Vanadium concentrations of 2.4 to 5.6 mg/L were lethal in 7 days to rainbow trout of wet weight 1.2-6.2 g. The LC50 varied slightly over the 12 combinations of water quality, from hardness 30 to 350 units and pH 5.5 to 8.8. The 7-day LC5O may be estimated by the following equation, which...

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...

1985
The objective of this report is to summarize water quality constituents in the AOSERP study area and to examine relationships between these constituents and changes in land formation, hydrology, and development. Summaries of routine parameters, nutrients, and metals are presented for sampling...

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...

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...

Preliminary recommendations for mapping of aquatic habitat parameters for the AOSERP study area
Download1978
Brown, A., Robarts, R. D., Kent, M. J., Park, J. O.
Three aspects of aquatic habitat assessment and mapping have been considered. The first aspect was the review of the parameters which characterize aquatic habitats in the AOSERP study area. From an extensive list, ten parameters for each of lake habitats and river habitats were selected as being...

Water quality of the Athabasca oil sands area Vol I
1980
This report documents locations of Athabasca Oil Sands area water quality sampling sites; sampling, analytical and quality control methods used; the volume and availability of assembled data; and an extensive appraisal of the quality of the data base. The quality control measures taken proved to...

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....
