Is spearfishing allowed at Oswego?

No. New York permits taking fish by spear or speargun only in the marine and coastal district; Lake Ontario is fresh, non-tidal water where only angling is allowed.

What is the deepest structure in the harbour?

The west breakwater arm, with 8 m of water at its foot and a boulder toe. The east arm carries about 6 m on its lake face.

Does the sanctuary stop me diving?

No. It prohibits disturbing, removing or anchoring on shipwreck sites under 15 CFR § 922.223(a), not fishing or diving. The spear ban is separate and comes from state law.

Why is the visibility better here than on Lake Erie?

Deep, cold eastern-basin water. It also preserves wooden hulls far better than a warm shallow basin does.

Plan for cold: a drysuit or heavy semi-dry. The eastern basin stays cold and the thermal layering holds through the summer.

May to November. Ice forms only in the bays and eastern shallows from January to March.

Oswego spearfishing forecast — United States

Q: Are there wrecks at Oswego?

The eastern basin's deep cold water preserves wooden hulls, but no wreck list was pinned by a primary source in this research. The documented sites here are the harbour breakwaters.

Q: What is Ford Shoals?

A named shoal about 6 km west of the harbour in only 2 m of water — the shallowest charted hazard on this stretch. Fully exposed, so a flat-calm site only.

The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.

How we score the water

Our own model

Our own forecast engine — not a third-party widget. It weighs these water factors into one go-or-stay verdict for this coast; the 0–10 dial is that verdict, read out as a number.

Swell & wave memory: Height, period and direction of the swell, plus the wake of recent storms — an old storm still stirs the water, and the engine remembers.
Wind & gusts: Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
Tides — none here: The Great Lakes are fresh water: there is no tide, so this factor never moves the verdict. The level is pushed around by wind setup and seiche instead.
Water temperature: Lake surface temperature from NOAA GLERL's GLSEA daily composite, not an ocean model — sharply cold water vetoes a green verdict.
Currents & outflow: Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
Rain runoff & air clarity: Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
Coast shape & exposure: How the coast faces the swell — a sheltered cove keeps the water clean; an exposed, head-on point takes a penalty.

Safety gates

Thunderstorm forecast — an instant red, no exceptions.
An official warning (MeteoAlarm / IPMA) — yellow, or red for the higher ranks.
Missing input data — a would-be green is capped to yellow rather than overstated.
Strong disagreement between forecast models — a green day is pulled back to yellow.
Night hours — where night spearfishing is banned by law the window is forced red; where it is legal (Australia outside NSW, New Zealand, South Africa) it is capped at yellow, never green.

It all folds into a single 0–10 score and one verdict: go or stay.

A forecast, not a guarantee — the sea has the last word.

SOLO is the biggest risk: underwater you can black out from lack of oxygen silently and fatally, with no one around. Solo is never truly «safe». Below are the best weather windows; carry a buoy, tell someone your plan and exit time, and any doubt — don't go.

In season now

no targets this month

Not a target — don't shoot

Lake trout🚫 no-take
Underwater spear only in the Michigan waters the 2026 regulations name: Lake Michigan from the MI/IN border north to the 45th parallel, a 2-mile strip in Green Bay to the Ford River mouth, a 5-mile strip from Point Detour to the Brevort River, Lake Huron from the Thunder Bay River pier to Fort Gratiot Light, Lake Erie to the Celeron Island line and Lake Superior to the St. Marys River. Grand Traverse Bay, Stannard Rock, Big Reef and a 4.5-mile ring round Isle Royale are excluded. 15 in minimum; season and limit run by management unit. Nowhere else in the eight states.
Lake whitefish🚫 no-take
On Michigan's year-round spear list in all state waters except designated trout lakes and streams and the Michigan/Wisconsin boundary waters. Wisconsin treats it as a game fish and bans the spear on it in the outlying (Great Lakes) waters.
Cisco (lake herring)🚫 no-take
On Michigan's year-round spear list and a genuine Great Lakes target there. In Ohio the cisco (lake herring) is a state endangered species — possession is prohibited in every Ohio water.
Walleye🚫 no-take
Underwater spear only in the named 2026 Michigan waters (Lake Michigan to the 45th parallel, the Green Bay and north-shore strips, Huron, Erie, Superior; Grand Traverse Bay, Stannard Rock, Big Reef and the 4.5-mile ring round Isle Royale excluded): 15 in minimum, 5 a day. Lake St. Clair, the St. Clair River and the Detroit River are not in the row at all. Every other state on the lakes bans the spear on walleye outright.
Northern pike🚫 no-take
Michigan: underwater spear in the named 2026 waters (Lake Michigan to the 45th parallel, Huron from the Thunder Bay River pier to Fort Gratiot Light, Erie, Superior; Grand Traverse Bay, Stannard Rock, Big Reef and the 4.5-mile ring round Isle Royale excluded), possession season 1 July – 15 March, 24 in minimum, 2 a day; plus a separate hand-spear ice season 1 December – 15 March. Wisconsin allows pike by spear only through the ice on Lake Superior — never underwater.
Muskellunge (musky)🚫 no-take
Michigan only, and only by hand spear through the ice 1 December – 15 March: muskellunge is not on the 2026 underwater-spear list at all. On Lake Erie, Lake St. Clair, the Detroit River and the St. Clair River it is hook and line only, by name.
Smallmouth bass🚫 no-take
No Great Lakes state authorises a spear on black bass. Michigan, Wisconsin, Minnesota, Illinois, Indiana and Pennsylvania all publish enumerating lists and bass is on none of them; New York bans every spear in fresh water.
Largemouth bass🚫 no-take
Same rule as the smallmouth: no Great Lakes state puts black bass on a spear list, and New York bans the spear in fresh water altogether.
Yellow perch🚫 no-take
Wisconsin is the one place a diver can shoot it: panfish carve-out on the outlying waters, skin or scuba, sunrise to sunset, while the rough-fish spearing season is open. Michigan allows it only by hand spear through the ice on Lake St. Clair, 1 December – 15 March.
Burbot🚫 no-take
Pennsylvania's burbot fishery is the one real underwater lane in the eastern lakes: scuba divers only, non-mechanical spear or gig, at least 60 ft, 1 June – 30 September, 5 a day, no minimum size, fishing licence plus Lake Erie permit. Michigan and Wisconsin carry burbot on their year-round rough-fish lists.
Common carp🚫 no-take
The one species spearable almost everywhere a spear is legal at all: Michigan and Wisconsin year-round, Ohio as forage fish, Pennsylvania under 58 Pa. Code 63.8 with a non-mechanical spear. New York gives you a bow instead, carp only, 15 May – 30 September. Illinois and Indiana list it but neither names Lake Michigan as a spear water.
White sucker🚫 no-take
Rough fish in Michigan, Wisconsin, Ohio and Pennsylvania, so it is lawful quarry wherever those states let a spear in the water. Identify the fish first: Ohio and New York protect the longnose sucker, and Wisconsin excludes any listed threatened or endangered sucker from its rough-fish class.
Longnose sucker🚫 no-take
State endangered in Ohio and threatened in New York — fishing for it and possessing it are illegal there, catch and release included in New York. Elsewhere it falls under the general 'suckers' allowance, which is exactly why a diver must tell the sucker species apart before shooting.
Freshwater drum (sheepshead)🚫 no-take
Ohio's forage-fish class names the sheepshead by name, so it is a real Lake Erie spear target. Michigan and Wisconsin carry it year-round; Pennsylvania's 58 Pa. Code 63.8 list does not include it, so it may not be speared there.
Channel catfish🚫 no-take
Michigan's year-round list and Pennsylvania's 58 Pa. Code 63.8 list both name catfish; Illinois names channel catfish expressly. Minnesota allows catfish by spear only from a dark house through the ice, never underwater.
Bowfin🚫 no-take
Rough fish in Michigan, Wisconsin and Ohio, with no bag limit at all in Minnesota's inland waters. Illinois and Indiana both list it, but neither names Lake Michigan among its spear waters.
Longnose gar🚫 no-take
Rough fish across the western lakes; Minnesota caps the take at 10 in its inland waters. In Ohio the alligator, shortnose and spotted gar are state endangered even though 'gar' is a forage fish — identify the gar before you shoot.
Round goby (invasive)🚫 no-take
Illinois is the only one of the eight states that names the round goby as a lawful spear target, and it never names Lake Michigan among its spear waters; no live possession either. Michigan and Minnesota only ban possessing or transporting it alive — a ban is not a permission to shoot it. And the fish is too small to be a real target.
Sea lamprey (invasive)🚫 no-take
Wisconsin's rough-fish definition includes lamprey, so it may be speared on the outlying waters; Illinois lists it too, with no live possession. In Michigan it is not on the spear list at all, and fishing anywhere in a fish ladder or within 100 feet of a lamprey control weir is prohibited.
Lake sturgeon (protected)🚫 no-take
Protected in all eight states — endangered or threatened, no open season, possession prohibited. Michigan's only spear season is an inland, pre-registered winter season on Black Lake; in New York even catch and release is illegal. Never a target on any Great Lake.
Chinook (king) salmon🚫 no-take
No Great Lakes state authorises a spear on salmon. Michigan's table lists only lake trout among the salmonids; the salmon stamps sold in Illinois, Wisconsin, Indiana and Pennsylvania are for rod and line, not for a spear.
Coho (silver) salmon🚫 no-take
Same answer as the chinook: not on a single spear list in the eight states, and New York bans the spear in fresh water outright.
Steelhead (migratory rainbow trout)🚫 no-take
Nowhere spearable. On top of that, Pennsylvania bans spearfishing in and along every Lake Erie tributary stream, and Indiana bans even possessing a spear on Trail Creek, the East and West Branch Little Calumet, Salt Creek, Burns Ditch, Deep River below the Lake George dam and the Galena River — the steelhead creeks are the easiest place to break the law by accident.
Rainbow smelt🚫 no-take
On the Michigan and Wisconsin rough-fish lists. On Minnesota's waters of Lake Superior smelt is a dip-net and minnow-seine fishery under Minn. R. 6262.0300, not a spear one.

Law

•Michigan is the only jurisdiction in the region with a purpose-built underwater-spearfishing regime: a FREE annual underwater spearfishing licence, mandatory and separate from the fishing licence, resident and non-resident alike. From the 2026 season the monthly online effort-and-harvest report is ABOLISHED — the DNR dropped the reporting and kept the licence. Fishing licence: resident $26/yr, non-resident $76/yr, $10 daily.
•Michigan, gear and conduct: breath-hold ONLY — scuba and rebreathers are prohibited while underwater spearfishing; daylight only (banned from 30 min after sunset to 30 min before sunrise); a speargun may be fired only while submerged and must be tethered to a line no longer than 20 ft (6 m); bands off the spear and the safety on when moving between areas and entering or leaving the water; never within 150 ft (46 m) of a designated swimming area, boat dock, boat access site or power intake. New for 2026: the use of bait, attractants or decoys while underwater spearfishing is prohibited, and the diver must be fully submerged when taking a fish.
•Wisconsin is the only state here that names SCUBA as lawful for underwater spearfishing («by skin and scuba diving») — but on the outlying waters (the Great Lakes) no GAME FISH may be speared: panfish, white/yellow/rock bass, bullheads and rough fish only, sunrise to sunset. Licence: resident $20/yr, non-resident $55/yr.
•New York and Minnesota: there is NO Great Lakes spearfishing. New York — ECL 11-1301(1)(a)/(c): spear and speargun are lawful only in the marine and coastal district. Minnesota — the underwater harpoon gun is authorised for INLAND waters only, for common carp and native rough fish, sunrise to sunset (Minn. Stat. 97C.371, Minn. R. 6262.0600); Lake Superior is closed.
•Pennsylvania: 58 Pa. Code 63.5 makes every method unlawful unless specifically authorised; 63.8 authorises spears and gigs for snakehead, carp, suckers and catfish, and 63.8(c) forbids a mechanically propelled spear — so a speargun is unlawful everywhere in PA. Ohio: its «forage fish» class (thirteen rough species) may be taken by any method except a short list that does not include spears, so spearing them is lawful — but Ohio publishes no rule permitting a spear on any game fish. Indiana and Illinois: their spear paragraphs do NOT name Lake Michigan — status unconfirmed.
•Fresh water is not the sea: there is no tide here (the level moves with wind setup and seiche, and NOAA CO-OPS publishes no tide predictions for Great Lakes stations at all), and in winter the ice and 1–4 °C water are the season's real hazard. This page reads the water temperature from NOAA GLERL (GLSEA ACSPO) rather than from the marine model, which answers nothing on these lakes.

Safety protocol

Sets: watch the wave trains ≥15 min before entering; Hmax ≈ 2×Hs. Lake waves are short-period (NWS: roughly 3–4 s on average in summer) and steep, and they grow with wind strength, fetch and how long the wind has blown — a lull promises nothing here; enter right after a full set passes and re-check at minute 30.
Exit FIRST: find your exit AND a backup before entering. On a breakwall or a boulder revetment a modest rise in wave height can make the exit impossible — plan for not being able to climb out, and leave while the exit is still easy.
Structural current: near piers, breakwalls and river mouths currents can form and strengthen when waves and surf pick up (NWS describes structural and rip currents at exactly these features) — stay well clear of piers and breakwalls, especially the side the waves are hitting, and of river mouths and channel outlets: that is where the current runs strongest (NWS). If one catches you anyway, never swim against it.
Cold: wetsuit per the lake-temperature chip (GLERL surface — below the thermocline it is colder still); cold water shortens the safe time in the water — plan short sessions, wear a thicker suit than you think you need, and get out at the first steady shiver. Where the limit sits depends on your exposure protection, your workload and you (NOAA).
Solo discipline: buoy up; tell someone the spot and exit time; conservative breath-hold (never push it in cold/murky/surfy water); visibility <3 m — don't enter.
Afternoon wind: on the Great Lakes, on sunny days with a light gradient wind, a lake breeze often sets in around midday and the chop can build quickly — plan to be out of the water by midday; when the chop builds, get out.
UV 11:00–15:00 (UVI ≥6): sunscreen and cover up on the surface interval.
Solo is a fundamental risk (hypoxic blackout with no buddy). Any doubt = No-go.

Spearfishing in Oswego: spots, seasons and rules

Updated 2026-09-04 · By Oleksandr, spearfisher

Oswego is a diving town with no spearfishing in it. New York ECL § 11-1301(1)(a) permits fish to be taken only by angling, and § 11-1301(1)(c) allows a spear or speargun only in the marine and coastal district, which is Atlantic and tidal water, not Lake Ontario. What Oswego has instead is the eastern basin: deep, cold water that preserves wooden hulls, the historic harbour of refuge with two breakwater arms in 6-8 m, and Ford Shoals in 2 m to the west. Honest caveat: no wreck list was pinned by a primary source here.

TL;DR

New York bans spearfishing in all of its fresh water. ECL § 11-1301(1)(a) allows only angling and (1)(c) confines the spear and speargun to the marine and coastal district, which Lake Ontario is not in.

Oswego is the historic port of the eastern basin and the entrance to the Oswego Canal; the deep, cold water there preserves wooden hulls. No wreck list was pinned by a primary source in this research.

The two breakwater arms are the local structure: about 6 m on the east face and 8 m at the foot of the west arm, the deepest in the harbour.

Oswego sits inside the Lake Ontario National Marine Sanctuary, which prohibits disturbing shipwreck sites — but not fishing. The spear ban is state law.

What can you dive at Oswego, and how deep?

Three sites, all structural, all boat- or kayak-access. The two harbour arms are the reliable pair — cold, deep-basin water that keeps the visibility good — and Ford Shoals is a flat-calm-only site in only 2 m. No wreck list was pinned by a primary source in this research, so this table is deliberately conservative. Every row is a dive site: New York bans the spear across all its fresh water.

Spot	Type	Depth	Level	Access	Notes
Ford Shoals	Reef	1.5-2.3 m	Snorkel on a flat day · dive only, NY spear ban	Kayak or small boat	Named shoal about 6 km west of the harbour in only 2 m of water — the shallowest charted hazard on this stretch and the reason ships came to grief here. Hard bottom, fully exposed; a flat-calm boat or kayak site.
Oswego East Breakwater	Jetty	3-6.3 m	Intermediate boat dive · dive only, NY spear ban
