you can read the full story at the link. this is some funny stuff. way to much water kills salmon. and makes to much power at the dams.

The manager of most of the electricity in the Pacific Northwest is running such a surplus of power from hydroelectric dams that it put wind farms on notice Friday that they may be shut down as early as this weekend.
The main culprit for the wind slowdown is spring weather that followed a winter with heavy snow in the mountains feeding the Columbia River basin. The spring surge is expected to be the largest since 1997.
When water levels are this high, the agency said, it has no choice but to use the water to generate electricity in hydroelectric dams. Laws protecting endangered species prevent it from sending all the excess water through spillways and around the dams. That beats up salmon and steelhead. It also creates so much nitrogen gas bubbling in the water that the fish get the equivalent of the bends.
Grid operators say they have run out of capability to sell the surplus electricity, store the water or shut down gas, oil, and nuclear plants — leaving wind farms the unfortunate victim.
The financing of many wind farms relies on tax credits that are of benefit only if electricity is produced. And the decision could set the stage for even more significant fights in the years to come if the Northwest wind industry doubles its capacity, as projected, over the next decade.
