I have to agree with you all in that dams can dramatically reduce fish counts. However, one must reason why these dams have been placed on rivers to begin with. A large majority have been placed on rivers to produce electricity for our homes. The national trend right now indicates that the USA will encounter a SERIOUS shortage of electrical power within the next 10 years or so.
We have to consider alternative choices to these dams for supplying electrical power. Can you say nuclear or fossil fuel? Take a look at the environmental impacts these two choices make on our precious environment. Personally, I feel the nuclear plants produce much less FISH reduction in our streams, but the obvious delema of nuclear waste will always be a serious issue. Fossil fuel plants pump tons of acid-rain producing compounds into the air which ultimately makes its way into our streams.
With all this said folks, I think we must make a choice for our future taking into account how we can better serve our fish runs. I don't think we can just conclude that damns NEED TO GO without thinking of the repercussions on ourselves first. This is how most Liberals think.....get rid of something so they PERSONALLY can benefit from it, irregardless of the repercussions on everyone else!
