Great Lakes trivia thread

Well, it was but I doubt it now. Due to diverting almost all the rivers that used to run into it for irrigation the actual "water surface" is way down from what it was.

I think you might be confusing the Caspian Sea with the Aral Sea.

Anyone care to guess what Lake Bernard's claim to fame is?
Near Parry Sound Ontario, it is the largest freshwater lake in the world - without this!

I don't think Champlain was the first European to see all of the great lakes, just the eastern part.

Jean Nicolet is widely claimed to be the first European to see Lake Michigan.

Sea lamprey's entered the great lakes via the man made locks and decimated the large predator species such as lake trout.
Alewives, a small fish, also entered the great lakes the same way. Their population exploded when the lake trout died off.
So, the government brought in pacific salmon to eat the alewives.
Then the salmon at them and the perch, too.
So now there's a huge imbalance of native species VS non-native species, directly caused by the opening of the St. Lawrence Seaway.
At least 25 non-native species now inhabit the great lakes.

I will have to check out the 1st european bit, thanks Moss.

Re lampreys, the first sea lamprey seen in Lake Ontario was in 1835. The lamprey is not an eel, but the American eel population has declined radically in the lakes while the lamprey has thrived.

One Sturgeon in Lake Michigan was found to have 18 lampreys attached to it.

The lamprey population was stable in Lake Ontario until the Welland canal was deepened in 1921.

Lake trout commercial catches were wiped out by the lamprey as follows:
Lake Huron Lake Trout catch 1937 1.5 million kilograms. 1947 was zero.
Lake Superior catch was 2 million kilograms in the late 1940s. In 1961, when Lampreys arrived, the catch was 167 kilograms.

Lamprey populations increased between 20x and 50x per year through the 40s and 50s.
A chemical called TFM was added to lake water in 1962 and by 1966 the lamprey population had been reduced by 95%.
Their numbers have climbed again to almost "high" levels.

Biggest freshwater lake without any island. *I have a pal with a cottage on that lake.

Hey Moss, the book I have says there are 185 nonindigenous species now. That includes things like plants and even the septicemia virus. ( I know I'm a nerd but I love this crap).

On a lighter note. This is how I was taught to remember the names of the Great Lakes-I think around the fourth grade level. "HOMES" H-Huron, O-Ontario, M-Michigan, E-Erie, S-Superior. Just a thought?

Yupper, HOMES was how we learned too.

Thanks to my parents taking us camping/tenting each summer, I learned their names by fourth grade by swimming in most of them .... I also learned what 'turning blue' means one hot sweaty summer day, following my older brother, diving into Lake Superior off a huge rock....
