## Churchill River Diversion

The Churchill River Diversion of the Nelson River Hydroelectric Project diverts part of the Churchill River at Missi Falls, the natural outflow of Southern Indian Lake, south into the Rat River branch of the Burntwood River. The control dam at Missi Falls (Missi Falls Control Structure) raised the lake level 3 metres. An artificial outflow channel (South Bay Diversion Channel) was also created from South Bay of Southern Indian Lake to Issett Lake. The dam at Notigi (Notigi Control Structure) on the Rat River controls the flow to the Nelson River system.
