The lake is known to have excellent examples of prehistoric amber fossil of cretaceous age.[1] This type of amber is called as "Chemawinit", according to an Indian tribe which lives in this area.[citation needed] Another name of this amber is "Cedarit".[2] This amber contains many organic inclusions. To date, these inclusions have not been thoroughly researched.[3]
The lake's main source is the Saskatchewan River, which forms a delta on the northwest side of the lake. The flow of the Saskatchewan River to Lake Winnipeg on the eastern end of Cedar Lake is regulated by the Grand Rapids Dam built in 1962 by Manitoba Hydro.[4][5][6]
