Site description The Whitewater Lake catchment basin is located in the southwestern corner of Manitoba, north of Turtle Mountain Provincial Park. It is an alkaline lake that may contain no water for two or three years at a time during dry cycles; during normal years it covers 6,070 hectares, but can be as high as 10,320 hectares (and two metres deep) during years with increased run-off. Over the past 100 years there have been several decades, such as the 1930s and 1980s, in which the lake was dry most of the time. Several small creeks drain into Whitewater Lake, but there is no major natural outlet. The flat terrain surrounding the lake is used for agricultural production. A small rare herbaceous plant (Heliotropium curassavicum) is found here. At the east end of the lake, Ducks Unlimited (DU) have constructed a number of dykes, creating basins that attempt to stabilize water levels for nesting and migrating waterfowl.
