Description

The report describes the fish community of the Oldman River between the Oldman River Dam and the confluence with the Bow River, based on the results of field sampling conducted in 2012. Assessment of the fish community was completed as part of the Oldman River Dam environmental monitoring program. Monitoring was intended to determine the environmental impacts of the construction and operation of Oldman River Dam and the effectiveness of environmental mitigation measures. In 2012, the fish community in the Oldman River was similar to the pre-dam fish community, but the range of fish had likely shifted downstream in response to changes in flow and water temperature. Stocked brown trout persist, but additional work is needed to determine if a sport fishery has developed.

Chloride in surface waters of Alberta’s rivers : condition of the environment report 2021

Description

This report presents the methods used to generate the web-based Condition on Environment (CoE) content published for chloride (Cl-) concentrations in the surface water of major rivers and their... More ≫

Description

This report presents the methods used to generate the web-based Condition on Environment (CoE) content published for chloride (Cl-) concentrations in the surface water of major rivers and their tributaries across Alberta. Accordingly, this report helps fulfill the responsibility of reporting to the public on the condition of Alberta's ambient environment, as required by the province's Environmental Protection and Enhancement Act. In particular, this report outlines the steps taken to obtain and prepare the data, assess the quality of the data and conduct spatial and temporal analyses of Cl-. The goal of this report is to neither investigate nor summarize potential Cl- sources, but rather to summarize spatial and temporal trend of Cl- concentrations in the surface waters of Alberta's major rivers and tributaries.

Description

The Crowsnest River became a provincial priority to understand the impact of whirling disease on rainbow trout populations, prompting a comprehensive study of the watershed in 2019. Results of the study are contained in this report. The objectives of this study were to: determine the spatial distribution, infection prevalence and severity of Mc in the Crowsnest River; measure triactinomyxon density in free-flowing water; characterize oligochaete relative abundance throughout the Crowsnest River; measure the timing and location of optimal water temperatures for parasite development and transmission; and estimate density and age-class structure of juvenile rainbow trout. The Crowsnest River is a high-value sport fishery in southern Alberta.

Description

This GIS dataset covers the four types of decontamination zones for whirling disease in Alberta, and identifies the inherent risk categories for each. These boundaries are to be used by Government of Alberta field staff and industry, as described in the Alberta Decontamination Protocol for Watercraft & Equipment. (1) Confirmed Red Zones are zones with CFIA confirmed positive testing for whirling disease and are based on a 'HUC 10' level as found in the Hydrologic Unit Coded Watersheds of Alberta dataset. Irrigation Red Zones are similar to confirmed red zones, however are based on Irrigation District boundaries and only apply to irrigation canals. (2) Yellow Zones represent high to moderate risk for the introduction/spread of whirling disease due to one or more of the following criteria: susceptible salmonid species present, high recreational activity/use and access to water, and high population base. (3) White Zonesdo not have any confirmed cases of whirling disease and...
