Heres some info on Dickey Lincoln, it predated the web so there isnt as much info out there as some projects. Not mentioned in the test was that it was originally deisnged to support the Richmond Maine nuclear power plant that was never built along with the Wiscasset power plant whihc was built but since decomissioned. The project would run backwards during the night storing water and then would run the hydro during the day when there was a demand. Considering that a 950 MW combined cycle natural gas plant fits on about 10 acres and can be built in about 2 years, I dont see Dickey Lincoln coming back especially since the nature conservancy bought a bunch of the land that would have been inundated.
Since the 1930s, the Dickey-Lincoln School Dam Project on the St. John has been considered by the US Army Corps of Engineers. The project was authorized by Congress in 1965 and a full proposal was created in 1974. This project would have put in the Dickey Dam and the Lincoln School Dam to provide electricity during peak times. If constructed, the project would have generated over 800 Megawatts and would have provided about 17% of New England's peak energy during the 1980s. Churchill Dam would likely have modified its flow levels and times to maximize energy production at these sites. The project would have inundated about 88,000 acres of land and part of the St. John River. However, the Dickey-Lincoln project was not built because of controversies over energy at the time. The project had to meet new White House water resource policies at the time. Additionally, there was a lot of debate over the economic and environmental costs of the project for just peak energy production. The project concept was deauthorized by Congress in 1986. In addition, considerations for the Furbish Lousewort (Pedicularis furbishiae), an endangered plant, harmed the project. In 1976, Furbish Lousewort was rediscovered along the St. John during survey work for the Environmental Impact Statement for the Dickey-Lincoln Project. The banks of the St. John are still the only place where Furbish Lousewort is found today. The Army Corps worked with the U.S. Fish and Wildlife Service to create a conservation program that would allow the project to continue and allow for protection of Furbish lousewort. The two agencies agreed on a conservation plan that would allow Dickey-Lincoln to still be constructed while protecting the species through research, monitoring, protection of habitat, and establishment of new colonies. The Furbish Lousewort rediscovery is not what halted the project in the 1970s. In fact, the Fish and Wildlife Service stated that they "believe that if the conservation program is followed, it will result in an increase in numbers of the species and increased protection for its habitat." The Dickey-Lincoln project was recently brought under discussion again, but construction is not planned.
