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...

A regular program of water quality sampling has been instituted throughout the region of current oil sands development in northeastern Alberta. The goals of this program were to provide a base of background information on an extensive number of water quality parameters to enable the employment of...

Griffiths, W. H., Walton, B. D.

A review of the effects of sedimentation on aquatic biota is presented. The detrimental effects of increased suspended and settled sediments on fish, bottom invertebrates, and primary productivity are documented. It is shown that the upper tolerance level for suspended sediment is between 80-100...
