21,945-acre Korppoon - Houtskarin ulkosaaristoalue. 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 Archipelago 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 51 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 8 878 hehtaarin laajuisena, rantaa 128.1 km, ja saaria on 209. Rantaviiva on voimakkaasti rikkonainen (indeksi 3.8) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 13% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 16.9 km, leveimmillään 11.1 km. Lähin kartoitettu vesi on Skiftet Södra - North, 8 km länteen.

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.

Come spring, look for european perch tight to the bank in 1 to 3.5 m. They move out to 2.5 to 8.5 m in summer and finish the year down in 3.5 to 10 m. If you only fish one area, make it Weed flat: a weed flat around 1.5 m that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Weed flat (1.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Weed flat (2.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | open water | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | open water | Tungsten jig + maggots, Small balance jig |
Come spring, look for zander tight to the bank in 1 to 4.5 m. They move out to 4.5 to 11 m in summer and finish the year down in 6 to 12 m. If you only fish one area, make it Rock reef: a rock pile around 2.5 m that scores good in spring. Best bite is the evening and early morning. A vertical softbait over humps or a deep crankbait is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Rock reef (2.5 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Shoreline point (4.5 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Shoreline point (4.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | open water | Slow blade bait |
Early season northern pike use the shallows, holding in 0.5 to 2.5 m. Summer is a 2.5 to 6 m game here, winter a 1.5 to 4.5 m one. The chart's best answer is Weed flat — weed flat, 1.5 m, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Weed flat (1.5 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Weed flat (2.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Weed flat (2.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Weed flat (1.5 m) | Large jigging spoon |
When the water first warms, atlantic herring slide up into 1.5 to 7.5 m. Summer is a 4.5 to 15 m game here, winter a 6 to 18 m one. Start at Sharp break. It's a drop-off holding about 14 m of water and rates good come summer. The feeding windows run early morning and the evening. Keep a herring feather rig or a small silver jig rigged through the warm months.

| Kevät | 1.5 to 7.5 m | dawn & dusk | Rock reef (2.5 m) | Small herring feather rig, Micro jig rig |

| Talvi | 6 to 18 m | midday | Sharp break (14 m) | Small silver jig, Sparse feather rig |
Start shallow in spring: european whitefish sit in 3 to 12 m that time of year. Summer pushes them deeper, 8.5 to 24 m, and winter fish settle into 5.5 to 18 m. The spot to know is Sharp break, a drop-off in about 14 m of water that rates good for european whitefish in summer. Warm-month bites cluster around early morning and the evening. Throw a small vertical spoon or a micro jig until the fish tell you otherwise.

The spring pattern is a shallow one: european flounder in 1.5 to 7.5 m. Midsummer fish sit out in 2 to 11 m before dropping to 4.5 to 15 m for winter. The spot to know is Sharp break, a drop-off in about 14 m of water that rates good for european flounder in winter. Plan around early morning and the evening in the warm months. Summer baits: a bottom jig with spinner blade 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 Korppoon - Houtskarin ulkosaaristoalue - 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.
