Just for fun, we’ve put together some facts about the 5 Great Lakes! Some information you may know, and some you may not. We will be sharing this in each newsletter. First is Lake Superior!

  1. Lake Superior is actually not a lake at all, but an inland sea.

  2. All of the four other Great Lakes, plus three more the size of Lake Erie, would fit inside of Lake Superior .

  3. Isle Royale is a massive island surrounded by Lake Superior. Within this island are several smaller lakes. Yes, that’s a lake on a lake.

  4. Despite its massive size, Lake Superior is an extremely young formation by Earth’s standards (only 10,000 years old).

  5. There is enough water in Lake Superior to submerge all of North and South America in 1 foot of water.

  6. Lake Superior contains 3 quadrillion gallons of water (3,000,000,000,000,000). All five of the Great Lakes combined contain 6 quadrillion gallons.

  7. Contained within Lake Superior is a whopping 10% of the world’s fresh surface water.

  8. It’s estimated there are about 100 million lake trout in Lake Superior. That’s nearly one-fifth of the human population of North America!
