Lac Seul provides some of the finest trophy Northern Pike and Walleye and also provides access to the vast, practically untouched wilderness surrounding it.
The numerous islands on Lac Seul are considered regionally significant calving habitat for the rare boreal woodland caribou.
The natural capacity of Lac Seul is augmented by the diversion of water from the Albany River drainage basin at Lake St. Joseph, allowing hydroelectric stations at Ear Falls where the English River leaves the lake, and Manitou Falls, 30 km downstream, to generate 90600 kW of electricity.
The community of Hudson, Ontario, served as a key transportation hub due to its position along the railway line.
From Hudson, supplies were transported via steamboats, scows, and tugboats across Lac Seul toward Red Lake, supporting the burgeoning mining industry in the region.
