6,449-acre Ii - Olhava - Taipale. North Finland coastal fishing map with an exact official national water-body boundary, EMODnet 2024 official Finnish hydrographic chart/DTM assessed contours, source-assessed fishing spots, official regional fish evidence, seasonal forage guidance, public-access review and current-rule links. Official Syke VHS 2022 named coastal water in Bothnian Bay. This child is clipped to the exact source polygon and a trip-scale ownership window. Coverage classes and uncertainty limits are disclosed; this is a fishing-planning chart, not a navigation chart or catch forecast. The water tops out around 5 m. The depth chart comes from EMODnet, with national hydrographic source-reference audit official hydrographic-chart depth models, so the contours are chart-derived rather than computer-modeled; no directly measured sounding coverage is claimed. What the data behind the map says about each species, season by season:
Kartalla Ii - Olhava - Taipale - North kattaa 2 610 hehtaaria, rantaviivaa 71.5 km, ja saaria on 53. Rantaviiva on voimakkaasti rikkonainen (indeksi 3.9) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Koko vesi on matalampaa kuin ~5 m — kasvillisuutta ja saaliskalaa rannasta rantaan. Päästä päähän vesi mittaa noin 14.3 km, leveimmillään 6 km. Lähin kartoitettu vesi on Hailuoto - Kuivaniemi - Sector 02, 11.3 km luoteeseen.

Occurrence evidence does not promise a catch or establish that retention is legal. Current seasons, closures, protected species, gear rules and local restrictions always control. The roster may combine exact-water monitoring with habitat-filtered official regional evidence; it does not imply that every species is equally abundant throughout the mapped section.

Spring puts european perch in skinny water — 1 to 3.5 m is the zone. As the season builds they drop to 1.5 to 5 m, wintering in 1.5 to 5 m. Spring european perch concentrate at Weed flat, a prime-rated weed flat around 2.5 m. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Weed flat (2.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 1.5 to 5 m | dawn | Deepest basin (5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 1.5 to 5 m | midday | Deepest basin (5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 1.5 to 5 m | midday & dawn | Deepest basin (5 m) | Tungsten jig + maggots, Small balance jig |
Spring puts northern pike in skinny water — 0.5 to 2.5 m is the zone. Warm water sends them out to 1.5 to 5 m; cold water stacks them in 1.5 to 4.5 m. Weed flat is the standout, a weed flat at roughly 2.5 m, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.

| Kevät | 0.5 to 2.5 m | midday & dawn | Weed flat (2.5 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 1.5 to 5 m | dawn & dusk | Weed flat (2.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 1.5 to 5 m | midday & dawn | Sharp break (3.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Weed flat (2.5 m) | Large jigging spoon |
In spring, atlantic herring run shallow here, mostly 1 to 5 m. Summer keeps them at 1.5 to 5 m, and they winter in 1.5 to 5 m. Deepest basin is the standout, a deep basin at roughly 5 m, rated prime for summer atlantic herring. Time it for early morning and the evening. You won't need more than a herring feather rig or a small silver jig most summer days.

|---|---|---|---|---|
| Kevät | 1 to 5 m | dawn & dusk | Rock reef (1 m) | Small herring feather rig, Micro jig rig |
| Kesä | 1.5 to 5 m | dawn & dusk | Deepest basin (5 m) | Herring feather rig, Small silver jig |
| Syksy | 1 to 5 m | dawn & dusk | Deepest basin (5 m) | Small feather rig, Compact silver spoon |
| Talvi | 1.5 to 5 m | midday | Deepest basin (5 m) | Small silver jig, Sparse feather rig |
Come spring, look for european whitefish tight to the bank in 1 to 5 m. Through summer count on 1.5 to 5 m; the winter hold is 1.5 to 5 m. Start at Deepest basin. It's a deep basin holding about 5 m of water and rates prime come spring. Prime time lands in early morning and the evening. A small vertical spoon or a micro jig is the honest summer answer here.

| Kevät | 1 to 5 m | dawn & dusk | Deepest basin (5 m) | Small silver spoon, Micro blade bait |

The spring pattern is a shallow one: sea trout in 1 to 5 m. The depth story barely changes: 1.5 to 5 m through summer, 1 to 5 m in winter. Top water on the chart: Rock reef, a rock pile in the 1 m range, prime in spring. Time it for early morning and the evening. Summer baits: a deep-running wobbler or a trolled spoon gets it done.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 5 m | dawn & dusk | Rock reef (1 m) | Slim coastal spoon, Shallow-running wobbler |
| Kesä | 1.5 to 5 m | dawn & dusk | Sharp break (3.5 m) | Deep-running wobbler, Trolled spoon |
| Syksy | 0.5 to 5 m | dawn & dusk | Shoreline point (1.5 m) | Coastal wobbler, Casting spoon |
| Talvi | 1 to 5 m | midday | Rock reef (1 m) | Slow coastal spoon, Suspending wobbler |
Early season european smelt use the shallows, holding in 0.5 to 5 m. Even in summer they hold at 1.5 to 5 m; winter keeps them in 1.5 to 5 m. The chart's best answer is Deepest basin — deep basin, 5 m, prime for summer. Best bite is early morning and the evening. Tie on a tiny vertical spoon or a micro jig and you're in the game.

No active municipality-, consortium-, or state-owned LIPAS fishing, boating, beach, swimming, canoe or motor-boat facility matched within 400 metres of this exact mapped shoreline. This is an access-evidence gap, not a claim that public access does not exist. Verify land ownership, local signs, parking, safety, permits and fishing permission before entry.
Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for Finland waters are set by the Kalastusrajoitus.fi (official current Finnish fishing-restriction service) — and special regulations can apply to Ii - Olhava - Taipale - North specifically, so confirm the current rules before you fish. Check Kalastusrajoitus.fi, current protection periods and permit requirements before every Finnish coastal trip. Local no-fishing areas, river-mouth restrictions, protected species, minimum sizes, seasonal closures, gear rules, the fisheries-management fee and water-owner permissions may apply. A mapped hydrographic contour, fishing-spot marker or nearby LIPAS public facility is planning context only and never grants fishing, retention, shoreline entry, parking, launching or safe-navigation permission.
