281-acre lake in Finland. The lake tops out around 20 m. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
Kartalla Kotaselkä kattaa 113 hehtaaria, rantaviivaa 11.1 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 3) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 59% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 3.1 km, leveimmillään 0.8 km. Vesi sijaitsee alueella Ylä-Pirkanmaan seutukunta. Lähin kartoitettu vesi on Ajosjärvi, 4.8 km luoteeseen.

Spring puts european perch in skinny water — 1 to 3.5 m is the zone. As the season builds they drop to 2.5 to 8.5 m, wintering in 3.5 to 10 m. Spring european perch concentrate at Shallow bay flat, a prime-rated weed flat around 1 m. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Shallow bay flat (1 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Shallow bay flat (1 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 |
Spring puts northern pike in skinny water — 0.5 to 2.5 m is the zone. Warm water sends them out to 2.5 to 6 m; cold water stacks them in 1.5 to 4.5 m. Shallow bay flat is the standout, a weed flat at roughly 1 m, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Shallow bay flat (1 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Secondary point (2.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Main-lake point (2 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Shallow bay flat (1 m) | Tip-ups, Large jigging spoon |
Spring puts zander in skinny water — 1 to 4.5 m is the zone. As the season builds they drop to 4.5 to 11 m, wintering in 6 to 12 m. Fall zander concentrate at Secondary point, a prime-rated point around 2.5 m. Warm-month bites cluster around the evening and early morning. A vertical softbait over humps or a deep crankbait covers the summer program.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Main-lake point (2 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Secondary point (2.5 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Secondary point (2.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Break off the point (15 m) | Vertical jig / mormyshka with bait, Slow blade bait |
When the water first warms, lake whitefish slide up into 4.5 to 14 m. Summer is a 6 to 20 m game here, winter a 6 to 20 m one. Start at Deep basin. It's a deep basin holding about 20 m of water and rates prime come summer. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 4.5 to 14 m | midday & dawn | Break off the point (15 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 6 to 20 m chart-limited; documented 12 to 27 m | dawn | Deep basin (20 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Secondary point (2.5 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 6 to 20 m chart-limited; documented 7.5 to 21 m | midday & dawn | Deep basin (20 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: burbot sit in 6 to 20 m that time of year. They don't go far with the seasons — 6 to 20 m covers summer, 4.5 to 18 m covers winter. Top water on the chart: Deep basin, a deep basin in the 20 m range, prime in spring. Fish it in after dark and midday and you'll meet the bite. Throw a heavy jig + cut bait until the fish tell you otherwise.

Kotaselkä carries 6 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 20 m down.
Season dates, license requirements, and size and bag limits for Finland waters are set by the Kalastusrajoitus.fi (official Finnish restriction service) — and special regulations can apply to Kotaselkä specifically, so confirm the current rules before you fish.

Kotaselkä is about 66 ft (20 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.
Kotaselkä on syvimmillään noin 20 metriä (66 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Kotaselkä. 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.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for european perch in spring. Open the map above to see every rated spot for each species and season.
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.
