Abstract: The southward diversion of_the Churchill River from Southern Indian Lakealong the valleys of the Rat and Burntwood rivers to Split Lake,on theNelson River,is part of the ongoing hydroelectric development of theNelson River.Between the 24,200 km²Lake Winnipeg and Hudson Bay,theNelson River drops 219m over a distance of 680 km with a theoreticalpover potential of 5300MW or 46,500 GWh,based on a mean annual flov of2480 m³/s. The river is characterized by bedrock-controlled reaches,lakes and spectacular rapids. The large amount of energy available,combined vith the possibility of obtaining complete flow regulation vitha relatively smail control structure on Lake Winnipeg,provides analmost ideal site for a large hydroelectric development.
