Ice - Safe Load vs. Thickness
Safe loads vs. thickness for clear and solid ice. This calculator helps determine the safe load capacity based on ice thickness, considering factors like ice age, distance to shore, and water conditions.
Ice Safety Reference Guide
Safe loads for clear solid ice are indicated in the table below. This is a general guide only - KEEP OFF the ice if you are not absolutely sure of its safety.
Factors Affecting Ice Strength
- Age: Newer black ice is stronger than old milky ice
- Distance to shore: Ice close to shore is weaker than ice farther out
- River outlets and inlets: Ice near outlets and inlets is weaker
- Obstructions: Rocks, trees, and plants weaken ice
- Water currents: Flowing water weakens ice structure
- Snow cover: Affects insulation and ice formation
