A fisheries and water quality survey of ten lakes in the Richardson Tower area, Northeastern Alberta. Vol I: Methodology, summary, and discussion
A fisheries and water quality survey was conducted in September 1979 on 10 small lakes (67.4 to 338.9 ha) in the vicinity of Richardson Tower, approximately 140 km north of Fort McMurray, Alberta. The major objectives were: (1) to determine morphometric and water quality characteristics in relation...
