Hayley Gilmartin and her husband, Trevor, were removing an old jacuzzi in their home in Lake Huron, the body of water separating the US and Canada, when they discovered a mysterious, water-filled chamber 20 feet below the surface.
The chamber, which connects to the lake via a six-foot pipe, is believed to be a Prohibition-era tunnel, which likely served as a covert route for smuggling alcohol across the border.
Haley told Newsweek the house 'was all 1970s style,' and they had always planned to remove the jacuzzi that sat in the living room.
The couple said they knew it would be an undertaking to remove, but discovering the 'manhole like thing' underneath the jacuzzi changed everything the couple knew about the house.

'Our house has about three feet of concrete between each floor,' Haley said.
Haley and her husband were not originally thrilled with the discovery as they found it initially unsettling.
'I think anyone finding a man hole under their house in pitch darkness is going to find it spooky,' she said.
'But it's super clear water and nothing crazy has been found in the water.'
After mustering enough courage to see if it was safe to venture down the man hole, the couple discovered an entire other room.
'We scuba-dived in the river and found the other end of it, which is a huge tunnel,' Haley said.
She also explained how it is 'impossible' to pump the water out of the mystery room because it 'is still getting water from Lake Huron and the rivers that it is connected to.'
@hayleyg099 Took out the Jacuzzi in the house we purchased 4 years ago and found a manhole to a room that goes 20ft under the house. Of course Trevor wanted to get in and swim around. Ended up finding another passage with a bolted wooden wall infront if it. To be continued when the water gets warmer #creepy #mystery #houseproject #hiddenroom #gopro #history #secret

As the couple plunged head first into the history of the house and the reason behind the room, they were bombarded with a number of theories as to what the room is actually meant for.
'We were told by people in the area that our house used to load brine onto freighters during the Second World War but not sure how accurate that is,' Hayley told Newsweek.
'The wildest theory we've heard is that it was used in the prohibition days to smuggle alcohol over from Canada since it's so close. Although we do find many prohibition era bottles in our area.'
They also learned from several neighbors that they also have tunnels that lead to secret rooms of sorts beneath their homes.

@hayleyg099 Update! Part2!! Since everyone knows our house, we thought we would share what we do know! This is not a septic and not a basem*nt. This room is still getting water from Lake Huron/the river, that it is connected to.( thus why its impossible to pump the water out) We tore out the jaccuzi because it was broke and way too much to fix since it was from the 70s. Nothing drains into this room from our house. We do know that our house was a pumping station back in the day. We haven’t tore down the wooden wall, but that is next! The last part of the video is of the pipe in the lake that is connecting to the room under our house which is supplying it fresh water. We definetly will keep updating and hope to find out more and seal it off, if possible! For those who dont know how big the Great Lakes are… they are huge, surrounding all of MI, and are fresh water. The room water temp is about 52degrees which is a couple degrees warmer than Lake Huron. @TrevorHayley G #update #mystery #hiddenroom #jacuzzi #part2 #creepy

During Prohibition, Lake Huron and the St. Clair River transformed into bustling smuggling routes where those opposed to the US temperance movement transported bootleg alcohol from up north across the border.
Historian Douglas Bancroft said the area was the reason for 75% of illegal exports during Prohibition, he told The Times Herald.
Hayley and Trevor also found a boarded-up wooden door in the room, which they have yet to remove but plan on doing so in the future.
"We are going to keep exploring it and if possible we will drain it and maybe create a game room or bowling alley lane down there," Hayley told Newsweek.
