Description

Cyanobacteria, often known as blue-green algae, are well adapted to growth in alkaline, nutrient-rich water bodies. During calm conditions, they can congregate near the water’s surface. These “blooms” are unsightly and produce objectionable odors, and can also induce skin irritation, itchiness and severe rashes upon contact. This pamphlet provides more information on the risks posed by cyanobacteria and steps to take to protect against possible harmful effects.

Description

This fact sheet provides information on the diagnosis and treatment of cyanobacteria in sources of surface water used for agricultural purposes. Blue-green algae, or cyanobacteria, are natural inhabitants of surface waters and are widely present in dugouts and reservoirs. However, they can become a problem when conditions promote rapid growth and eventual death and decomposition.

Review of benthic invertebrates and epilithic algae at long-term monitoring sites in the Bow River

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... More ≫

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 intensive monitoring of the Oldman River and its tributaries was conducted from April 1984 to March 1985. The study included chemical monitoring, biological monitoring of algae, macrophytes and benthic invertebrates, and testing for accumulation of metals and organic contaminants in the sediments. The establishment of baseline conditions indicate the current status of the basin, including the impact of present development. This forms a basis for comparison for any future impacts or developments.
