BIOSIS COPYRIGHT: BIOL ABS. This report constitutes Phase II of a two-part project designed to provide disclosure of the physical, chemical, and biological effects of the Churchill River diversion and Lake Winnipeg regulation on the aquatic environment. Specific geographical reference is made to the five communities signatory to the Northern Flood Agreement (NFA): Norway House, Nelson House, Cross Lake, Split Lake, and York Landing. Phase I of this study provided an initial compilation and synthesis of availble information relating to: water levels and flows; lake and river shorelines; erosion, sediment transport, and deposition; debris; ice; water chemistry; fisheries (including primary and secondary productivity); and mercury. Literature was reviewed hierarchically: first by community; second by physical, chemical, and biological effects; and third on a chronological basis. Socioeconomic effects were not included; neither was information from Southern Indian Lake (SIL) because the community was n
