New Hampshire Ice Fishing Rules: Licenses, Lines, Shanties, and Limits
October 18, 2026
Ice fishing laws in New Hampshire change depending on which lake you stand on. Most waters allow six lines per angler, but lake trout lakes allow two, and some Maine border waters allow five or even two.
You also face a fixed April 1 shanty deadline, a single-hook rule for bait, and a few waters where salmon can never be taken through the ice. This article walks you through licensing, seasons, gear, shelters, limits, vehicles, and bait so you know what applies before you drill your first hole.
Important Note: Rules in this article come from New Hampshire Fish and Game digests and state statutes. Regulations are updated each year, so check the current digest for your specific lake before you go. Also check ice thickness yourself; no regulation tells you whether the ice is safe.
Do You Need a Fishing License to Ice Fish in New Hampshire
Yes, in most cases. According to the New Hampshire Fish and Game FAQ page, all persons 16 years or older need a license to fish in freshwater or saltwater in New Hampshire. That includes ice fishing, and a standard freshwater license covers it.
You can buy a license online, by mail, or in person. Fishing and hunting licenses are valid January 1 through December 31 annually, and agents include Fish and Game offices, license agents, and some town or city clerks.
There is one free option. New Hampshire has two Free Fishing Days per year, where residents and non-residents can fish without a license: the first Saturday in June and the third Saturday in January. The January date falls right in the middle of ice season, which makes it a good day to try the sport.
Penalties for skipping the license add up quickly. LegalClarity reports that fishing without a valid license carries a fine of up to $93 for a first offense under RSA 214:18, with repeat violations leading to steeper penalties. That figure was published in an older summary, so confirm current amounts with Fish and Game.
Ice Fishing Seasons and Open Waters in New Hampshire
For most lakes and ponds, there is no fixed calendar date. The Central New Hampshire Chamber of Commerce explains that ice fishing in most New Hampshire lakes and ponds begins at “ice-in” and ends at “ice-out.” In practice, those declarations usually fall between late December and mid-April, but can vary depending on weather and safety conditions.
Some waters run on a set schedule instead. Lake trout waters have a defined ice fishing season of January 1 through March 31. The same dates apply to NH-Maine interstate waters, where ice fishing is allowed only from January 1 to March 31 in lakes and ponds (except cusk and salmon).
| Water Type | Ice Fishing Season | Notes |
|---|---|---|
| Most lakes and ponds | Ice-in to ice-out (typically late December to mid-April) | Warmwater species such as perch, pickerel, crappie, and bass |
| Lake trout and salmon lakes | January 1 to March 31 | No salmon through the ice |
| NH-Maine interstate lakes and ponds | January 1 to March 31 | Cusk and salmon excepted |
| Designated trout ponds | Closed to ice fishing | Open-water season only |
| Most rivers and streams | Closed to fishing through the ice | Unless a river’s special rules say otherwise |
Salmon get special protection. The state reminds anglers that salmon may never be taken through the ice, and it is advisable to cut the line as close to the salmon’s mouth as possible rather than remove the fish from the water.
Rivers are mostly off limits. Fishing through the ice, from the ice, or from any object supported by the ice is prohibited unless specified for a particular river in the special rules. On lake trout and salmon lakes, from April 1 through December 31, no person may take fish through the ice, from the ice, or from any object supported by the ice.
Pro Tip: Check ice thickness in several spots, starting at the shore. Visit NH advises looking for solid blue-black ice at least 4 to 6 inches thick for a few well-spaced people, and 8 to 10 inches to support off-highway recreational vehicles.
Line, Tip-Up and Hook Limits for Ice Fishing in New Hampshire
Line limits are where New Hampshire gets confusing. The state’s ice fishing page says most NH waters allow 6 devices (lines) per person when ice fishing, and that number counts both tip-ups and jig rods. Tip-ups consist of a submerged spool and line rig suspended from the ice, with a flag that pops up when a fish takes the bait.
The limit applies per angler, not per group. A fishing buddy gets their own six lines, but each licensed angler should be on the ice tending their own gear.
| Where You Are Fishing | Line Limit Per Person |
|---|---|
| Most New Hampshire waters | 6 |
| NH-Maine border waters | 5 |
| Great East Lake | 2 |
| Designated lake trout and salmon lakes | 2 |
Cusk fishing is a separate allowance. In addition to the normal number of lines allowed, up to 6 cusk fishing lines may also be used. Any species other than cusk caught on a cusk line must be released immediately by cutting the line without removing the fish from the water.
Hooks are limited too. Only single hooks with a single hook-point may be used with bait while ice fishing, so a baited treble hook is not legal. On lake trout lakes, you must use a single baited hook, an artificial lure, or flies to take fish through the ice.
Ice Fishing Hole Size Rules in New Hampshire
The sources I reviewed did not publish a statewide maximum hole diameter for New Hampshire. Several other states do set one, so this is a rule many out-of-state anglers assume exists here.
Practical limits still apply. The auger you choose for tip-ups and jigging should be wide enough to land a fish but no larger than you need, because open holes are a hazard to snowmobiles, ATVs, and other anglers walking after dark.
If you leave a shanty on the ice, state law requires clear ownership marking, covered in the shelter section below. Check the current Fish and Game digest or call a regional office if you plan to cut unusually large holes, such as for a group event.
Ice Shelter and Shanty Rules in New Hampshire
New Hampshire calls these structures bob houses or smelt shanties, and the law about them is strict. Under RSA 211:17-a, anyone owning or placing a smelt shanty or bob-house on the ice must clearly mark the owner’s name and address on the outside of the door.
The state’s ice fishing digest adds a visibility requirement. Bob houses must be removed from public waters, public property or private property no later than April 1, and must carry 12 square inches of reflective material halfway up the outside of each side.
Missing the deadline is expensive. An owner who leaves a structure on public property, public waters, or another person’s property without permission after April 1 is guilty of a violation, and the owner’s fishing license is suspended for one year. Fish and Game may also claim the structure and its contents and sell them at auction.
Maine Border Waters
Interstate waters have tighter timing. Under N.H. Admin. Code Fis 410.02, shacks may not be placed on the ice more than 3 days before waters open to ice fishing, must be labeled in 2 inch letters with the owner’s name and address, and must be removed within 3 days after the waters close.
Common Mistake: Assuming April 1 applies everywhere. On NH-Maine interstate waters, the shack removal clock is tied to the January 1 to March 31 season, so you may need to pull your shelter days before April 1.
Bag, Size and Species Limits for Ice Fishing in New Hampshire
Most ice fishing limits sit in the Fish and Game lakes and ponds rules. For trout, the New Hampshire eRegulations page lists a through-the-ice limit of 2 fish daily, with no length limit on general waters.
Lake trout and salmon lakes are tighter. From January 1 to March 31, the combined daily bag limit for all trout species is 2 fish, and the daily limit for lake trout is 2 fish. The digest lists a minimum length of 15 inches for trout, lake trout, and landlocked salmon, and the head and tail must remain intact while on or leaving the waters of the state.
The eRegulations page also shows a change between years: the lake trout minimum length was listed as 18 inches under the 2025 regulations and 15 inches under the 2026 regulations. If you fish lake trout waters, confirm the number on the current digest.
| Species or Water | Key Limit |
|---|---|
| Trout through the ice (general waters) | 2 fish daily, no length limit |
| Lake trout lakes (Jan. 1 to Mar. 31) | 2 trout daily combined, 15 inch minimum |
| Landlocked salmon | Cannot be taken through the ice |
| Great East Lake (lake trout) | 16 inch minimum |
| Umbagog Lake (brook trout) | 18 inch minimum, 1 fish daily |
The last two rows come from interstate rules. Great East Lake has a 16 inch lake trout minimum, and Umbagog Lake has an 18 inch brook trout minimum with a daily limit of 1 fish. A portion of Umbagog Lake is also closed to ice fishing. For warmwater species like perch, pickerel, and crappie, check the species chart in the angler’s digest.
Vehicle, ATV and Snowmobile Rules on the Ice in New Hampshire
The fishing digests I reviewed do not spell out vehicle rules on the ice, because those fall under off-highway recreational vehicle (OHRV) and snowmobile law. The practical issue is ice strength. Visit NH notes that ice 8-10 inches deep can support OHRV activity, but you should check the ice in multiple locations starting from the shore.
Before you drive onto a lake, confirm three things:
- Your snowmobile or ATV is registered and you follow OHRV rules for the water you are crossing.
- The lake or pond allows motorized access; some waters, wildlife areas, and private shorelines restrict it.
- Your route is clear of pressure ridges, springs, inlets, and open water.
Registering through Fish and Game and reading the current OHRV rules is the safest route for any machine heading onto the ice. Cars and trucks add far more weight than sleds, so many anglers skip them entirely.

Live Bait Rules for Ice Fishing in New Hampshire
New Hampshire defines bait broadly. Fish and Game states that baited hooks must have only a single hook with a single hook point per ice fishing device, and bait is defined as “any ingestible substance.” Corn is allowed: corn may be used for bait in New Hampshire waters.
Live baitfish must come from approved sources. You must purchase baitfish from a New Hampshire bait dealer or capture your own baitfish from New Hampshire waters. Moving fish across state lines or between waters is how invasive species spread, which is why LegalClarity notes that the use of live fish as bait is restricted in certain waters to prevent the introduction of invasive species.
Border waters have a stricter list. On NH-Maine interstate waters, it is unlawful to take, sell or possess for use as bait pickerel, goldfish, yellow perch, white perch, bass, sunfish, crappie, horned pout, carp or any spiny-finned fish, dead or living.
Pro Tip: Buy bait locally from a licensed New Hampshire dealer and keep your receipt. If you are fishing a border lake, ask the dealer which baitfish are legal there before you buy.
If you also use other methods in New Hampshire waters, see our guide to bowfishing laws in New Hampshire for the rules that apply outside ice season.
Ice season rewards anglers who read the rules for their specific lake. Confirm your line limit, mark your shanty with your name, address, and reflective tape, and plan to pull it before April 1 or sooner on border waters.
