Description

This report identifies historical, annual and open water, low flow sequences for 13 stations in the Athabasca River Basin. Frequency curves are developed which provide an estimate of droughts of a specified exceedance probability. Drought events recorded on the Athabasca River below McMurray with an exceedance probability greater than 0.90 are identified and discussed. The analysis provides low flow information which can be used to determine general management guidelines for the Athabasca River Basin.

Description

This report discusses channel improvement alternatives along Cardinal Creek, with the objective of providing flood relief so that the floodplain lands can be used for agricultural purposes. Several alternatives are examined, with the 1:10 year return flood as the design discharge. It was found that the work required to increase the channel capacity to the 1:10 year flood discharge would cost in excess of $1 million. It is, therefore, recommended that all beaverdams and abandoned bridges be removed completely from the creek, and that the channel be cleared of brush. With these works, the extend and frequency of overbank flooding would be reduced significantly. Clearing and brushing would be required annually.

Description

This report and accompanying soil maps describe the characteristics, distribution, and use limitations of the soils in the Iosegun Lake area in north-western Alberta. As part of the program to inventory Alberta's land resources at a reconnaissance scale, this soil survey provides baseline data for general land use planning. A brief treatment of the geology, history, climate and vegetation of the area is presented as background information to a general understanding of the landscape. The complete report consists of the written text and four soil maps. Soil units are identified on the map, and are described briefly in the legend, and at a greater length in the text in terms of the landscape and environments where they occur. Discussion on use and management of the soils is included. Ratings of soil suitability for agriculture, forestry and selected engineering uses are included.
