Study of the fish fauna in the Muskeg River commenced in 1976 with the general objective of describing the baseline states of this resource in the watershed and providing a quantitative estimate

Migrations of non-resident fish from the Athabasca River into the Muskeg River watershed were monitored through the use of a two-way counting fence. 6153 fish passed through the upstream trap

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 from mid-April to early November

Results of work done in 1976, the first year of a two-year study intended to evaluate and describe the baseline state of the fish resources of the Athabasca River downstream of Fort McMurray

The fish populations of the Athabasca River downstream of Fort McMurray were sampled during the open-water period in 1976 and 1977. Twenty-seven fish species were identified from the Athabasca River,

This project, via field and laboratory tests, was designed to determine the limits to growth of native and non-native graminoid and woody species under moisture and nutrient stress conditions.

Comprehensive assessment of mixing characteristics of the Athabasca River below Fort McMurray under ice-covered flow conditions. Two tracer tests conducted and analysed using recent theoretical models

Aerial surveys and ground investigations were conducted in the spring and summer months from 1975 to 1977 on a breeding population of White Pelicans (Pelecanus erythrorhynchos) in the Birch Mountains

Describe basic ecology of aquatic benthic macrofauna of the Athabasca River and its major tributaries, the Muskeg and Steepbank rivers

Preliminary experimental and survey research on benthic communities affected by selected hydrocarbons and tailings sludge produced by existing oil sands mining and upgrading operations
