Carbonton Dam is a dam no more – a small hydroelectric dam built in the ’30’s, this dam was no longer useful – it generated only a tiny amount of power and very little profit. Its owner began to let it slide, letting it sit unused.
Restoration Systems saw this as an opportunity to bring back an ecosystem that had long been choked by the dam – dams cause disruption in aquatic animals’ life cycles, population, and movement, and usually make changes to the water and plant life nearby, in addition to drowning a portion of land nearby. This one was now only useful as a good place to fish for bass – which caused some conflict with the local populace, who did not want to lose their favorite fishing hole when the company first proposed taking out the dam. Restoration Systems and its partners, including UNC, did a lot of education and discussion before actually beginning the project to get local people on board as much as possible.

Restoration Systems is a company – almost entirely made up of UNC grads – that corrects or restores water systems and then sells credits for doing so to developers. Developers are required to do something to mitigate any damage they have caused to the environment with their developments by purchasing remediation credits. This often means wetlands restoration, but in this case this company decided that it wanted to focus on this small obsolescent dam, one of approximately 1000 in North Carolina.
They studied the situation, went through months to request the proper permits from the state, and began by notching holes in the dam, to allow some of the water to flow through. They continued expanding the notch over five months, to allow the waters to mix – they couldn’t let it through all at once not only because of the negative effects of a large rush of water suddenly hitting the land on the other side, but to maintain the oxygen and mineral balance on both sides.

It now has one tall building on one side, with a ladder roped off and a platform to one side. When you stand on it, you can see the inside of the former dam – it still has caked dried silt at the bottom of the large empty chambers. the other side of the river flows freely through, and is a definite success. The project managers told us that two populations of rare fish on each side have now mingled and increased to large degree.

The bass fishers actually have better fishing in their newly returned river, although they now must use canoes. The company also created a small public-use park to the side of the river nearest the road, replacing a mass of scrubby weeds – everybody won. Including us – we had an excellent barbeque picnic, sponsored by Restoration Technologies. I have never before liked baked beans, but these were excellent. They also had great brownies. This is turning into a food blog – I’m really not obsessed, they’re just feeding us very well!
I will write up our third stop and our very pleasant evening dinner with the NC State folks on their own bus tour tomorrow.
