5,677-acre Korsnäs-Kaldonskär. Sector 05 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 23 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. Every species below gets its seasonal read from the same numbers driving the chart.
Vesi piirtyy 2 297 hehtaarin laajuisena, rantaa 28.6 km. Rantaviiva on kohtalaisen rikkonainen (indeksi 1.7). Noin 2% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 12.4 km, leveimmillään 3.7 km. Lähin kartoitettu vesi on Korsnäs-Kaldonskär - Sector 06, 6.4 km kaakkoon.

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.

Early season european perch use the shallows, holding in 1 to 3.5 m. Expect a summer slide to 2.5 to 8.5 m, then a winter hold in 3.5 to 10 m. Put Sharp break first on the milk run — a drop-off near 6.5 m that grades good for summer. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small crankbait (perch pattern) and you're in the game.
| 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 (6.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Sharp break (6.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Sharp break (6.5 m) | Tungsten jig + maggots, Small balance jig |
Come spring, look for northern pike tight to the bank in 0.5 to 2.5 m. Expect a summer slide to 2.5 to 6 m, then a winter hold in 1.5 to 4.5 m. Start at Sharp break. It's a drop-off holding about 6.5 m of water and rates good come summer. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

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

Spring atlantic herring on Korsnäs-Kaldonskär - Sector 05 hold shallow, usually 1.5 to 7.5 m. By summer they slide out to 4.5 to 15 m, and by winter most fish are in 6 to 18 m. The chart's best answer is Sharp break — drop-off, 6.5 m, good for summer. Prime time lands in early morning and the evening. The summer box starts with a herring feather rig or a small silver jig.

| Kevät | 1.5 to 7.5 m | dawn & dusk | open water | Small herring feather rig, Micro jig rig |

Spring puts european whitefish in skinny water — 3 to 12 m is the zone. Warm water sends them out to 6.5 to 23 m; cold water stacks them in 5.5 to 18 m. Deepest basin is the standout, a deep basin at roughly 22 m, rated prime for summer european whitefish. Plan around early morning and the evening in the warm months. A small vertical spoon or a micro jig covers the summer program.

| Kevät | 3 to 12 m | dawn & dusk | Sharp break (6.5 m) | Small silver spoon, Micro blade bait |

Early season sea trout use the shallows, holding in 1 to 6 m. Summer is a 4.5 to 15 m game here, winter a 1.5 to 9 m one. The chart's best answer is Sharp break — drop-off, 6.5 m, prime for summer. Best bite is early morning and the evening. Tie on a deep-running wobbler or a trolled spoon and you're in the game.

|---|---|---|---|---|
| Kevät | 1 to 6 m | dawn & dusk | open water | Slim coastal spoon, Shallow-running wobbler |

| Talvi | 1.5 to 9 m | midday | Sharp break (6.5 m) | Slow coastal spoon, Suspending wobbler |
The spring pattern is a shallow one: european smelt in 1 to 7.5 m. As the season builds they drop to 7.5 to 21 m, wintering in 6 to 20 m. Top water on the chart: Deepest basin, a deep basin in the 22 m range, good in summer. Time it for early morning and the evening. Summer baits: a tiny vertical spoon or a micro jig gets it done.

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 05 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.
