2. The Niagara Falls public library has this information:
尼亞加拉大瀑布的公共圖書館有這樣的信息:
From June to November 1969 the American Falls were dewatered. This
action cut back the normal flow of 60,000 gallons a second to almost
nothing. Most of the diverted water was either sent over the Horseshoe
Falls or diverted to the Robert Moses generating plant's upriver intakes.
從1969年6月至11月,美國瀑布減水。這一行動削減了每秒60,000加侖,
幾乎沒有水流動。大部分改道的水,送到馬蹄瀑布以及上游進水口的羅伯
特摩西發電廠。
The action enabled Canadian and US power companies and the US
Army Corps of Engineers to do on-the-spot inspections and aerial
photographs of the river bed's rock formation. This was all part of a plan
to reduce erosion to the Falls.
這行動可使加拿大、美國的電力公司和美國陸軍工兵部隊,做現場檢查河
床和岩石形成的航拍照片。這是所有計劃的一部分,以減少瀑布的侵蝕。

can be seen in the upper right.
1969年瀑布變得安靜,尼亞加拉河臨時改道。可以看到在右上角的攔水壩。

base of the falls.
水被轉道,可以看到瀑布基底大量倒塌的岩石。
7. The falls as they normally run, as seen in June, 2009. A natural
phenomenon, Niagara Falls sees between four and six millions cubic feet of
water go over its crest every minute. The Falls are 188 feet high, with the
deepest section of the Niagara River just at their base-going down 170 feet.
