they are getting acclimated to them . During migrating periods you can actually see the fishes migrating up the ladder during the spawning season and down the ladder during the trip to the sea. I was told also that some fish became landlocked and adapting accordingly.
