Recession for at least the last years has been estimated at 1 to 1. Its current rate of erosion is estimated at 1 foot per year and could possibly be reduced to 1 foot per 10 years.
The current rate of recession is unclear; assessing its value remains the responsibility of the International Joint Commission.
The International Boundary Waters Treaty stipulates the minimum amount of flow over the falls during daytime, nighttime and the tourist season. Erosive forces include the action of frost from the spray, the dissolving action of the spray itself, and abrasion action of the softer shales by fallen limestone boulders.
No one knows when the next major rock fall will occur in the Horseshoe Falls; the effect could be to speed up erosion. A stable position is abandoned when the crest line develops a notch configuration and the Falls retreats relatively rapidly until a new stable position is attained.
The Cascade Rapids above the falls are about 15 metres 50 ft. Climate change is also an influencing factor on the future of the Niagara River as an integral part of the Great Lakes Basin; models indicate a drying up of the Basin.
Isostatic rebound continues to affect the Great Lakes Basin and consequently the flow of water through the Niagara River. All things considered, scientists speculate that perhaps 2, years from now the American Falls could dry up.
It is a stationary feature collapsing by rock falls and landslides, carrying less than seven percent of flow before diversion; this bit of water is shallow and spread out, therefore ineffective as a major erosive power.
As a dry falls, it could appear like the Niagara Glen does today. The falls could be replaced by a series of rapids. Close and continue browsing. Niagara Parks is committed to protecting the health and safety of all guests and staff.
