Why You Need 5 Inches of Ice for Safe Snowmobiling on Simonton Lake in Elkhart, Indiana

Winter transforms Simonton Lake into a frozen playground, and for many residents and visitors in Elkhart, Indiana, snowmobiling across the ice is one of the most thrilling seasonal activities. However, with great adventure comes great responsibility—and one of the most important safety rules is to ensure the ice is at least 5 inches thick before taking your snowmobile out on the lake.

Ice Thickness and Safety Standards
According to guidelines from the Indiana Department of Natural Resources (DNR) and other outdoor safety experts, 5 inches of clear, solid ice is the minimum recommended thickness to safely support the weight of a snowmobile and its rider. Ice that is thinner than this threshold significantly increases the risk of cracking or breaking under the machine's weight, potentially resulting in a dangerous or even life-threatening situation.
Keep in mind that not all ice forms uniformly. While one area of Simonton Lake may appear solid and safe, another section—particularly near docks, springs, aerators, or flowing water—may be far thinner and less stable.

Understanding Ice Types
Clear, blue or black ice is the strongest and forms when temperatures drop consistently below freezing. On the other hand, white or opaque ice—often the result of snow refreezing—contains air bubbles and is generally much weaker. For snowmobiling, only clear ice at 5 inches or thicker should be considered safe.
Never assume that cloudy, white, or slushy ice can hold a snowmobile, even if it appears thick. It’s also important to avoid pressure ridges or areas where the ice has been recently disturbed, as these zones are prone to weakness.

How to Measure Ice Thickness
Before hitting the throttle, it’s essential to drill test holes and check the ice thickness using a tape measure or ice chisel. Take measurements in multiple spots, especially in the areas you plan to ride. Don’t just rely on reports from others—conditions can change rapidly, and it’s always best to verify for yourself.
For added safety, wear a life jacket or floatation suit, carry ice picks, and never snowmobile alone. Let someone know your plans and expected return time.

Simonton Lake: A Winter Gem Worth Protecting
Simonton Lake is a cherished natural resource in Elkhart County, and the community takes great pride in keeping it safe and enjoyable year-round. Snowmobiling is a fun and exhilarating way to enjoy the lake during the colder months, but safety should always come first.

Following ice thickness guidelines and understanding the risks of thin or uneven ice helps ensure not only your own safety but also the wellbeing of others who share the lake with you. Stay informed, be prepared, and ride responsibly.

Remember: 5 inches is the minimum—more is always better. When in doubt, stay off the ice until it’s safe. Your adventure can wait, but your life is priceless.
