The Delta Waterfowl Research Station was established in 1938 east of Delta Beach to carry out waterfowl research. In 1966, the University of Manitoba leased lands at the west end of the marsh from the Province of Manitoba and developed the Delta Marsh Field Station (University of Manitoba) as a teaching and research centre. The field station closed in 2011 after massive flooding of Lake Manitoba caused some damage to the buildings. The Delta Waterfowl Foundation is an international research and conservation organization inspired by and named for Delta Marsh. Delta Marsh is listed as a Wetland of International Importance under the Ramsar Convention.
