Freshwater Fishing in Maine: Lakes, Species and the Rules That Catch People Out
Maine freshwater fishing: what lives in the lakes, the North and South zone rules, season dates, bag and length limits, licence costs, and where a beginner should actually start.
Maine has roughly 6,000 lakes and ponds and more than 32,000 miles of rivers and streams. The fishing is genuinely excellent. What trips visitors up is not finding water, it is the rulebook: Maine runs two zones with different seasons and limits, and then lets individual waters override both.
This page covers what lives in the lakes, what you may keep, and where a beginner should start. For trout specifically, including the State Heritage Fish waters, see the Maine trout fishing guide. For the coast, see the saltwater guide.
What actually lives in Maine lakes
Coldwater species, the reason most people come:
- Brook trout. Maine’s native fish and, in IFW’s own words, the state “supports the most extensive distribution and abundance of wild brook trout in their native range within the United States”. More than 1,200 lakes and ponds are managed for them, around 60% self-sustaining without stocking. Technically a char, not a trout.
- Landlocked salmon. Native to only four Maine watersheds, now widespread. Sebago Lake is the water they are named for.
- Togue, or lake trout. Maine’s other native char, holding deep in the big cold lakes. Note these are the same fish: if a guide lists “lake trout and togue” separately, it does not know what it is talking about.
- Brown trout and rainbow trout, both introduced and largely maintained by stocking. Browns tolerate warmer water than brook trout.
- Splake (a brook trout and togue cross) and Arctic charr, a glacial relic surviving in only a handful of Maine ponds.
Warmwater and other species:
- Largemouth and smallmouth bass. Smallmouth prefer cooler, rockier water; largemouth like warm and weedy.
- White and yellow perch, pickerel, and assorted panfish. Unlimited under general law.
- Whitefish, limited to three a day.
- Smelt, both a sport fish, limited to two quarts, and the forage that feeds the salmon fishery.
Closed to all fishing: sea-run Atlantic salmon, redfin pickerel and swamp darter are endangered or threatened species.
The two-zone system
Maine splits at a line that runs through the middle of two counties, so knowing which county you are in is not enough.
North Zone: Aroostook, Piscataquis, Somerset, Franklin, Penobscot north of Routes 11 and 157, and Oxford north of the Androscoggin River.
South Zone: York, Cumberland, Androscoggin, Kennebec, Sagadahoc, Lincoln, Waldo, Knox, Hancock, Washington, Penobscot south of Routes 11 and 157, and Oxford south of the Androscoggin River.
IFW’s own reasoning explains the whole logic: the North Zone holds abundant wild and native coldwater fish, so its rules protect them. The South Zone is predominantly stocked or warmwater, so its rules maximise opportunity, including year-round fishing.
Seasons
| Where | Open | Closed |
|---|---|---|
| North Zone lakes and ponds | April 1 to September 30 | October 1 to March 31, closed to all fishing |
| Both zones, rivers, streams, brooks | April 1 to August 15 | October 1 to March 31, closed to all fishing |
| Both zones, rivers, streams, brooks | August 16 to September 30, artificial lures or flies only | |
| South Zone lakes and ponds | January 1 to December 31, ice and open water | Open year round |
From August 16 to September 30 in flowing water, the daily bag also drops to one brook trout and one landlocked salmon, on top of the artificial-only rule.
Bag and length limits
| Species | Daily bag and possession | Lakes and ponds | Rivers, streams, brooks |
|---|---|---|---|
| Brook trout (includes splake and Arctic charr) | 5, but only 2 from South Zone lakes and ponds | 6” minimum | 6” minimum |
| Brown trout | 2 | 14” minimum | 6” min and 25” max |
| Rainbow trout | 2 | 12” minimum | 6” minimum |
| Landlocked salmon | 2 | 14” minimum | 14” min and 25” max |
| Togue (lake trout) | 2 | 18” minimum | 18” minimum |
| Bass (largemouth and smallmouth) | North Zone: unlimited. South Zone: 2 | None / no minimum, only 1 may exceed 14” | |
| Whitefish | 3 | None | |
| Smelt | 2 quarts | None | |
| Species not listed above | Unlimited | None |
Two traps. Splake and Arctic charr count inside the brook trout limit, not separately. And brown trout and landlocked salmon carry a 25-inch maximum in flowing water, so a genuinely big fish from a river goes back. Rainbow trout have no such cap.
Every one of these can be overridden by a special law code on a specific water. Check the S-code before you fish.
Where to start as a beginner
The honest answer is bass in the North Zone, and the reason is regulatory rather than romantic: general law sets no minimum length and no bag limit on bass there. Nothing hinges on measuring a fish correctly under pressure, or on telling a brook trout from a splake. Perch, pickerel and other unlisted species are unlimited statewide for the same reason.
What to avoid at first: brook trout and salmon water. The length limits are tight, the difference between species matters legally, and the best waters tend to carry extra restrictions on top of general law.
The big lakes, by the state’s own numbers
Moosehead Lake is the largest in Maine. IFW’s survey chart gives 74,890 acres and a maximum depth of 246 feet. It holds brook trout, landlocked salmon and togue, and is big enough that you can fish it for days without covering it.
Sebago Lake is second in area at 29,992 acres but the deepest in the state: 310 feet at maximum, 106 feet mean, with 98.2 miles of shoreline. Landlocked salmon take their name from it.
The Rangeley chain (Rangeley, Mooselookmeguntic, Richardson, Aziscohos) is the classic brook trout and salmon destination.
The Belgrade Lakes are the accessible central Maine option, better known for bass and perch, and easy to reach from Augusta or Waterville.
Getting to the water costs something too. Sebago Lake State Park charges day use per person, not per vehicle: $6 for Maine resident adults, $8 for non-residents, $1 for children 5 to 11, free under 5 and for Maine residents 65 and over. Bring cash, since only about 15 state park locations take cards.
Licences
Anyone 16 or older needs one. These are the 2026 fees, before the agent fee:
| Licence | Resident | Non-resident |
|---|---|---|
| Season | $30 | $83 |
| 15-day | — | $66 |
| 7-day | — | $62 |
| 3-day | — | $30 |
| 1-day | $18 | $18 |
The 15-day non-resident licence costs only $4 more than the 7-day, and can be exchanged later for a full season licence for $17 plus the agent fee. Buying the shorter one rarely makes sense.
A Maine freshwater licence also exempts you from the saltwater registry, so it covers the coast as well. A Lifetime Licence does not.
Maine runs free fishing days each year when no licence is required. Best Days to Fish tracks them by state.
Fishing through the ice
South Zone lakes and ponds stay open all year, which is where most Maine ice fishing happens. IFW’s guidelines, for new clear ice only: stay off under 4 inches, 4 inches for foot travel, 5 to 7 for a snowmobile or ATV, 8 to 12 for most cars, 12 to 15 for a medium truck.
White or snow ice is only about half as strong at the same thickness, and IFW does not recommend driving on ice at all. See the ice fishing guide for the rest.
Before you go
- Look up the specific water. General law is the default, not the rule.
- Work out which zone you are in. Oxford and Penobscot are split down the middle.
- Check whether your pond is a State Heritage Fish water, where live bait is a Class E crime. See the trout guide.
- Season sets what is legal, but water temperature and pressure decide whether fish feed. Best Days to Fish scores days on solunar timing and barometric pressure, with pages for smallmouth bass, largemouth bass and brown trout.
Common Questions
What types of fish are in Maine lakes?
Maine manages five coldwater species in its lakes: brook trout (a native char), landlocked salmon, togue or lake trout (also a native char), and introduced brown and rainbow trout. Warmwater species include largemouth and smallmouth bass, white and yellow perch, pickerel and whitefish, plus smelt, which are both a sport fish and the forage that feeds the salmon. Splake and Arctic charr occur in a small number of waters. Sea-run Atlantic salmon, redfin pickerel and swamp darter are endangered or threatened and closed to all fishing.
What is the best freshwater fishing in Maine for beginners?
Bass in the North Zone, where general law sets no minimum length and no bag limit at all, so nothing hinges on measuring your catch correctly. Perch, pickerel and other unlisted species are also unlimited statewide. Avoid starting on brook trout or salmon water, where the length limits are tight and many individual waters carry extra restrictions.
What are the best lakes to fish in Maine?
Moosehead is the biggest at 74,890 acres and 246 feet deep, holding brook trout, landlocked salmon and togue. Sebago is second at 29,992 acres and the deepest in the state at 310 feet, and is the water landlocked salmon are named for. The Rangeley chain is the classic brook trout and salmon destination, and the Belgrade Lakes are the accessible bass and perch option in central Maine.
Do I need a license to fish in Maine lakes?
Yes, anyone 16 or older. 2026 fees are $30 for a Maine resident season licence and $83 for a non-resident, before the agent fee. Non-residents can also buy 1-day at $18, 3-day at $30, 7-day at $62 or 15-day at $66. Note the 15-day costs only $4 more than the 7-day.
When does freshwater fishing season open in Maine?
April 1 for most waters. North Zone lakes and ponds run April 1 to September 30 then close entirely. Rivers and streams statewide run April 1 to August 15, then switch to artificial lures or flies only from August 16 to September 30. South Zone lakes and ponds are open year round for both ice and open water fishing.
