Dumb dams?

When I read the title of the article from GE's ecomagination blog, I thought it was clearly a biased article against Eco-friendly hydro power. I was suprised when I read the following (referring to small hydro power):

"of the 80,000 dams in the country, only three percent currently create electricity."

Say what?? We have dams out there that are just wasting the opportunity to produce capital and contribute to cleaner air and we're not taking advantage of it!? What environmental extremists don't tell you is that "If managed well, small hydro could have little impact on fish and even improve a river’s health." Here's a great video that shows how positive of an impact small hydro power has for the environment and the home owner's pocket book.
