Description

The report is organized into two parts. Part one contains brief technical summaries of methods used to establish instream flow needs determinations in the South Saskatchewan river basin that provide for full protection of the aquatic environment. The purpose of summarizing these techniques within the following document is to provide a basis for the methodology used to evaluate impacts from alternative flow management scenarios. The second part of this document then explains the impact ratings methodology and demonstrates its application using example flow management scenarios applied to seven reaches of the Red Deer River.

Description

This report addresses two issues concerning the bacterial quality o the lower Red Deer River: 1) the increase in fecal coliform counts and incidence of non-compliance with water quality objecgives set by the Prairie Provinces Water Board (PPWBO) at the Alberta-Saskatchewan border, 2) the implications of discontinuing chlorine treatment of the Drumheller, East Coulee and Rosedale final municipal effluents on bacterial quality of the Red Deer River.

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

Temperature and dissolved oxygen (DO) are important water quality variables which affect the viability of fish and other aquatic organisms. These variables can potentially be influenced by river flow. Understanding the effects of flow and other factors on these important variables is critical for river management, particularly in the face of increasing demands on river resources. In this report, simple empirical methods are used to investigate the relationships between water temperature, DO, air temperature, and flow at two locations in the Red Deer River. Available water temperature, DO, discharge, and air temperature data were compiled for a number of sites along the Red Deer River. Compliance with water temperature and dissolved oxygen requirements for fish were evaluated at all sites using daily data. Non-compliance with acute and chronic temperature criteria occurred more frequently at stations located in the lower reaches of the river. Violations of oxygen criteria in the...

Description

This report is an initial attempt to understand why fecal coliforms, copper, zinc, lead and iron do not meet Prairie Provinces Water Board Objectives on some occasions in the Red Deer River at Bindloss, Alberta, the PPWB long-term monitoring site.
