Named after the buffaloberry, it is a medium-sized saline lake within an area characterized by mostly fresh water aquatic environments.

It is also an Important Bird Area (IBA) of Canada and its northern most island is the location of the provincial Redberry Wildlife Refuge (52°42′00″N 107°12′02″W / 52.7001°N 107.2006°W / 52.7001; -107.2006).

In 1940–41 with the salt content at only 15g/L, Donald Rawson[7] from the University of Saskatchewan's biology department stocked Redberry Lake with whitefish (Coregonus clupeaformis).

The lake and its islands are important nesting areas for birds such as American white pelicans, piping plovers, and whooping cranes.
