One only need to visit Lake Foul (Powl) to see how horrible a damn is to an ecosystem. Dams may extend some seasons as we see on the Platte (and I do love the long season) and on Gore, but in the long run they do nothing but harm to the environments they are created in.
The Grand Canyon, one of the most unique environments on the North American continent is being destroyed by the dams up-river. The natural flood and ebe that has formed and shapped the canyon has been serriously disrupted. Unique and endangered species are being lost every year due to the derth of nutrients and sediment that would normally be brought down by the spring floods. The dams cause most of the sediment to fall out of suspension and never reach the Grand. The water comming out of the bottom of the dam is far colder than it would be naturally at that point; this does some pretty horrible things to native fish populations as well.
Then there's the issue of waste. By stopping water in one place in a big pool, you increase the surface water exposed to sun. This water evaporates. Billions (that's right, BILLIONS, with a B) of gallons of fresh water are lost every year to evaporation from dams in the desert. They also waste the natural resource of the location. None of us who are reading this post will EVER see Glenn Canyon in our lifetimes. It is GONE forever. That is a terrible, terrible price to pay so that we can have a place to run our speed boats and have green lawns in the middle of the Tuscon desert.
Instead of new water projects (spelled DAMS), what we need is more responsible water management. We don't need more water, we just need to use what we have more wisely. We don't need more blue-grass lawns and 2 hour showers.
Please, save Colorado from more debt, more environmental degridation and more dams, Vote no on A.
