The Year Niagara Falls Froze

---

The Niagara River, as is the entire Great Lakes Basin of which the river is an integral part, is a legacy of the last Ice Age.


Niagara Falls indeed has the ability to freeze over. It doesn’t happen so much anymore because of an ice boom. The ice boom keeps the river and the falls from clogging up with ice. This must be done to keep the water intakes for the hydro electric plants running.

In the early 20th centruy it used to become so clogged up that an ice would create bridge. Each year there would be a winter festival held on the ice bridge.

Explanation:

The tremendous volume of water never stops flowing, However, the falling water and mist create ice formations along the banks of the falls and river. This can result in mounds of ice as thick as fifty feet. If the Winter is cold for long enough, the ice will completely stretch across the river and form what is known as the "ice bridge". This ice bridge can extend for several miles down river until it reaches the area known as the lower rapids.

Until 1912,visitors were allowed to actually walk out on the ice bridge and view the Falls from below. February 24th of 1888 the local newspaper reported that at least 20,000 people watched or tobogganed on the ice. Shanties selling liquor, photographs and curiosities abounded. On February 4th 1912 the ice bridge broke up and three tourists lives were lost.


There can also be a great deal of "mini-icebergs" which flow down the Niagara River from frozen Lake Erie. The flow of ice has been reduced considerably by the yearly installation of the "ice-boom" on Lake Erie. The ice-boom is a long floating chain (2miles- 3.2 KM) of steel floats strung across the Niagara River from Buffalo New York to Fort Erie Ontario. It is set in place during the month of December and removed during the month of March or April. It is maintained by the New York State Power Authority. The ice boom helps prevent the ice from clogging the river and most importantly the hydroelectric companies water intakes.

HOWEVER.... The flow of water was stopped completely over both falls on March 29th 1848 due to an ice jam in the upper river for several hours. This is the only known time to have occurred. The Falls did not actually freeze over, but the flow was stopped to the point where people actually walked out and recovered artifacts from the riverbed!
