Ice first
Those figures are for clear, solid new ice. White or snow ice is about half as strong, so double them. Ice is never the same thickness across a lake: check it with a spud or auger every few steps, stay away from inlets, outlets, springs and pressure ridges, and follow your state agency's advice.
