Description

The report evaluates longitudinal trends in benthic invertebrate and epilithic algal communities sampled from long-term river network sites on the Bow River in 2006. It also compares long-term trends in historical (1983-1992) and 2006 data. Responses to nutrient enrichment are clearly visible below Calgary: invertebrates and algae thrive in fast flowing (erosional) areas, but in slow flowing (depositional) areas lower diversities indicate stress. At Cochrane invertebrates and algae are impacted by strong diurnal fluctuations in river discharge resulting from hydro-electric dam operation.

Description

The primary objective of the study was to provide a summary of the diet data and any major patterns in the diet of fish from waterbodies within the study area. The analysis included the three diet content methods used (frequency of occurrence, percent composition by count, and percent composition by weight; see Section2.1 for details) and presentation of temporal (years and where appropriate months) and spatial patterns for the fish species among the river systems.

Description

This report presents the results of 1986-88 Bow River water quality monitoring programs conducted by Alberta Environment. Plant nutrient, coliform bacteria count and aquatic plant biomass trends and differences between sites were analyzed. This program was mainly designed to detect changes in river water quality since the installation of phosphorus removal at Calgary sewage treatment plants in 1982-83.
