Determine changes in the input rate of atmospheric trace substances into sensitive ecosystems and provide a database for the documentation of variations in chemical characteristics of precipitation
Resource
Monthly flows are provided for the period 1912 to 1980 at 21 locations on the Athabasca River and its major tributaries. The flow data sets are suitable for water management planning
Resource
Nearly 76% of all water used in the basin in 1981 was obtained from the river, 22% from major tributaries and other surface sources, and the remaining 2% from groundwater

Once the composite model is calibrated and tested, it would predict mass loading or concentration of a parameter at any point along the study area for different future development scenarios
Resource
Pesticide Chemicals Branch of Alberta Environment conducted a monitoring program in 1979 related to two methoxychlor treatments of the Athabasca River for black fly (Simulium arcticum) control.
Resource
The use of methoxychlor in the Athabasca River to control black fly (Diptera: Simuliidae) larvae was monitored in 1980. Effective control of black fly was observed for a distance of 60 km
Resource
Population reductions of non-target organisms in the Athabasca River due to methoxychlor was limited for the May 20/21 treatment but was considerable for the June 19 treatment.

Changes in effluent loadings at the two pulp mills and an increase in river flows in the lower Athabasca Basin accounted for some noticeable improvements in water quality from that reported in 1990

No measureable air pollutant effect was observed on either vascular or lichen communities at any site even though significantly high tissue pollutant concentrations were documented within 10km of GCOS
