1979
Seasonal and areal variations in significant water quality parameters in the Muskeg River basin of northeastern Alberta are described. Specific conductances and the concentrations of major ions (Ca+2, Mg+2, HCO3 -, and, to some extent, Na+ and Cl-) generally exhibited relatively stable seasonal...

Baseline states of organic constituents in the Athabasca river system upstream of Fort McMurray
Download1979
Investigations were carried out on the Athabasca River upstream of Fort McMurray to determine the baseline quantities of organic constituents and their contribution to the organic water quality of the river system as it continues through the Athabasca Oil Sands strip mining area. Results of these...

Interim report on ecological studies on the lower trophic levels of muskeg rivers within the Alberta oil sands environmental research program study area
Download1979
This project (AF 2.0.2) was conducted in 1977-78 as a planned complement of another project (AF 2.0.1) on invertebrate resources. The scope of this project was to investigate productivity in the oil sands region and it involved both baseline data collection and manipulation experiments....

Acute lethality of mine depressurization water to trout-perch (Percopsis omiscomaycus) and rainbow trout (Salmo gairdneri) Volume I
Download1979
Mine depressurization water obtained from five wells on Lease 17 held by Syncrude Canada Limited, was examined for chemical composition and acute toxicity to two species of fish. In the first series of experiments, mine depressurization water was diluted with various proportions of water...

Interim report on ecological studies on the benthic invertebrates of various rivers in the Alberta oil sands environmental research program study area, northeastern Alberta
Download1979
This report details preliminary experimental and survey research on benthic communities affected by selected hydrocarbons and tailings sludge produced by existing oil sands mining and upgrading operations. Taxonomic surveys of macrobenthic communities were carried out in the Muskeg and Steepbank...

Giles, M. A., Lawrence, S. G., Klaverkamp, J. F.
In order to conduct oil sands mining operations in the surface mining region of the Athabasca oil sands deposits, most regions require depressurization of the basal sandstone formations. The groundwater produced by depressurization operations is of poor enough quality to be toxic to fish. The...

Synthesis of surface water hydrology
1979
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...

Detailed studies of groundwater-surface water systems in Hartley Creek basin show the creek to be at baseflow for only a few months in the winter when other contributions to streamflow are negligible. Following spring snowmelt, drainage of muskeg is the major contributor to streamflow along with...

Aquatic biophysical inventory of major tributaries in the AOSERP study area. Volume I: Summary report
Download1980
This report summarizes and compares the physical characteristics of nine streams within five watersheds (Firebag, Muskeg, Steepbank, MacKay, and Ells) in the AOSERP study area. The distributions and relative abundances of fish in each stream and watershed are also described and related to the...

During 1977, the second year of a two-year study, the fish populations of the Athabasca Rive: were investigated in two general areas downstream of Fort McMurray. Field work was carried out from mid-April to early November in the Mildred Lake study area and from mid-May to mid-October in the Delta...
