Key takeaways

  • North Dakota Game and Fish says to stay off ice 2 inches thick or less, and to have at least 4 inches of good ice to walk on.
  • Snow on ice can hide thin spots, cracks and open water. Check the ice with a chisel or test holes as you go.
  • If you fall through, turn back the way you came, use ice picks to pull out, and roll away from the hole.
  • Youth ages 12 to 15 must take the free Boat North Dakota course to drive a boat or personal watercraft of 10 horsepower or more alone.

For much of the year, North Dakota's water is frozen, and the biggest risk is going onto ice that is too thin. Check the ice yourself, as often as you can, every time. North Dakota Game and Fish says you take a risk any time you go onto the ice, because thickness is never the same everywhere. In summer, wear a life jacket on every boat and paddleboard.

North Dakota drowning and boating numbers

1.17 per 100,000

North Dakota's average yearly drowning death rate, 2018-2021, age-adjusted (CDC). The U.S. rate was 1.31.Source: cdc.gov (opens in a new tab)

CDC counts drowning deaths of residents; the Coast Guard counts boating incidents, not deaths through the ice. See our North Dakota data page.

Ice safety

North Dakota Game and Fish's general rule of thumb for good ice:

Ice thickness Guideline
2 inches Stay off (opens in a new tab)
4 inches A person walking
6 inches A snowmobile or ATV
8-12 inches A car or small pickup
12-15 inches A medium pickup truck

The department's other ice warnings:

  • Thickness varies. Look for clear blue ice. New ice is stronger than old ice. Drill test holes or use an ice chisel as you move out.
  • Snow hides danger. Snow acts much like a blanket, insulating thin ice (opens in a new tab), and it can hide cracks, weak ice and open water.
  • Objects weaken ice. Be careful near partly submerged trees, brush, embankments and structures. Ice forms more slowly in shallow water and where objects soak up sunlight.
  • Temperature swings make ice expand and contract, creating cracks and pressure ridges.
  • Vehicles: driving on ice early or late in the season is an "accident waiting to happen." Don't drive on ice at night or when it is snowing.

Carry an ice chisel and a pair of ice picks. See ice thickness safety.

If you fall through

Game and Fish's self-rescue steps:

  • Turn toward the direction you came (opens in a new tab). The last place you stepped is the strongest ice.
  • Put your hands and arms on the unbroken ice, kick your feet, and use your ice picks to pull yourself up.
  • Once you're on the ice, roll away from the hole. Don't stand up.

If someone else falls in, keep calm and don't run out to them. You can go from rescuer to victim in a second. Reach them with a pole, board, rope or blanket, or throw a life jacket or an empty jug. Call 911. People who have been in cold water may seem fine at first but still need medical care. Read falling through ice and hypothermia after cold water.
