1,525-acre lake in Finland. The lake tops out around 25 m. The depth chart comes from Finnish Environment Institute (Syke) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Kartalla Renkajärvi kattaa 622 hehtaaria, rantaviivaa 30.7 km. Rantaviiva on voimakkaasti rikkonainen (indeksi 3.5) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 59% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 8.2 km, leveimmillään 1.6 km. Vesi sijaitsee alueella Hämeenlinnan seutukunta. Lähin kartoitettu vesi on Takajärvi, 6.4 km koilliseen.

Spring puts european perch in skinny water — 1 to 3.5 m is the zone. Warm water sends them out to 2.5 to 8.5 m; cold water stacks them in 3.5 to 10 m. Shallow bay flat is the standout, a weed flat at roughly 1 m, rated prime for spring european perch. Plan around early morning in the warm months. 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 | Break off the point (8 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Break off the point (8 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Break off the point (8 m) | Tungsten jig + maggots, Small balance jig |
Spring puts northern pike in skinny water — 0.5 to 2.5 m is the zone. As the season builds they drop to 2.5 to 6 m, wintering in 1.5 to 4.5 m. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 1 m. Warm-month bites cluster around early morning and the evening. 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 | Shallow feeding flat (6.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Back-bay flat (1.5 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Back-bay flat (1.5 m) | Tip-ups, Large jigging spoon |
Spring puts zander in skinny water — 1 to 4.5 m is the zone. Warm water sends them out to 4.5 to 11 m; cold water stacks them in 6 to 12 m. Break off the point is the standout, a drop-off at roughly 8 m, rated prime for fall zander. Plan around the evening and early morning in the warm months. 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 | Secondary point (1 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Break off the point (8 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Break off the point (8 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Break off the point (8 m) | Vertical jig / mormyshka with bait, Slow blade bait |
When the water first warms, lake whitefish slide up into 4.5 to 14 m. By summer they slide out to 7.5 to 25 m, and by winter most fish are in 7.5 to 21 m. If you only fish one area, make it Deep basin: a deep basin around 24 m that scores prime in summer. In summer the feeding windows fall in 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 (8 m) | Small jig + waxworm, Blade bait (small) |
| Kesä | 7.5 to 25 m chart-limited; documented 12 to 27 m | dawn | Deep basin (24 m) | Blade bait vertical, Small jigging spoon |
| Syksy | 2.5 to 9 m | dusk | Break off the point (8 m) | Small spoon (gold), Jig + plastic larva |
| Talvi | 7.5 to 21 m | midday & dawn | Deep basin (24 m) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: burbot sit in 7.5 to 21 m that time of year. Summer pushes them deeper, 7.5 to 25 m, and winter fish settle into 4.5 to 18 m. The spot to know is Deep basin, a deep basin in about 24 m of water that rates prime for burbot in summer. Warm-month bites cluster around after dark and midday. Throw a heavy jig + cut bait until the fish tell you otherwise.

Renkajärvi is about 82 ft (25 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.
Renkajärvi on syvimmillään noin 25 metriä (82 jalkaa). Syvyydet perustuvat todellisiin luotauksiin.
Anglers target european perch, northern pike, zander, lake whitefish, burbot on Renkajärvi. 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. Scroll up to the map for the complete spot list by 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.
