Evans, B. J., Neill, C. R.

The drainage system of the study area consists of a number of rivers draining from the west and from the east into the Athabasca River north of Fort McMurray, as well as a few rivers which join the Athabasca near Fort McMurray and drain areas to the south and east. Runoff from within the study...

Straka, A., King, P., Grainger, G.

The results of preliminary experiments on pre-germination treatment methods for nine selected native woody plant species are presented. The species investigated include Amelanchier alnifolia (saskatoon), Arctostaphylos uva-ursi (bearberry), Elaeagnus commutata (silverberry), Juniperus communis...

Wallis, P., Baker, B., Peake, E., Telang, S., Strosher, M.

Understanding the functioning of the aquatic ecosystem within the mainstem Athabasca River is of paramount importance if protection against the input of contaminants from oil sands developments is to be afforded to the Athabasca River itself, the Peace-Athabasca Delta, and Lake Athabasca. The...

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...

Griffiths, W. H., Walton, B. D.

A review of the effects of sedimentation on aquatic biota is presented. The detrimental effects of increased suspended and settled sediments on fish, bottom invertebrates, and primary productivity are documented. It is shown that the upper tolerance level for suspended sediment is between 80-100...

Strosher, M. T., Peake, E.

Organic constituents of wastewaters from the existing Athabasca oil sands extraction plant were characterized and quantified. Twenty-one chemical parameters were determined on a total of ten samples taken during November and December, 1975 from the tailings pond dike filter drainage system, the...

Wallace, R. R., McCart, P. J.

The information presented here reviews what is currently known of fish ecology and production of the Athabasca Basin, and includes discussions of fish production, sport and commercial use of fish populations, and alternative opportunities for recreational fishing in the rivers of the Athabasca...

Machniak, K.

The impact of saline waters upon freshwater biota, having special reference to the AOSERP study area, is reviewed. Available information on water quality in the AOSERP study area indicates that: the natural regional surface water quality does not appear to have any toxic effects, and chloride...

Westlake, D. W. S., Coutts, R. T., Nix, P. G., Pasutto, F. M.

In this study, the ability of microorganisms to degrade selected organic substrates in samples of Athabasca River water and water-sediment has been determined. Analysis of laboratory-incubated samples using gas chromatography/ mass spectrometry has shown that trace amounts (100 µg/L) of m-cresol...

Anderson, P. D., D'Apollinia, S., Perry, S., Dick, J., Deluca, J., Spear, P.

This study was initiated in early 1976 during the early stages of the Alberta Oil Sands Environmental Research Program. The goal of the project was the establishment of criteria safeguarding fish from toxic effects of mixtures of vanadium, nickel, and phenol to fish. All three constituents are...
