Chemical, Physical and Biological Effects of
Lake Winnipeg Regulation and Churchill River Diversion on the Aquatic Environment
North/South prepared a report outlining the chemical, physical, and biological effects of the Churchill River Diversion (CRD) and Lake Winnipeg Regulation (LWR) on the aquatic environments of the five native communities signatory to the Northern Flood Agreement. The report included a compilation and synthesis of all available information relating to: water levels and flows; lake and river shorelines; erosion, sediment transport, and deposition; debris; ice; water chemistry; fisheries; and mercury.
Pre- and post-project databases for each of the affected communities (Cross Lake, Split Lake, Nelson House, Norway House and York Landing) were summarized and rated for level of completeness. Information gaps were identified and the effects of LWR and CRD were documented. This information was submitted in a final report to the Department of Fisheries and Oceans who had contracted the study.
