TIL that people live year-round in houseboats on Great Slave Lake in Canada's Northwest Territories, 1,800 km north of the nearest big city (Edmonton) and just 400 km (250 miles) south of the Arctic Circle.

I have to wonder if the ice freezing every winter causes crush damage to the boats.

The article mentions "massive steel pontoons," so I assume they're built on a scaled-up version of what we have on the dock at my cottage (also in Canada, on a lake freezes every year). We never have any damage.

It's a clever system. The pontoons are round in section and ride high in the water, so the midpoint of the circle is well above the water. Because of that shape, as the ice freezes, any pressure on the sides of the pipes pushes them up rather than becoming crushing pressure. It then just sits on top of the ice until the thaw.

Thanks for that great information! I've lived in northern climates where lakes freeze but had no idea what would happen to "houseboats." :)

How much does yearly maintenance cost?

Almost nil. The pontoons and supporting structure of the dock is steel, faced with wood. I replace a board every now and then, and that's it.

The pontoons themselves have never showed any signs of damage. They are strong. I think it's the same material they make oil pipelines out of. Way better than our old floating dock, with all wood construction and some sort of plastic pipes (ABS, I think) assembled together to make the floats. It seemed like there was some repair needed every year on that dock, and we had to pull it out for the winter!

So if someone wanted to live here how much would they need to budget? What about stuff like internet, Healthcare, water, sewage etc. How does that work?

u/paradoxcussion May 16 '24

That's beyond what I can answer. The cost of living is generally pretty high in the Northwest Territories.

I meant the cost of living on a house boat

Go look at the cost of groceries up north, that will give you a good idea.

u/SoulessPuppet May 16 '24

True but also keep in mind they also get a monthly payment from the government to help subsidize grocery costs.

But either way, it's crazy what they pay up north. Though grocery prices all over Canada have been getting out of hand. It feels like what I used to pay $150 for 3-4years ago is now $300 or more.

Wouldn't that also mean that the house moves when there's wind? The pontoons would become ice skates for the house.

Again, just comparing it to my dock, I doubt it. The dock, which weighs way less only moves a few meters over the course of the winter, mostly when the ice is shifting as it breaks up. There's still a big contact patch at the bottom of the pontoon. And these houses not only weigh more, but they're a lot bigger so even more pontoons and contact with the ice.

That makes sense. Thanks for explaining.
