34-acre lake in Finland. The lake tops out around 3 m. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
Vesi piirtyy 14 hehtaarin laajuisena, rantaa 4.7 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 3.6) — 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 1.6 km, leveimmillään 0.3 km. Vesi sijaitsee alueella Kehys-Kainuun seutukunta. Lähin kartoitettu vesi on Harjajärvi, 0 km koilliseen.

Come spring, look for european perch tight to the bank in 1 to 3 m. Through summer count on 1 to 3 m; the winter hold is 1 to 3 m. If you only fish one area, make it Deep basin: a deep basin around 2.5 m that scores prime in fall. 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 m chart-limited; documented 1 to 3.5 m | midday & dawn | Shallow bay flat (0.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 1 to 3 m chart-limited; documented 2.5 to 8.5 m | dawn | Deep basin (2.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 1 to 3 m chart-limited; documented 3 to 10 m | midday | Deep basin (2.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 1 to 3 m chart-limited; documented 3.5 to 10 m | midday & dawn | Deep basin (2.5 m) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 0.5 to 2.5 m. Summer is a 1 to 3 m game here, winter a 1 to 3 m one. The chart's best answer is Shallow bay flat — weed flat, 0.5 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 | Shallow bay flat (0.5 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 1 to 3 m chart-limited; documented 2.5 to 6 m | dawn & dusk | Break off the point (1.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 1 to 3 m chart-limited; documented 2 to 5.5 m | midday & dawn | Break off the point (1.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1 to 3 m chart-limited; documented 1.5 to 4.5 m | midday | Shallow bay flat (0.5 m) | Tip-ups, Large jigging spoon |
In spring, lake whitefish run shallow here, mostly 1 to 3 m. Summer keeps them at 1 to 3 m, and they winter in 1 to 3 m. Deep basin is the standout, a deep basin at roughly 2.5 m, rated prime for summer lake whitefish. Time it for early morning. You won't need more than a blade bait vertical or a small jigging spoon most summer days.

Spring burbot on Harjusalmi hold shallow, usually 1 to 3 m. Depth-wise the year is flat: 1 to 3 m in summer, 1 to 3 m once it turns cold. The chart's best answer is Deep basin — deep basin, 2.5 m, prime for spring. Prime time lands in after dark and midday. The summer box starts with a heavy jig + cut bait.

Harjusalmi is about 10 ft (3 m) deep at its deepest point. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Harjusalmi on syvimmillään noin 3 metriä (10 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, lake whitefish, burbot on Harjusalmi. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
Deep basin is the top-rated area: a deep basin in about 9 ft of water that rates prime for european perch in fall. Every other rated spot, per species and season, is on the map above.
For european perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Harjusalmi is regulated by the Kalastusrajoitus.fi (official Finnish restriction service). Check the official Finland regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
