They took people’s land without permission for their own economic gain. They claimed eminent domain, which isthat they could do it for the public good.o Economics have said that the dame would not produce the amount of money that they thought it would.o The common people of these lands tried to fight the dam with the Endangered Species Act because of the snail darter, but they failed. The people for the dam wrote a hidden amendment into the law granting Telico exemption from all federal law. o The snail darter species proved to be a survivor. They were found in other areas of the Little Tennessee River after the dam was completed. This species was originally discovered in 1973. In 1984, this species went from endangered to threatened.o Several areas were buried and flooded. They are the following: Cherokee: Archaeological Hotbed, prime farmland (usually in creeks and river floodplains), and wetlands and wildlife, including fish. - Pigeon Rivero A project occurred to help the Pigeon River. This project was called Pigeon River Recovery Project: Restoring Aquatic Diversity. These notes represent a detailed interpretation of the professor’s lecture.

They poured their waste into this river called point source pollution. Toxic chemicals include dioxins, furan, and chloroform. Toxic effluent extirpated, or locally diminished, all snails, mussels, and most fish species. o It was owned by Champion, but the employees bought it. Then, another company called Evergreen bought the mill. The employees actually wanted to stop polluting this river.o In the 1980’s, this sparked controversy between Tennessee and North Carolina. The EPA had to step in. The color of the river improved from “coffee” to a “weak tea.” The level of dioxins in fish dropped low enough that authorities rescinded most of the fish consumption advisories. o They diverted a 12 mile section of the Pigeon River at Walter’s Dam. 6 miles of this section runs through a tunnel to a power plant. o The first step of this project was to modernize the mill machinery.o There were several missing species because of the pollution. All native mollusks, approximately 40 mussel species, and approximately 10 snail species were missing.o Then, they had to test the waters. During the 1990’s, they placed snails in the river to see if they could survive and reproduce. They found that they indeed could. Left-handed snails are tolerant to pollution, while right-handed snails need “right,” or clean, water. They introduced several species to help build the community.These notes represent a detailed interpretation of the professor’s lecture.
