Ice Fishing in Idaho: A Complete Beginner's Guide
Everything you need to know to get started ice fishing in Idaho. Best lakes, gear essentials, safety tips, and techniques for catching trout, perch, and kokanee through the ice.
When Idaho's lakes freeze over, the fishing doesn't stop—it just moves onto the ice. From panfish on local reservoirs to trophy lake trout in the panhandle, ice fishing offers a unique winter adventure that's more accessible than you might think.
When Does Ice Fishing Season Start?
Ice fishing in Idaho typically runs from late December through early March, depending on elevation and winter severity. High-elevation lakes (6,000+ feet) freeze earlier and stay frozen longer. Lower elevation reservoirs may have shorter, less reliable ice.
Ice Safety
4 inches: Minimum for walking. 5-7 inches: Safe for snowmobiles and ATVs. 8-12 inches: Safe for small vehicles. Always check ice thickness with a spud bar or auger as you go. Ice is rarely uniform—pressure cracks, springs, and inlet areas can be dangerously thin.

Essential Gear
Cutting the Hole
- Hand auger: Affordable, quiet, lightweight. Works for occasional use.
- Power auger: Gas or electric. Essential if drilling many holes.
- Spud bar: For checking ice thickness and chipping frozen holes.
Fishing Tackle
- Short rod (24-36"): Designed for close-quarters jigging
- Light line (2-6 lb): Clear water and wary fish require finesse
- Jigs: Tungsten jigs in small sizes (1/64 - 1/16 oz) are versatile
- Tip-ups: Passive fishing—set and wait for flags
Comfort & Safety
- Ice shelter: Flip-over or hub-style for wind protection
- Sled: For hauling gear across the ice
- Ice cleats: Traction spikes for slick ice
- Ice picks: Wear around your neck for self-rescue
- Heater: Propane buddy heater for shelter comfort
Techniques That Work
Jigging for Trout
Rainbow and cutthroat trout respond well to active jigging with small spoons and jigs tipped with waxworms or maggots. Fish 1-3 feet off the bottom, varying your cadence until you find what works.
Deadsticking for Kokanee
Kokanee often prefer a still presentation. Set a rod in a holder with a small jig and no jigging motion. They'll often hit when you're not looking.
Tip-Ups for Predators
For larger fish like lake trout or pike (where legal), set tip-ups with live or dead bait suspended at various depths. The flag signals a strike.
Regulations to Know
- Standard fishing license required (no special ice fishing license)
- Limits are the same as open-water seasons for most species
- Some waters have winter-specific regulations—check the IDFG planner
- Shelters must be removed daily unless you're present
Stay Safe Out There
- Never go alone—fish with a buddy
- Tell someone your plans and expected return time
- Carry a charged phone in an inside pocket (cold kills batteries)
- Watch for changing conditions—warm spells can deteriorate ice fast
- If you break through: stay calm, kick hard, roll away from the hole
