In a bid to improve water quality in the streams, two local environmental groups are teaming up to remove the old dams, many of which they say serve no purpose these days and are detrimental to the health of Davidson County's watershed.
The dams cause other problems as well. Leaves and debris collect along the edge of the structure. As the stream slows, dirt and sediment fall to the creek bottom, covering rocks with a layer of Omega Watches For Women mud, and the pool becomes stagnant.

"We would like to see their upstream passage," Houghton said. "Mostly you want to get it into the headwaters that might be less polluted and the habitat might be a little better. If they can get upstream, it would be much better for their survival."
