In normal conditions the lake surface area covers 230 hectares to an average depth of 2.5 metres. It is the terminus for water flowing from the Richardson River via Souths Creek and three smaller reservoirs to its southwest.
The lake was constructed in 1961 as an irrigation reservoir for dairying and for cereal crops. Water was diverted from the Richardson River during high-flow periods to create a reservoir holding an average of 1,130 ML and a maximum of 2,250 ML. More recently,[timeframe?] the lake has been used for waterskiing and other recreational and tourist activities based in the nearby town of Donald and St. Arnaud.
Native flora include species common to grassy wetlands. The shoreline is dominated by River Red Gum (Eucalyptus camaldulensis) associated with Canegrass (Eragrostis infecunda) Tangled Lignum (Muehlenbeckia florulenta) and spiny sedge (Cyperus gymnocaulus). The southern and southwestern shore is also home to stands of Black Box (Eucalyptus largiflorens)
Three threatened species are present: the Pale Spike sedge (Eleocharis pallens), Chariot Wheels (Maireana cheeli) and Turnip Copperbur (Sclerolaena napiformis). Upstream land clearing in the 1960s has increased salinity levels in the lake, but a 2006 water quality study indicated sufficient fresh water to maintain existing vegetation.
