24,035-acre Korsnäs-Kaldonskär. Sector 01 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 Sea. 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 18 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. The season-by-season read for each species follows, from the map's own numbers.
Vesi piirtyy 9 715 hehtaarin laajuisena, rantaa 46.5 km. Allas on yksinkertainen (rantaindeksi 1.3) — lähes malja, joten syvyyskäyrät merkitsevät enemmän kuin ranta. Noin 2% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 19.8 km, leveimmillään 9.5 km. Lähin kartoitettu vesi on Utgrynnan-Molpehällorna - Sector 07, 6.4 km pohjoiseen.

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 european perch on Korsnäs-Kaldonskär - Sector 01 hold shallow, usually 1 to 3.5 m. By summer they slide out to 2.5 to 8.5 m, and by winter most fish are in 3.5 to 10 m. The chart's best answer is Sharp break — drop-off, 8 m, good for summer. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small crankbait (perch pattern).
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | open water | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Sharp break (8 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Sharp break (8 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Offshore hump (8 m) | Tungsten jig + maggots, Small balance jig |
When the water first warms, northern pike slide up into 0.5 to 2.5 m. By summer they slide out to 2.5 to 6 m, and by winter most fish are in 1.5 to 4.5 m. If you only fish one area, make it Shoreline point: a point around 5 m that scores good in fall. In summer the feeding windows fall in early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

| Kevät | 0.5 to 2.5 m | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |

Early season atlantic herring use the shallows, holding in 1.5 to 7.5 m. Expect a summer slide to 4.5 to 15 m, then a winter hold in 6 to 18 m. Put Deepest basin first on the milk run — a deep basin near 18 m that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a herring feather rig or a small silver jig and you're in the game.

In spring, european whitefish run shallow here, mostly 3 to 12 m. Midsummer fish sit out in 5.5 to 18 m before dropping to 5.5 to 18 m for winter. Summer european whitefish concentrate at Deepest basin, a prime-rated deep basin around 18 m. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small vertical spoon or a micro jig most summer days.

Spring sea trout on Korsnäs-Kaldonskär - Sector 01 hold shallow, usually 1 to 6 m. They move out to 4.5 to 15 m in summer and finish the year down in 1.5 to 9 m. Put Rock reef first on the milk run — a rock pile near 3.5 m that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a deep-running wobbler or a trolled spoon.

Start shallow in spring: european smelt sit in 1 to 7.5 m that time of year. Summer pushes them deeper, 5.5 to 18 m, and winter fish settle into 5.5 to 18 m. The spot to know is Deepest basin, a deep basin in about 18 m of water that rates prime for european smelt in summer. Warm-month bites cluster around early morning and the evening. Throw a tiny vertical spoon or a micro jig until the fish tell you otherwise.

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 Korsnäs-Kaldonskär - Sector 01 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.
