But the unintended effects are serious, and in some cases are canceling the benefits; the lake effect is
reducing rainfall upstream, and in the event of a catastrophe, the flooding downstream would be unimaginably devastating.
The government blames low
rainfall levels, which are certainly a factor, but researcher Ye Xuchun told the paper that the dam 500 kilometers
upstream has dramatically
reduced flow levels on the Yangtze River, which is linked to the lake.
