I always wondered how cold it had to be for Niagara Falls to freeze up. I always wondered how long it took the falls to freeze and at what temperature?

On six reported occasions (1883, 1896, 1904, 1909, 1936 and 1947), the water flow over American Falls has been totally blocked by ice and ceased to fall. But only once has this happened to the much larger Horseshoe Falls (originally known as the Canadian Falls): March 29-31, 1848, the Days Niagara Falls Went Dry.
A strong but slow-moving storm system passing through Lake Erie basin was the most logical suspect in the water flow stoppage. Weather reports indicated that for several days prior to March 29, strong easterly winds drove ice blocks and pack ice back into the open lake waters. Then on the 29th, the winds suddenly reversed direction, coming strongly from the west and southwest, and drove the lake ice rapidly toward the neck of Lake Erie and the Niagara River entrance, somewhere between Fort Erie and Buffalo. The combined force of wind, current and waves jammed the ice blocks together in such a manner that a completely impenetrable ice dam was formed. Thus, waters no longer flowed through the Niagara River toward Lake Ontario and the Niagara Falls.
