Luvevolution Posted May 21, 2010 Report Share Posted May 21, 2010 here's a good link http://www.niagaraparks.com/media/geology-facts-figures.html it says that it was 1-1.5 metres per year, but now it's about 1 foot per year in errosion. with the new tunnel, it's probably gonna be as low as 1 foot every 10 years. . great reading though, if it interests you.

hawk-eye Posted May 22, 2010 Report Share Posted May 22, 2010 Question 2 - What is the longest migration within the great lakes of an individual fish? I read an artical in Outdoor Canada a few years ago that talk about one fish. This was a Steelhead that was tagged and released in lake Michigan arround the Green Bay area and was caught in the Bay of Quinte 6 months later. Dont think this is a migration more likley raised fish that didnt know where to go. Link to comment Share on other sites More sharing options...
