Description

In 1996 harlequin ducks were added to the Yellow "A" list of endangered and threatened species in Alberta. Since 1995, research in Kananaskis Country has contributed significantly to an understanding of the habitat and conservation needs of harlequin ducks in the province. The objectives of the 2000 field season, the results of which are reported in this document, included investigating the abundance, population structure, survival rates, trends and productivity of harlequin ducks on the Elbow and Kananaskis rivers; continuing baseline work on the Sheep and Highwood rivers, and Cataract Creek; and to make recommendations regarding harlequin duck conservation.

Description

This study delineates flood hazard areas and determines design flood levels along an approximate 31 km length of the Highwood River through High River. The design discharge for the Highwood River ranges from 750 m³/s at the upstream study extent to 650 m³/s at the downstream extent. Included in the study area are lands flooded by overflow from the Highwood River into the Little Bow River via Baker Creek and the Little Bow Canal, along approximately 3 km of Baker Creek and almost 1 km of the Little Bow River. The flood hazard mapping in a portion of the overflow area and along the Little Bow River is currently under review by Environment and Sustainable Resource Development. The study was prepared in August 1992. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.
