Make sure it’s thick
You can tell if the ice is safe and durable if it is transparent. Remember, it should be thicker than a couple of inches. If it’s less, it’s dangerous, and even 2” is cutting it short. Get off that ice if it’s just two inches thick. You want 4 inches to be really safe when fishing.
White ice is weak
It’s hard to evaluate its thickness, and it’s twice as weak as transparent ice. If it’s covered with snow, it’s even weaker, and the snow creates additional pressure that’s going to weaken the ice.
Thaws make ice thinner
If there was warm weather a day or two before, perhaps you should abandon the idea of going ice fishing for a while. A thaw can make the ice thin, especially if it’s powdered with snow.
Ice holes undermine the strength of ice
The more ice holes other people have drilled, the less safe the ice is. If you don’t see any, it doesn’t mean they aren’t there. It’s quite possible for snowstorm to cover them.
Avoid Unmoving Objects protruding from under the ice
Piles, trees, and reeds sticking through the ice make it very dangerous in their immediate vicinity. So are rocks and everything else that protrudes through the ice.
Avoid Moving Water and Narrow Spaces
Ice forming above current is weaker, and the more so the stronger the current. Liquids accelerate in narrows spaces, and that’s why you should also avoid going under bridges, over stream pools, and between islands that are close to each other. Ice is often dangerous in those places even in the middle of winter.
Avoid underwater springs
Basically, it’s a current directed upwards. The water is sometimes warmer than the rest of the water. As you can guess, an underwater spring can melt most of the ice away. It makes the ice incredibly dangerous.
Avoid the mouths of rivers and streams
Ice is often unreliable there, no matter how cold it is outside.
Avoid deep places
You should avoid deep places, and not for the reason one can drown there, no. It just takes a while for ice to form above great depths. Therefore, it is less durable, which means it is dangerous.
Don’t assume it’s safe
Even if you think that every sign is telling you the ice is safe, it doesn’t mean it is. Ice is unpredictable. It can be thicker near the shore. Or thinner. Or non-existent.
Always treat the ice like it’s thin and can break.
Backtrack if on thin ice
Never tread on thin ice that is obviously not strong enough to support your weight and then some. If you hit thin ice accidentally, backtrack with cautious gliding steps, without taking your feet off the ice. Do not proceed forward.
You can tell that the ice is too thin if it’s making creaking sounds without visible cracks.
Backtracking is not always possible
A water body is a dynamic system, even if it’s frozen. If you’ve been on the ice for hours, it can become thinner in places you’ve passed safely, and you’ll have to look for another route.
Also, an ice floe can even break away with you fishing, and that won’t leave you with many options.
Lie down if the ice is about to break
If the ice is suddenly cracking, keep your cool. Be calm, do not panic. Swiftly and gently lie down and crawl to a safer place.
Don’t fish alone
Do not go ice fishing alone. Bring a friend or two. Also, when fishing in a company, don’t stand next to each other and don’t tread ice together. Keep your distance, don’t get closer than 6 feet. It’s also best not to follow each other steps.
Test the ice
When on the move, test the ice with a ski pole. If you can punch through the ice in one go, it’s too weak.
At the same time, testing the ice by kicking it is a terrible idea. Don’t ever do that.
Don’t wear your backpacks over both shoulders when on ice
Carry backpacks and anything you need to carry over a single shoulder. You’ll need to lose that quickly if you break through the ice.
Detach Ski Bindings
When crossing the ice on skis, you should detach the ski bindings and remove the loops of ski poles from the hands. They, too, are something that you need to lose quickly in the event of an emergency.
Ice cleats may be dangerous
Ice cleats are perfect for stopping you from slipping and falling, but then also can damage thin ice.
Use a rope and a pole to cross dangerous places
If you can’t avoid going through a dangerous place (like if you’re evacuating from an icefield about to break off), do it one by one.
Tie yourself with a rope around your waist and bring a long pole with you, holding it across your body. A partner of yours must stand near the loose end of the rope or, better yet, hold it. Once there’s only one person left behind, they should also tie themselves with the rope, and someone who’s already passed through the dangerous spot should hold the other end.
Ice floes turn over
Don’t step on ice floes that have broken off, even for a second. They are not stable and may turn over. It’s way more dangerous than just breaking through the ice.
