A new post was established in 1884 at Mammamattawa, Ontario at the confluence of the Kenogami River and the Kabinakagami River. It was known as the English River Post, as the Kenogami was also known as the English River. Long Lake diversion project In 1937-38, the Hydro-Electric Power Commission of Ontario, now Ontario Power Generation, built the Kenogami Lake Dam () and Long Lake Diversion Dam to divert this river's headwaters to empty through Long Lake and the Aguasabon River into Lake Superior. The former backed up the headwaters, while the latter controlled the outflow into the Aguasabon River. The diversion has shifted an average flow of per second from a drainage basin of almost from James Bay to the Great Lakes Basin. Initially, the diversion supported forestry development and hydroelectric development further downstream on the Great Lakes at Niagara Falls; no hydroelectric development on the watercourses on the diversion project was practical initially. A further stage was completed in 1948 when the Hayes Lake Dam (for water control) and Aguasabon Generating Station (for hydroelectricity), the former just upstream of the latter and the latter just upstream of the mouth of the Aguasabon River at Lake Superior, to support a pulp and paper mill at the adjacent town of Terrace Bay.
