Muskrat Falls was a natural 15-metre (49 ft) waterfall located on the Churchill River about 25 kilometres (16 mi) west of Happy Valley-Goose Bay, Labrador. The hydropower potential of Muskrat Falls was recognized in the early 1900s when the Grand River Pulp and Lumber Company proposed to build a dam along with a paper mill. Neither was ever constructed. In the early 1970s an engineering and geotechnical survey was carried out to determine the hydro potential of the site. The site will be developed as part of the Lower Churchill Project, despite concerns of methylmercury poisoning by researchers and local Inuit.
