Description

To inform future land use planning in the Eastern Slopes of west-central Alberta, a review was conducted of key land use stressors and expected ecological responses. Altered fire regimes, forest harvesting, and linear disturbances are key stressors that, along with climate, and other environmental drivers, affect wildlife, hydrology, and other valued ecosystem attributes. The current status of each stressor in the study area was characterized from geospatial and other environmental datasets, expected ecological responses were summarized from reviews of the published literature, and future research and monitoring priorities were identified.

Description

This report documents the configuration, calibration and validation of the river water quality model for the mainstem of the NSR from Devon to the Alberta-Saskatchewan Border. The model represents hydrodynamics, water temperature, dissolved oxygen, organic carbon, nutrients, algal interactions and other parameters influenced by tributaries, municipal wastewater treatment plants, industrial facilities, combined with sewer overflows and storm water. The model calibration period was from January 2000 through March 2008.

Description

Over the past thirty to fifty years, major rivers throughout the province of Alberta have been undergoing regular monthly sampling for a wide range of water quality parameters. Known as the Long-Term River Network (LTRN), this monitoring initiative has resulted in an extensive database of water quality information for the Province. Due to the broad time span and continuity of these data, they lend themselves particularly well to statistical trend assessment – a very useful way of examining changes in the health of a water body over time. Often indicative of human activities in the basin, trends in water quality parameters can be analysed for a variety of purposes, including the evaluation of human impacts on water quality, the development and assessment of watershed management initiatives, and the prediction of future conditions. The purpose of this report was to assess water quality conditions and trends in the North Saskatchewan River from 1977 to the end of 2002.

Water quality in the North Saskatchewan River is monitored for the Prairie Provinces Water Board (PPWB) at the Alberta-Saskatchewan border. Occasional exceedences of PPWB objectives for copper,... More ≫

Description

Water quality in the North Saskatchewan River is monitored for the Prairie Provinces Water Board (PPWB) at the Alberta-Saskatchewan border. Occasional exceedences of PPWB objectives for copper, fecal coliform bacteria, zinc and lead prompted an investigation into sources that may contribute to these high concentrations. Historical water quality data are available for point sources and the river in the urban area, but little is known about the contribution of the creeks and point sources discharging to the river along the last 100 km of river before it reaches the border.

Description

This study provides a first step in assessing effects of storm and combined sewer discharges on water quality in the North Saskatchewan River. Results generally confirmed conclusions from other studies conducted by Alberta Environmental Protection and the City Of Edmonton that these discharges are a significant source of pollutants to the river during wet weather.

Description

The objective of this report is to present historical information and data concerning the floods int he North Saskatchewan River Basin. It is the intent to provide in one report the most salient flood data and information which may be available in any of the several existing publications. There are currently about sixty hydrometric stations active in the North Saskatchewan River Basin. This report presents data for eighteen selected hydrometric stations. Streamflow data have been collected for the North Saskatchewan River for approximately seventy years and there are several publications which give the recorded flood data in various forms.
