Tis’ The Season
Winter time = Winter play Snow Machining Ice fishing Snow shoeing Skiing You never know when you will have to
encounter and cross large bodies of ice
When is ice safe?
There is no concrete answer. You can’t just look at the ice and
determine if it is safe.Multiple factors are involved to determine if
the ice is going to support you.(age, thickness, temperature)- plus the depth of water under the ice, size of the water body, currents, the distribution of the load on the ice.
Guidelines
• 5-6” of clear ice is recommended for foot traffic.
• 12”of clear ice is recommended for vehicles.
Watch out for overflow
Overflow is layers of slush, water, and ice
They are sometimes
hidden under snow,
and may suddenly
give way.
Extra pairs of dry socks and boots come in
handy if overflow is encountered.
Did you know?
Ice is strongest where it’s clear, and weakest where it’s cloudy or full of large bubbles.
Snow cover insulates ice, making it thinner.
On smaller or mid-sized lakes, ice is usually consistently thick.
Driving on Ice
When driving on the ice, keep it slow, under 10 mph.
Ice waves can be created when you drive to fast and can cause ice to break ahead.
If you’re with a group of vehicles on the ice, keep a good distance between vehicles to
spread out the weight.
Driving on Ice
Keep vehicle windows open. You may want to have flotation available, such as a seat cushions.
It is not recommended to wear life jackets inside vehicles that are traveling on the ice.
Did you know? Fresh water ice can support heavier
loads than sea ice. Sudden drop in air and ice
temperatures will cause an ice sheet to contract creating cracks
Wind can affect the position of ice sheets
What to do if you fall through the ice
Stay calm. Do not attempt to swim, swimming will cause your body to lose heat much faster than if you stay as still as possible.
Use a whistle to attract help. Act slowly and deliberately to conserve heat and move slowly back
to where you entered the water. Expect a decrease in your strength and ability to move.
Make the moves to attempt to get out at the beginning, while you can.
If you are wearing a snowmobile helmet and your face is in the water, remove the helmet as quickly as possible, because it can fill with water and cause you to drown. Hold onto it to stay afloat.
Once on the ice, try to push yourself forward on your stomach or roll on your side to keep the weight distributed over a greater surface area. Do not stand up until you have moved onto the ground or an area of solid ice.
Remember, you take a risk anytime you go out onto the ice.
Carry hand-held ice spikes. They are likelarge nails, on a line that can be threaded through a jacket.
Be Prepared
Proper winter gear Ice cleats Ice picks Shovels Water proof backpack with spare wool
socks and emergency kit. Have a plan – Where you are going who
you are with and when you will be back. Buddy system, never go out alone!
Keep your pets leashed
Your pets can wonder off on ice and fall though weak spots.
Never dive in to rescue your animal, get help.
By keeping them leashed or tied up you prevent any tragic accidents from happening.
