Late-winter reality on the Chain: what to expect and how to think like a local
Late winter on the Fox Chain of Lakes is a transition, not a constant. Even if you drove across Fox Lake two days ago, conditions can change fast when temperatures swing, wind scours snow off the ice, or a warm afternoon weakens the surface. Around Big McDonald and Little McDonald you’ll notice the same patterns: bays that get afternoon sun thin first, channels between lakes and spots downstream from the boat launches stay slushy longer, and shallow, weed-filled flats can carry white ice that looks solid but hides water under the surface. Snow cover makes things trickier — it insulates and delays freeze-up, and it hides cracks and pressure ridges.
Think in terms of variability, not "good" or "bad" ice. Walk out with a plan: pick a route you can repeat back to shore, check ice every few dozen feet with a spud or chisel, and watch for visual cues — darker patches, slushy seams, and open water. If you see water near the north end of the lake or near the channel between Fox and McDonald, treat the area as suspect. Locals also watch weather patterns: several days of sun or a sudden thaw followed by cold nights creates honeycombed ice that can be deceptive. Before heading out, talk with neighbors or folks at the landing who were on the ice that morning and, if in doubt, stay closer to shore until you can verify thickness for yourself.
How to check ice safely and what thickness really means
Start with basics: ice thickness is only one part of safety. Use a drill or ice auger, an ice chisel (spud), or an extendable tap stick to check frequently — every 10–15 feet if you’re walking, more often if conditions shift. Clear ice is stronger than white (porous or snow) ice. When measuring, clear a small hole so you can see the ice layers and note whether there’s slush or water on top. Keep measurements conservative: 4 inches is commonly given for standing and fishing, 5–7 inches for snowmobiles, and more for vehicles, but local conditions can override those numbers. Always assume variability and re-check even after measuring a solid patch.
Watch for specific hazards around the Chain: boat channels, inlets/outlets, spring-fed spots, and the mouths of creeks often have current or slightly warmer water that weakens ice. Look for pressure ridges and cracks forming near shorelines; those are signs the lake is flexing and ice is no longer uniformly strong. If you hear hollow or brittle sounds underfoot, move back to known solid ground. Use a buddy system and keep distance between people and vehicles to spread the load. If you find thin ice unexpectedly, leave the route and return the way you came — ice that supported you forward is more likely to support you backward.
Gear, clothing, and simple habits that save lives
Dress for immersion rather than just cold: layers, a waterproof outer shell, and avoid heavy boots that fill with water if you break through. A personal flotation device or float suit is the most important piece of gear — wear it anytime you’re beyond ankle-deep shore ice. Carry ice picks or screw-style ice claws around your neck; they’re simple and give you the purchase needed to pull yourself up if you fall through. Add a length of 3/8" polypropylene rope (50–100 feet) with a buoyant throw bag, a whistle, and a lightweight ladder or foldable rescue device in your vehicle or sled during outings.
Other practical habits: keep your phone in a waterproof case, but don’t rely on it alone — batteries die in cold. Carry a spud bar and a tape measure; mark your route with stick flags or GPS waypoints and use them on the return. When traveling with others, space out vehicles and sleds by at least 50–100 feet and stagger positions to reduce load concentration. If you’re heading to popular holes on Big McDonald or Fox Lake, check in with the folks at the landing: they’ll often share current safe routes and where to expect slush or flow. Small preparations make the difference between an uncomfortable day and a real emergency.
If someone falls through and how to plan an exit route
Keep your head and keep others from crowding the edge. From shore, call 911 immediately and throw flotation — a rope, a life ring, or an anchored branch — aiming for the person, not directly at their head. Lie flat and distribute your weight by sliding a ladder, door, or board out across the ice to reach further without concentrating weight. If you’re the one in the water, fight the instinct to stand: control your breathing, bring your legs up so you’re horizontal, kick to get onto the ice while using ice picks or hands to pull forward. Once you’re out, roll or crawl away from the hole to reduce pressure until you reach thicker ice, then move to shelter and warm fluids as soon as possible.
Plan your exit before you go out: know the closest ramp or road access on Fox Lake or the McDonald basins, and park so you can reach it quickly. Share your plan and expected return time with someone on shore, and avoid going alone on marginal days. Rescue gear should be accessible on every trip, and practicing basic toss-and-reach drills with friends can speed action when seconds count.
