1983
Benthic macroinvertebrates were collected at two-week intervals between 1982 May 13 and August 18 at 16 sites along an 85 km stretch of the Athabasca River between Fort McMurray and the Ells River. Samples were collected from gravel bars with a 0.l m2 cylinder sampler. All netting had a mesh...

Geesy, G. G., Costerton, J. W.
The direct epifluorescence method has been adapted for counting bacteria in the sometimes turbid water of the Athabasca River and this method has been used to quantify planktonic bacteria. Monthly samples over an annual cycle beginning in May 1976 showed this population ranged from 1 x 105 to 2...

Alberta Environment, Hydrology Branch
This report identifies historical, annual and open water, low flow sequences for 13 stations in the Athabasca River Basin. Frequency curves are developed which provide an estimate of droughts of a specified exceedance probability. Drought events recorded on the Athabasca River below McMurray...

Alberta Environmental Protection, Technical Services and Monitoring Division
This study was undertaken for the Technical Committee, Canada-Alberta Flood Damage Reduction Program in response to concerns raised by the City of Fort McMurray over the validity of the elevation established in previous studies as representing the 1 in 100 year design flood level. The specific...

Cation exchange due to the diffusion of ammonium from livestock effluent through glacial clay soils
Download2007
Abstract: The objective of this study was to experimentally simulate interactions between liquid manure and soil in diffusion-dominant areas beneath earthen manure storage (EMS). A previous radial diffusion cell method was modified to include an anaerobic chamber that employed a plastic glove bag...

Sprague, J. B., Holdway, D. A., Stendahl, D.
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...

Enhancing productive capacity in the Canadian Arctic: Assessing the effectiveness of instream habitat structures in habitat compensation
Download2004
We examined the effectiveness of physical habitat structures (ramps, V-weirs, vanes, and groins) at increasing the productive capacity of a newly created 3.4-km artificial stream in the Barrenlands region of the Northwest Territories, Canada. We quantified changes in fish density and growth in...
