Description

This wildlife status report looks at the western blue blag, which is the only species of iris native to Alberta. Distributed primarily in the western United States, it penetrates Canada along the southeastern flanks of the Rocky Mountains in Alberta. It is considered rare in Canada and is currently designated as Threatened nationally. This report is intended to summarize the existing information on the species in Alberta to assist with assessment of its status. It is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.

Description

Alberta Envrionmental Protection has intensively monitored the Bow River ecosystem since 1989. This work was designed to determine the distribution of contaminants from the Canada Creosote site in the aquatic ecosystem, to protect domestic water supplies and to ensure the human consumption of fish was safe. This report evaluates changes in water quality over the two years since the containment system was intalled.

Description

This wildlife status report looks at the long-billed curlew, the largest shorebird, and the most southerly breeding curlew, in North America. Once abundant over most of the prairie regions of the United States and Canada, populations have declined throughout most of the its breeding range since the early 1900s as a result of both overhunting and habitat loss. It is currently on the list of species that may be at risk of declining to nonviable population levels in Alberta. This report is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.

Description

A water quality study was initiated on the Red Deer River to address water quality concerns experienced by the Anthony Henday Water Treatment Plant during periods of runoff. The study was designed to document longitudinal changes in water quality in the Red Deer River between the Dickson Dam and the City of Red Deer, and to evaluate the effects of contributions from the Little Red Deer and Medicine rivers on Red Deer River water quality during spring runoff.

Description

In view of potential coal mine development in the Mountain Park area of the upper McLeod River and upper Cardinal River basins, Alberta Environmental Protection carried out a one year sampling program to obtain baseline data on water quality and benthos in the project area which would serve to complement and corroborate data being collected by the proponent. This report provides basic information on the methods used and compiles the data obtained during the program.

Description

Management of environmental toxics is a major issue on the environmental policy agenda in Canada and around the world. There is growing evidence that long-term, low-level exposure can occur from the atmospheric transport of pollutants over long distances and that the substances are associated with effects on human health and the environment. No region, however remote, is assured of being safe from airborne toxic pollutants. Recognizing the significance of air toxics, it is important to document the Alberta air toxics management program. This document presents an overview of the existing management system for controlling industrial air toxics emissions.

Description

This study delineates flood hazard areas and determines design flood levels along Lamont Creek and two unnamed tributaries through Lamont. The study area includes an approximate 6 km reach of Lamont Creek and almost 3 km of combined tributary stream length. The design discharge for Lamont Creek ranges from 11.2 m³/s at the upstream study extent to 16.6 m³/s at the downstream extent, with the design discharge through Lamont between 12.7 m³/s and 13.0 m³/s. The design discharges for the upstream and downstream tributaries are 1.5 m³/s and 5.4 m³/s respectively. The study was prepared in March 1998. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.

Description

This report summarizes the information gathered on the water quality of Field Lake during the initial period of study (1981 - 1986) and from three sets of samples collected during the summer of 1997. The impact of the effluent discharge is assessed by comparing 1) water quality two years before and four years after the discharge began, 2) concentrations of substances in the lake water with relevant Alberta and Canadian water quality guidelines, and 3) 1985-86 data with 1997 data.
