Large numbers of waterfowl, especially canvasback (Aythya valisineria), used Western Stump Lake as a staging area during most of October 1985. Selection of the lake as a conditioning site by this species likely is caused by extensive, shallow-water beds of sago pondweed (Potamogeton pectinatus) and lack of human disturbance. A brief limnological and historical account of the lake is provided.
