Henry's Lake Ice Fishing Tournament is an annual winter event held on Henry's Lake, a large reservoir on the Idaho-Wyoming border near Island Park. The tournament typically takes place in January or February, though exact dates shift year to year. Entry is open to anglers of most skill levels, and the event draws both locals and visitors who want to fish for trophy-sized cutthroat trout and lake trout under the ice.
The Henry's Lake Foundation organizes and runs the tournament. They set the entry fee, announce the dates each season, and manage the weigh-in and prize structure. Because dates and rules can change, checking the Henry's Lake Foundation's website or calling ahead is the only way to confirm what year's tournament will look like before you commit to the trip.

What you need to fish Henry's Lake in winter
Before you enter the tournament or fish the lake at all, you need an Idaho fishing license and a Henry's Lake permit. The permit is separate from your license and is required specifically for Henry's Lake. Both are available through the Idaho Department of Fish and Game website or at sporting goods retailers in the area. The permit has an annual cost and daily options, depending on how long you plan to fish.
For ice fishing itself, you will need an ice auger (hand-crank or powered), a fishing rod rated for ice fishing, line suited to the species you are targeting, and a shelter or windbreak if you plan to spend hours on the ice. Many anglers use tip-ups or jigging rods. Henry's Lake produces large fish, so heavier line and sturdy equipment are worth the investment. Bring a depth finder if you have one — knowing where the trout are holding under the ice saves time and effort.
Safety gear is not optional. Wear a personal flotation device rated for ice fishing, carry a rope and ice picks, and never fish alone. Bring a charged cell phone, extra clothing layers, and hand and foot warmers. Henry's Lake is a large body of water at high elevation, and conditions can change quickly. Tell someone on shore where you are fishing and when you expect to return.
Ice conditions and timing on Henry's Lake
Henry's Lake typically freezes solid enough for ice fishing by late December or early January, which is why the tournament is scheduled for winter months. However, ice thickness and safety vary from year to year and even from week to week. Before you drive to the lake, contact the Henry's Lake Foundation, a local bait and tackle shop, or the Island Park ranger station to ask about current ice conditions. Do not assume the lake is safe to fish based on the calendar alone.
The lake sits at 6,472 feet elevation, and weather can be severe. Wind, snow, and temperature swings are common. Some areas of the lake freeze thicker than others, and springs and inlet streams can create thin-ice zones that are dangerous. Local anglers know where these hazards are — talking to people who fish the lake regularly before your trip can save you from a costly or dangerous mistake.
Tournament entry and prize structure
Entry into the Henry's Lake Ice Fishing Tournament is handled directly by the Henry's Lake Foundation. The entry fee, the number of divisions, and the prize categories change from year to year based on participation and sponsorship. Some tournaments have categories for largest fish, most fish, or youth divisions. Prize money or merchandise is typically awarded to top finishers in each category.
To enter, you will usually need to register before the tournament starts — registration may close a few days before the event. The foundation will tell you where to weigh in your catch and what time the weigh-in closes. Bring a cooler to keep your fish fresh, and know the rules about which species count and any size restrictions that apply to the tournament specifically.
Where to stay and what to bring
Island Park, Idaho, is the closest town to Henry's Lake, about 30 minutes away by car. It has motels, cabins, and RV parks, though availability fills up during tournament season. Booking lodging well in advance is wise if you are traveling from out of state. Some anglers camp or stay in RVs year-round near the lake, and there are Forest Service campgrounds in the area, though many close in winter.
Bring more food and water than you think you will need. The lake is remote, and services are limited. A thermos of hot coffee or soup, snacks, and extra water are essential for a full day on the ice. If you are new to ice fishing or to Henry's Lake, consider hiring a local guide for at least one day — guides know the productive areas, the hazards, and the current fish behavior, and the cost is often worth the education and safety.
Fish species and what to expect
Henry's Lake is famous for large cutthroat trout, some exceeding 20 inches. The lake also holds lake trout (mackinaw), which can grow even larger. Both species are caught through the ice, though cutthroat are the primary target for most tournament anglers. The lake is managed for trophy fishing, so there are regulations on how many fish you can keep and what sizes are legal.
Fishing pressure is heaviest during the tournament, but the lake is large enough that patient anglers can find fish. Early morning and late afternoon are typically the most productive times. Jigging with live bait or small lures works well for both species. Ask local tackle shops what has been working recently — conditions change, and what worked last week may not work this week.
Preparing for your first tournament
If this is your first time fishing Henry's Lake or your first ice fishing tournament, start by talking to people who have done it. Online fishing forums focused on Idaho, local Facebook groups, and tackle shops in Island Park are good places to ask questions. Many experienced anglers are happy to share tips about where to fish, what to bring, and what to expect.
Practice setting up your gear at home before you arrive. Know how to use your auger, how to tie your knots, and how to work your rod and reel in cold weather with gloves on. The lake is not the place to learn these things for the first time. Arrive a day or two early if you can, so you can scout the lake, check ice conditions in person, and get comfortable with the area before the tournament starts.
