People have been studying Niagara erosion since the mid 1800’s.
From 1842 to 1905, the average rate of erosion of the Canadian Horseshoe Falls was 1.16 metres (3.8 feet) per year.
When water in 1906 was diverted to feed Niagara Power plants the erosion dropped to .70 metres (2.3 feet) per year until 1927.
With even more diversion today and anti-erosion remedial steps diversion is much less than one foot per year. The predicted future erosion is approximately 1 foot very 10 years.
I have to bite my lip when I’m near the edge of the Canadian Horseshoe Falls in Queen Victoria Park and hear guides tell their groups erosion is up to 3 feet per year.
I’ve been hanging around this area for 50 years and at that rate the falls would have receded about 150 feet. The parapet (stone wall) at this area would have had to be moved several times. It hasn’t been necessary. It just ain’t so folks.
