Siemonsen, D. J., Bothe, R. A.
A hydrologic parameter that has become synonymous with water quality evaluations of rivers is the term “7Q10”. This term represents the annual minimum 7-day discharge at a particular location along a river, below which flows would be expected to occur in only 10% of the years. The complement to...

The ecology of macrobenthic invertebrate communities in Hartley Creek, Northeastern Alberta
Download1979
McElhone, M., Crowther, R., Davies, R. W., Hartland-Rowe, R. C. B.
Hartley Creek, a tributary of the Muskeg River in the Athabasca Oil Sands area of northeastern Alberta, has a discharge ranging between 0.5 and 7 m3.s-1 , experiences temperatures ranging between 0° and about 18°C, and has high oxygen concentrations at all seasons. The benthic fauna is rich and...

Investigations of the spring spawning fish populations in the Athabasca and Clearwater Rivers upstream from Fort McMurray: Volume 1
Download1979
Fisheries investigations were undertaken in the spring of 1978 (28 April to 25 June) in the Athabasca and Clearwater rivers upstream of Fort McMurray. The major objectives of the studies were to determine what spring spawners utilized these sections of the Athabasca and Clearwater rivers; to...
