Ice Fishing in Idaho
Ice fishing is generally a safe activity if you pay attention to ice conditions and remember that they can change from day to day.
The best way to check ice thickness is to drill a test hole before venturing too far, follow these guidelines, and remember, it’s ultimately your responsibility to determine if it’s safe to be on the ice.
General guidelines for ice safety are:
- Three to four inches of solid ice is the minimum to support a person, and thicker ice is needed for groups.
- 10 inches of solid ice are needed to support an ATV or snow machine.
- Ice does not typically get thick enough to drive cars and trucks on Idaho's lakes and reservoirs.
- Drill test holes to determine thickness, and remember thickness is not always uniform. Holes can be no larger than 10-inches in diameter for safety sake.
- Beware of conditions that can create weak ice, such as inlets and outlets, springs, or near docks and other structures tha can absorb sunlight and weaken ice.

What you need for ice fishing.
- An ice auger to drill holes. A manual auger is relatively inexpensive and can be bought for under $100. You can also buy a gas-powered auger, or an auger that attaches to a cordless drill.
- A slotted ladle will keep your fishing holes free of ice.
- A short jigging rod and/or ice-fishing tip-up rigs are handy, but you can also use a standard-sized rod. Because you can fish up to five rods, a combination of rods and tip-ups increase your odds of catching fish.
Targets, tackle and techniques
The two most common fish caught are trout and perch, but you might also catch bluegill, crappie, kokanee, and even bass. Considering you’re catching the same fish ice fishing that you would catch other times of year, you’d think fishing techniques would be the same, but ice fishing is a little different.
Here area some tips for ice fishing:
- Try different depths to find fish. Generally speaking, perch like deeper water (10 to 40 feet) and are close to the bottom. Trout will often be found throughout the water column, and may be caught cruising within in a few feet of the ice.
- One way to measure the depth you’re fishing is to drop your bait to the bottom and count the revolutions of your reel handle as you reel your bait off the bottom. When you figure out where the fish are biting, you can return to that depth.
- Jigging is effective. To jig, slowly bring the rig up about one foot then allow it to settle back down, and repeat. The movement of the bait attracts a fish’s attention. Some anglers prefer to just set the line and watch for a strike.
- Perch, bluegill and crappie can be delicate biters and small hooks, small bobbers and a light touch are often needed to hook fish.
- As a general guideline, trout are cruisers, but perch don’t move a lot. If you’re after perch, move around until you find them. Sometimes trout will find your bait without you having to find them, but not always.
- If you’re not getting bites, move to a different location and drill new holes, especially if you’re see others catching fish.
- Perch are a schooling fish. Once you find them, the action can be fast.
Ice fishing rules
Ice fishing rules are slightly different than general fishing for public safety and general crowding. Be sure to check the official fishing regulations booklet for details.
- An angler can fish with up to five poles or lines at a time, and have up to five hooks per line. All lines must be attended by the angler. A two-pole validation does not allow more than five lines while ice fishing. Some waters are managed under special rules that limit the number of poles or bait while ice fishing, so be sure to check fishing regulations for exceptions.
- Statewide daily trout limit is six fish. There is no limit on perch, bluegill or crappie. Check the rules for the waters you are fishing for any special regulations that may apply.
- Fishing is allowed only through a hole up to 10 inches in diameter.
- There are no restrictions on the number of holes.
- Gaff hooks may be used only to land fish through a hole cut or broken in the ice in waters that have no length restrictions or harvest closures for that species.
- Anglers who use any enclosure or shelter for ice fishing and plan to leave it unattended overnight on the ice, must have the owner’s name, telephone number, and current address legibly marked on two opposing sides. Shelters must be removed from the ice before the spring thaw.
