While it is doubtful the lake will face as drastic changes as it did during the Pleistocene Epoch, it is in fact likely that Niagara Falls will, in time, migrate up stream causing it to converge with Lake Erie waters. However by the time that takes place, the basin of Lake Erie will have lowered significantly.
The falls could be replaced by a series of rapids. 50,000 years from now, at the present rate of erosion, the remaining 20 miles to Lake Erie will have been undermined. There won't be a falls anymore, but there will still be a river at work.
Currents in Lake Erie can be dangerous! Any current flowing faster than 2 mph is considered dangerous. Dangerous currents can exceed 5 mph — faster than an Olympic swimmer can swim.
