Site description The Sand Reef Islands of Lake Manitoba are located to the east of Ducharme Island, and to the west of Duck Island (also known as Big Birch Island). The IBA additionally includes those islands that are roughly midway between the Sand Reef Islands and Mathews Point. Alonsa is the closest major town, located to the southwest, but the hamlet of Vogar, to the northeast, is nearer to this site. The islands are extremely low-lying with a limited amount of relief and consequently they are subjected to flooding during periods of high water and heavy winds.
