From this lake, the river flows east to Singer Lake as the current flows northward for . After another segment, the Burntbush River receives the waters of the North Burntbush Lake discharge. Then the river continues towards to the north shore of Burntbush Lake. The latter lake receives the waters of the landfill (from the south) of Soucie and East Soucie lakes. The current crosses Burntbush Lake on its full length, to the southeast. The current flows south-easterly for to the mouth of the Kabika River (Ontario), which drains the waters of the Kabika East River and several streams including Tomlinson Creek. The river then branches to the northeast for, passing south of Mollet Lake (surrounded by marshes), to its mouth where it flows into the Turgeon River.
