Identifying the impact of altered flow regimes on Milk River populations of Mountain Sucker

Fisheries and Oceans Canada (DFO) provided $141,708 in funding through the partnership fund to the University of Alberta for a project that examines how changes to water levels in Milk River, a river in southern Alberta, affects the suitability of this habitat for Mountain Sucker, a species listed as Threatened by COSEWIC (Committee on the Status of Endangered Wildlife in Canada). The study looks at the effects of water levels on the fish's growth and reproduction rates, and its ability to navigate the river. The results will provide information on population viability and how Mountain Sucker respond to changes in flow regimes.
