Things could soon change at the Falls after the New York State Parks Department released a proposal to "turn off" the American and Bridal Falls - two of the three waterfalls that make up the spectacular natural feature.
The plan calls for water to be temporarily diverted towards the Horseshoe Falls on the Canadian side of the border, while work is being done to replace the bridges and construct new piers.
Taken by urban explorer and photographer Johnny Joo, 25, the images document the decline of the city of Niagara Falls, New York.
Pictured are abandoned factories and hospitals - as well as the interiors of the once-thriving Hotel Niagara where Hollywood icon Marilyn Monroe once stared in the movie ‘Niagara'.
Johnny, from Ohio in the heart of the US 'Rust Belt’, said: “Sadly, this once wonderful piece of America’s great collection of family friendly tourism has turned away from happier days, while much falls into a state of disrepair, becoming further and further forgotten beneath crumbling rooftops, flooded hallways and the passing of time.”
The Canadian side of the world’s most famous waterfalls continue to attract millions of visitors every year, but the American city that bears the same name has a problem.
A 2000 census put the population at 55,510 but only a decade later the number of residents had fallen to only 50,193.
The most recent census was taken in 2013, where the population had fallen even further to 49,468.
Other pictures show abandoned rooms littered with rusted remains of bed frames and old equipment and covered in inches of water in most areas, many floors frozen as icicles hang from the ceilings and bed railings.
Johnny added: “Most of Niagara on the US side now sits a dreary mess, while preservation societies push for revitalisation of specific buildings with little to no positive reaction from the city.
"A collection of structures all sit gathering dust as people continue to pass by paying little mind to what has been left behind.
“Though these images show the abandoned and forgotten, the US side of the falls is still a very beautiful place, with much to see and a peaceful, calming atmosphere to it.
"Some also argue that it is the best view of the falls.”
