The Horseshoe Falls, also known as the Canadian Falls, is part of Niagara Falls, on the Niagara River. Approximately 90% of the Niagara River, after diversions for hydropower generation, flows over Horseshoe Falls. The remaining 10% flows over the American Falls. It is located between Terrapin Point on Goat Island in New York State, and Table Rock on the Ontario side of the falls. Much of Horseshoe Falls is located in Ontario, Canada with the remainder in New York State, United States of America.
Boundary controversies 
When the boundary line was determined in 1819 based on the Treaty of Ghent, the northeastern end of the Horseshoe Falls was in New York, United States, flowing around the Terrapin Rocks, which was once connected to Goat Island by a series of bridges. In 1955 the area between the rocks and Goat Island was filled in, creating Terrapin Point. In the early 1980s the United States Army Corps of Engineers filled in more land and built diversion dams and retaining walls to force the water away from Terrapin Point. Altogether 400 feet (120 m) of the Horseshoe Falls was eliminated.
In October 2007, the Horseshoe Falls was featured in a Disney produced video titled Welcome: Portraits of America, made for the United States Department of State and Department of Homeland Security to promote United States tourism. A controversy surrounded the film, because instead of showing just the American falls and Bridal Veil Falls, they focused on Horseshoe Falls, which lies mostly in Canada.
