* northwesterly to a south discharge;
* northerly and westerly to its mouth on the south shore of Puticamica Lake (length: ) that the current flows westward on ;
* northerly to the south shore of Lake Waswanipi that the current flows through on then merge to the current of Waswanipi River.

Toponymy

The natives used the name "Pusticamica" to designate this watercourse.

At the request of the Commission de toponymie du Canada, the name "Rivière O'Sullivan" has been attributed to evoke the work of life of Henry O'Sullivan ( Sainte-Catherine-de-Fossambault], 1845 - Loretteville, 1912). After studying at Laval University in 1869, O'Sullivan worked as a land surveyor, geologist and explorer in the Department of Lands and Forests. O'Sullivan explored much of Labrador, Gaspésie, all of Nord-du-Québec .

The toponym ''O'Sullivan River'' was formalized on December 5, 1968, at the Bank of Place Names of the Commission de toponymie du Québec.qc.ca/ct/ToposWeb/fiche.aspx?no_seq=45937 Commission de toponymie du Quebec - Bank of Place Names - Toponym: "O'Sullivan River"
