Fisustaja

Fisustaja shows on a map where Finland's most promising rivers and streams are – and whether it's worth heading out right now.

The app scores every river and stream in Finland (over 42,000 waterways) based on open geospatial data. The score combines four things anglers care about:

• Migratory fish waters – the authorities' assessment of where salmonids move
• Rapids – mapped rapids and fast-flowing stretches
• River size – based on catchment area; wadeable rivers score best, not huge main channels or tiny brooks
• Ecological status of waters – healthy waters correlate with good trout streams

Results appear on the map in traffic-light colors: green is promising, yellow moderate, red poor. Tap a waterway to see the score breakdown.

FLOW AND TIMING

Flow rate determines whether a rapid is fishable. Fisustaja shows the latest flow reading from SYKE's monitoring stations, tells you whether flow is rising or falling, and draws a 60-day history graph.

WATER TEMPERATURE

Temperature tells you when the fish are feeding. Fisustaja shows the latest surface water temperature from SYKE's stations as its own map layer, with a history graph as well.

Stations are sparse, so you can measure yourself: tap a river on the map and add your reading. Other anglers see it right away. Readings reported by anglers carry a thermometer with a small k in the corner – SYKE's official stations stay clearly their own.

Please note: the app does not show fishing restrictions or permit information. Always verify current restrictions and permits at kalastusrajoitus.fi and eraluvat.fi.

DATA SOURCES

The app is built on open data: the Finnish Environment Institute SYKE (waterway network, water status, flow and temperature, CC BY 4.0), the Ministry of Agriculture and Forestry and the ELY Centres (boundaries of migratory fish waters, used as scoring input), and OpenStreetMap contributors (base map and rapids). Fishing spot scores are the app's own computed estimate and do not guarantee a catch or a fishing right.

Tight lines and safe trips!
