An ice sheet will, in theory, grow at a rate of roughly one inch per fifteen FDDs starting from ice between 1/2" and 3" thick (as the ice gets thicker the growth rate decreases as a result of the thermal resistance of the thicker ice).
.
Keeping this in consideration, how fast does lake ice growth?
Now, based on the studies that have been done, once a thin sheet of ice has formed on a lake, it will typically increase at the rate of one inch / 15 freezing degree days (FDDS).
Also, how long does it take for 4 inches of water to freeze? 3 days
Hereof, how long does it take to make an inch of ice?
Based on studies, once a thin layer of ice film forms on a lake, it will add 1 inch of ice for every 15 freezing degree days in a 24 hour period.
How fast does ice melt at 50 degrees?
A 24 hour, 50 degree thaw with winds in the 20-30 mph range can melt a couple inches or more of ice.

How do you tell if ice is thick enough to walk on?
Insert a tape measure into the hole, hook the end onto the edge of the ice, and take the measurement. If your reading is at least four inches, proceed with caution. Ice more than five inches thick will likely hold a snowmobile, and ice more than eight inches thick will likely support a car or small pickup truck.
Is 4 inches of ice safe to fish on?
Use common sense on the ice. If you're going skating or ice fishing with a group, stay off ice that's less than four inches thick. As a general rule, avoid ice that has cracks or ice near inlets or moving water. If you're going ice fishing, may also be a good idea to check with a local expert about ice safety.
