- The Shellmouth Reservoir (also known as Lake of the Prairies) is a man-made reservoir on the Assiniboine River in Manitoba and Saskatchewan, Canada. The Shellmouth Dam (50°57′49″N 101°25′07″W / 50.96361°N 101.41861°W) is a multi-purpose, embankment dam built by the Prairie Farm Rehabilitation Administration (PFRA). The dam and reservoir are part of a strategy to reduce the risk of flood damage for Winnipeg and other communities along the Assiniboine River. For example, in the 1997 Red River flood, the inflow to the reservoir peaked at 10,000 cubic feet per second (280 m3/s) while the outflow never exceeded 1,700 cu ft/s (48 m3/s). The reservoir is also used to supplement flows on the Assiniboine when conditions are dry, ensuring water supply for Brandon, Portage la Prairie, irrigators, and some industries. For example in early August, 2021 the flow in Brandon was a little over 9 cms while the outflow from Shellmouth was 5.7 cms and inflow was less than 0.5 cms. Therefore without the dam the flow in the Assiniboine at Brandon would be a bit under 4 cms. Asessippi Provincial Park is established around the southern arm of the lake. (en)
