Abstract: Construction of hydroelectric stations began on the lower Nelson River in 1966, and has had to contend with long, severely cold winters and river ice jams up to 15 m thick. Three plants, Kettle, Long Spruce and Limestone, have now been completed and provide almost 3600 MW of power to Manitoba. The fourth plant, Conawapa, is scheduled to start construction within two years. The methods that have been used to deal with the severe river ice problems are discussed. The strategy has been one of constructing very high cofferdams to protect against the high winter water and ice levels, and to pond and control the level of the fore bay in the later stages of river diversion through the concrete structures.
