. It helped open up the area and supplied the power required during the construction phase of the project. In the planning stage, however, it became apparent that greater efficiency in the production of electricity could be achieved by diverting the flow of water from the Ossokmanuan Reservoir into the Smallwood Reservoir.https://nalcorenergy.com/wp-content/uploads/2016/12/Twin-Falls-Q1-2016-ISSUED-FINAL.pdf Utilizing this water at the Churchill Falls plant enabled approximately three times as much electricity to be produced from the same volume of water. In July 1974 the Twin Falls plant was put into extended shutdown and the water diverted into the Smallwood Reservoir under an agreement with Churchill Falls Labrador Corporation Limited (CFLCo).
