populations and wilderness quality of the Lake Nipigon Basin."

Land Use and Management Options (2001 research document, including maps.)

Key Brook Trout Management Strategies:

  • Restore brook trout populations to 1930s level of abundance and stock structure
  • Manage the brook trout fishery to achieve a success rate of one fish per two hours of fishing effort and one brook trout greater than 55 cm for every eight hours of fishing
  • "Sport fish management practices will be modified to ensure the sustainability and continued world class status of the Nipigon fishery."
  • "The Nipigon River will be managed for a high quality brook trout fishery, with the intent of maximizing the opportunity to catch a memorable sized fish."

The "Nepigon" as it was once spelled, was declared “ the finest trout stream in the world.” (Field & Stream 1887)


Quick facts about the river:

  • Length: 32 miles (51 km)
  • Descent: 313 feet (95 m)
  • Dams: (4) built 1918-1950
  • Flow: 5500 cu. ft/sec before dams
  • Flow: 50% increase after dams

There is enough water in Lake Superior to flood all of North & South America to a depth of one foot.


1. Lake Superior is, by surface area, the world's largest freshwater lake.

2. Lake Superior contains 10% of all the earth's fresh surface water.

3. it takes almost two centuries for the water to be completely replaced.

4. The Lake Superior shoreline, if straightened out, could connect the tip of Florida to the tip of James Bay.

5. In the summer, the sun sets more than 35 minutes later on the western shore of Lake Superior than at its southeastern edge.

6. Some of the world's oldest rocks, about 2.7 billion years of age, can be found on the Ontario shore of Lake Superior yet it was formed during the last ice age only 10,000 years ago.

7. The average annual water temperature of Lake Superior is 40º F. It only very rarely freezes over completely, and then usually just for hours. The complete freezing of Lake Superior occurred in 1962, 1979, 2003 and 2009.

8. There have been about 350 shipwrecks recorded in Lake Superior.

9. There is enough water in Lake Superior to cover all of North and South America with water one foot deep.

10. There are 78 species of fish in the lake.
