The Delta Marsh Field Station is a research and teaching facility of the Faculty of Science at the University of Manitoba. It is located on the south shore of Lake Manitoba. The Field Station property is part of a designated game-bird refuge and wildlife protection area, most of which was designated in 1987 as an ecologically significant area. Established in 1966, the Station is a member of the Organization of Biological Field Stations and the Ecological Monitoring and Assessment Network. It is based at Mallard Lodge, one of the finest lodges on the marsh, that was built in 1932 on the estate of noted athlete and businessman Donald H. Bain.
