Ice On and Ice Off Dates for White Iron Lake

Ice on and off dates for White Iron Lake

The following table shows the dates that ice covered the entire lake and the dates the lake is completely free of ice.  We don’t have ice on dates for 2017, 2016, or 2012.  If you have this information, please let us know.

*White Iron iced over on November 23 but opened up and froze again on November 30. 

The following information is from the MN DNR web site at https://www.dnr.state.mn.us/safety/ice/index.html

Ice is Never 100% Safe!

Ice in dates should not be used to track ice thickness for recreational use. Ice conditions can change rapidly and should be checked frequently. 

When is ice safe?

There really is no sure answer. You can't judge the strength of ice just by its appearance, age, thickness, temperature, or whether or not the ice is covered with snow. Strength is based on all these factors -- plus the depth of water under the ice, size of the water body, water chemistry and currents, the distribution of the load on the ice, and local climatic conditions.

There is no such thing as 100 percent safe ice.  Your safety is your responsibility. Check ice thickness at least every 150 feet.

Did you know?

New ice is usually stronger than old ice. Four inches of clear, newly-formed ice may support one person on foot, while a foot or more of old, partially-thawed ice may not.

Ice seldom freezes uniformly. It may be a foot thick in one location and only an inch or two just a few feet away.

Ice formed over flowing water and currents is often dangerous. This is especially true near streams, bridges and culverts. Also, the ice on outside river bends is usually weaker due to the undermining effects of the faster current.

The insulating effect of snow slows down the freezing process. The extra weight also reduces how much weight the ice sheet can support. Also, ice near shore can be weaker than ice that is farther out.

Booming and cracking ice isn't necessarily dangerous. It only means that the ice is expanding and contracting as the temperature changes.

Schools of fish or flocks of waterfowl can also adversely affect the relative safety of ice. The movement of fish can bring warm water up from the bottom of the lake. In the past, this has opened holes in the ice causing snowmobiles and cars to break through.

For more information on ice safety contact the MN DNR and ask for our free ice safety publications, which include the brochures, "Danger, Thin Ice" and "Cold Water Kills" and the wallet-sized reference card and 11X14 posters titled, "Minimum Recommended Ice Thicknesses."
