Where to Fish?

The data behind the map

Where do the waters and fish data come from?

Where to Fish? brings together geographic water records, public datasets and fishing information. Each source answers a different question, and coverage varies around the world.

What these numbers mean

These are counts of examined local files, not verified fishing spots, unique waters across all datasets or confirmed access points. Datasets can overlap. The GeoNames file includes waters under country and territory codes; it does not prove equal coverage everywhere.

Three levels of evidence

Geographic records help name and locate a lake, river or coastline. A point can sit in the middle of a water body and is not a place where fishing is allowed.

Documented fish information may come from a local authority or association. Scientific station observations have a location and date; they should not be treated as a current survey of an entire water body.

Other information in the app can be an estimate based on water type, country or general context. An estimate is not a local measurement or a guarantee of fish presence.
