The river begins at an unnamed lake in
geographic Somerville Township in Minden Hills, about south of the community of Buller, and flows south to
Corben Lake where it passes into geographic Somerville Township, Kawartha Lakes. It exits Corben lake at its southern tip, continues south, passes under
Kawartha Lakes Road 45, and reaches
Four Mile Lake, leaving that lake at the south. It turns southwest, flows under
Ontario Highway 35, and reaches its mouth at the northeast side of Balsam Lake, about north of the community of
Rosedale. ==References==
