Ice Fishing Laws in Wyoming: Lines, Licenses, Live Bait, and Shelter Rules

Ice fishing laws in Wyoming are mostly the same as the state’s open-water rules, but a handful of winter exceptions can change how many lines you run and what bait you can use. Get one of those exceptions wrong and a quiet day on the ice turns into a citation. Most anglers never read the fine print until a warden walks up.

This article walks you through the rules that matter most: licensing, seasons, lines and tip-ups, hole size, shelters, limits, vehicles, and live bait. Where the published rules are silent or vary by water, you’ll see a clear note so you know to check the current Wyoming Game and Fish Department (WGFD) regulation booklet before your trip.

Important Note: Wyoming regulations are updated regularly and individual waters carry their own exceptions. Treat this article as a planning guide and confirm the named-water entry in the current WGFD fishing regulations before you head out.

Do You Need a Fishing License to Ice Fish in [State]

Yes. Ice fishing is fishing, so the same licensing rules apply as in summer. One source covering Wyoming ice fishing notes that Wyoming Game and Fish regulations require a valid fishing license for all anglers, and some wilderness and tribal waters have additional permit requirements. If you plan to fish on tribal land, such as parts of the Wind River Reservation, research that destination’s permit rules separately.

The good news is that the extra gear doesn’t cost extra. According to WGFD, a Wyoming angler may use two poles or lines while fishing, and no additional license is required. That covers the standard two-line setup on most waters.

Flaming Gorge is a special case. The Wyoming Game and Fish Commission’s Chapter 46 rules include a provision allowing a Utah resident fishing license and a valid Wyoming reciprocal fishing stamp to be used on the Wyoming portions of the reservoir. If you cross the state line while fishing there, read that provision first.

Fee schedules change from year to year, so check the WGFD license page for current resident and nonresident prices rather than relying on a number printed in an article.

Ice Fishing Seasons and Open Waters in [State]

Wyoming is one of the more open states for winter anglers. Under Chapter 46, fishing is permitted year-round, 24 hours a day, in any of the state’s waters except where the Commission provides otherwise for specific areas. There is no statewide ice fishing season to wait for; the ice itself decides when you can fish.

The exceptions are the closures. Some waters shut down to ice fishing or all fishing on specific dates. For example, the WGFD’s Area 2 regulations list a number of waters in the Wind River and Bighorn drainages and state plainly that one entry is closed to ice fishing. Another summary notes that Bump Sullivan Reservoir is closed November 1 through the last day of February.

The same summary adds a useful distinction: some waters prohibit ice fishing or watercraft during specific dates even when other forms of fishing may be legal. Always read the entry for the exact water you plan to fish.

When the Ice Is Actually Safe

Legal and safe are two different questions. WGFD advises that safe fishing ice should be at least four inches thick, and anglers should check thickness every 100 to 150 feet. Wyoming’s cold snaps are often followed by warm spells, so conditions can change within days.

Ice color matters too. WGFD guidance reported by Your Wyoming Link says clear ice is stronger than cloudy or white ice, and white ice calls for double the thickness, a minimum of eight inches.

Line, Tip-Up and Hook Limits for Ice Fishing in [State]

This is where Wyoming’s ice rules differ most from summer rules. The statewide baseline is two rods or poles with lines and hooks attached and the angler in attendance, with no more than three single-hooked devices on any line. Tip-ups are explicitly legal: it is legal to use hand lines, set lines, poles, or tip-ups when fishing through the ice and the angler is in attendance.

On a list of designated waters, you can go well beyond two lines. The Special Winter Ice Fishing Provision allows more than two lines only during the ice-covered period, with a maximum of six lines at any time. Waters on the list include Alcova, Boysen, Fontenelle, Glendo, Keyhole, Lake DeSmet, Pathfinder, Seminoe, and Flaming Gorge, among others.

The older Chapter 46 text adds one more condition for the multi-line setup: each line shall bear no more than one hook, artificial fly or lure. Newer summaries of the rule focus on the name tag, distance, and line-checking requirements, so confirm the hook language in the current booklet.

Rule	Standard Waters	Special Winter Waters
Maximum lines	2	Up to 6 (ice-covered period only)
Name on each line or tip-up	Recommended practice	Required when using more than 2 lines
Distance from lines	Angler in attendance	No more than 300 yards
Who checks the lines	You	You (required)

Common Mistake: Attendance is stricter than most anglers think. WGFD’s Lander Region has said sleeping in the camper or truck is not attendance even within 300 yards, and walking off to check in a fish during a derby does not count as attending your other lines.

Ice Fishing Hole Size Rules in [State]

None of the Wyoming sources I found set a statewide maximum or minimum auger diameter for ice fishing holes. The Chapter 46 text covers lines, hooks, tip-ups, and attendance, but it doesn’t specify a hole width. If you’ve seen a number quoted elsewhere, treat it as unconfirmed until you see it in the WGFD booklet.

What you can rely on is practical guidance. Wikipedia’s overview of ice fishing notes that the size of the hole depends on the type of fish sought, and generally about 8 inches is suggested. That’s enough for most trout, perch, and walleye, but pike and large lake trout may call for a wider hole.

Safety is the real hole-size issue. Keep holes no wider than you need, and mark abandoned ones, because a fresh hole refreezes as thin ice and can hide under snow. Check named-water entries in the regulation booklet in case a local rule says otherwise.

Ice Shelter and Shanty Rules in [State]

Wyoming’s regulations include a dedicated “Ice Fishing Shelters” section, which is part of the statewide rules. The text opens with language about any person utilizing an enclosed shelter, but the search snippet cuts off before the specific requirements. I couldn’t verify the exact wording, such as identification or removal deadlines, so read that section directly on the WGFD or eRegulations Wyoming page.

Plan on a few things regardless. Mark your shelter with your name or contact information, and remove it before the ice weakens in spring. Wyoming’s high-elevation lakes can deteriorate fast; one local guide warns that a lake showing 8 inches of ice at 8:00 AM can develop soft spots along the bank by 2:00 PM when the sun climbs in late winter.

If you fish on federal land, such as BLM or Forest Service ground near a reservoir, there may be separate rules on how long you can leave property unattended. Ask the local field office before you leave a shanty overnight.

Bag, Size and Species Limits for Ice Fishing in [State]

Daily and possession limits don’t change just because the water is frozen. The limits that apply in July apply in January, and they vary by drainage and by water. That’s why the same species can have different limits two reservoirs apart.

Walleye and sauger are the clearest example. In the Wind River drainage, including Boysen Reservoir, WGFD’s Lander Region notes that the creel limit on sauger is two, whereas six walleye can be harvested daily or kept in possession. Learn to tell the two apart before you start keeping fish.

Bighorn Lake downstream of the U.S. 14A causeway has its own table: walleye and sauger at six per day with no more than three sauger, and twelve in possession with no more than three sauger. Shovelnose sturgeon there are limited to two.

Fish handling rules matter on the ice, too. On Area 2 waters, walleye and sauger must be kept whole until you are off the water or ice and done fishing for the day, after which they can be filleted for transport. A separate summary says game fish may be filleted for transport with at least one square inch of skin retained for identification.

Vehicle, ATV and Snowmobile Rules on the Ice in [State]

I found no statewide statute in the research that specifically authorizes or bans vehicles on frozen Wyoming waters, so treat this as a safety and land-management question first. WGFD’s Lander Region is direct about the risk: it is not recommended to drive a vehicle onto the ice.

Walking requires at least 4 inches of clear, solid ice, or 8 inches if the ice is cloudy. Vehicles need far more than that, and thickness varies across a single lake near springs, inlets, and pressure ridges. Snowmobiles and ATVs are lighter than trucks but can still break through.

Access rules also depend on who manages the shoreline. State parks, BLM land, Forest Service land, and wildlife habitat management areas each set their own motorized-use rules, and some ban vehicles entirely in winter. Call the managing office before you drive anywhere near the water.

• Never travel alone on the ice.
• Carry ice picks around your neck and a throwable flotation device.
• Tell someone where you are going and when you plan to return.
• Wear a life jacket, which WGFD’s chief of fisheries recommends along with fishing with a partner.

Live Bait Rules for Ice Fishing in [State]

Live bait is the rule most winter anglers trip over, because Wyoming is restrictive. Live baitfish are allowed only on a short list of waters. In the Lander Region, WGFD says the only waters that allow live bait fish are the Wind River downstream from Boysen Reservoir, Boysen Reservoir, Ocean Lake, and Pilot Butte Reservoir. Other regions have their own lists, so check the water you plan to fish.

Purchase rules are strict. You must buy live bait from a licensed dealer, who must give you a receipt that you have to carry. Keep that receipt in your jacket, not back at the truck.

Live bait pairs well with tip-ups. WGFD explains that when you use live bait with tip-ups the bait supplies the action, so you aren’t constantly jigging the line. Where it’s legal, a lively sucker or minnow under a flag is a standard pike setup; one regional guide describes 6 to 8 inch suckers set 2 to 4 feet below the surface in 5 to 10 feet of water for early-ice pike.

Do not move live fish between waters. Wyoming promotes a “Don’t Move Live Fish” message on its regulations pages, and dumping leftover bait is a fast way to spread invasive species. Waters limited to artificial flies and lures prohibit bait of any kind, which WGFD defines as excluding living or dead organisms or edible parts thereof, natural or processed foodstuffs, scents, flavors or chemicals.

Pro Tip: Before each trip, pull up the current WGFD regulation booklet or the Wyoming statewide regulations page, confirm your water is on the Special Winter Ice Fishing list, and screenshot the entry. It takes two minutes and settles most questions in the field.

Wyoming rewards anglers who do their homework. Know your water’s line limit, carry your bait receipt, keep your name on every tip-up, and respect the ice.
