13,729-acre Olkijoki - Siikajoki - Säärenperä. 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 9 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 Olkijoki - Siikajoki - Säärenperä - North kattaa 5 556 hehtaaria, rantaviivaa 66.5 km, ja saaria on 86. Rantaviiva on voimakkaasti rikkonainen (indeksi 2.5) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 90% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 11.9 km, leveimmillään 9.3 km. Lähin kartoitettu vesi on Luodonselkä - West, 9.7 km koilliseen.

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.

In spring, european perch run shallow here, mostly 1 to 3.5 m. Summer pushes them deeper, 2.5 to 8.5 m, and winter fish settle into 2.5 to 9 m. Weed flat is the standout, a weed flat at roughly 2 m, rated prime for spring european perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small crankbait (perch pattern) most summer days.

| Kevät | 1 to 3.5 m | midday & dawn | Weed flat (2 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Sharp break (4.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |

| Talvi | 2.5 to 9 m | midday & dawn | Deepest basin (9 m) | Tungsten jig + maggots, Small balance jig |
In spring, northern pike run shallow here, mostly 0.5 to 2.5 m. Midsummer fish sit out in 2.5 to 6 m before dropping to 1.5 to 4.5 m for winter. Spring northern pike concentrate at Weed flat, a prime-rated weed flat around 2 m. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.

Spring puts atlantic herring in skinny water — 1.5 to 7.5 m is the zone. As the season builds they drop to 2.5 to 9 m, wintering in 2.5 to 9 m. Summer atlantic herring concentrate at Deepest basin, a prime-rated deep basin around 9 m. Warm-month bites cluster around early morning and the evening. A herring feather rig or a small silver jig covers the summer program.

When the water first warms, european whitefish slide up into 2.5 to 9 m. There's no big seasonal slide here — summer means 2.5 to 9 m, winter 2.5 to 9 m. If you only fish one area, make it Deepest basin: a deep basin around 9 m that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a small vertical spoon or a micro jig rigged through the warm months.

Start shallow in spring: sea trout sit in 1 to 6 m that time of year. Summer pushes them deeper, 2.5 to 9 m, and winter fish settle into 1.5 to 9 m. The spot to know is Sharp break, a drop-off in about 9 m of water that rates prime for sea trout in summer. Warm-month bites cluster around early morning and the evening. Throw a deep-running wobbler or a trolled spoon until the fish tell you otherwise.

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 Olkijoki - Siikajoki - Säärenperä - 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.
