What a recipe is
A recipe is a ready-made combination of map filters. It combines two to four data points (geology, oxygen, nutrients, depth, water suitability for the district type), the water type and the location, and shows the fishing districts where everything matches. For each one you see the number of matching fishing districts; clicking opens the map with the filter set, which you can adjust.
Recipes are ideas for searching, not a recommendation of where to fish. They improve along with the data: if a recipe has no fishing districts, it is not shown on the page.
Recipe of the week: Limestone trout
Trout waters where limestone or dolomite is the main rock along the water.

Move the map with two fingers. In full-screen mode one finger is enough.
The score is an estimate of conditions based on weather, water and surroundings, not a bite forecast. For each fishing district you can see what it is made of, how well it is supported by data and where the data comes from.
43 fishing districts match this recipe. The recipe changes every week.

Where the data come from and what they do not say
The data come from files of the State Geological Institute of Dionýz Štúr (ŠGÚDŠ):
- Geochemical Atlas of the Slovak Republic: surface waters, concentration rasters (ŠGÚDŠ)
- Geological map of the Slovak Republic 1 : 50,000 (ŠGÚDŠ)
What this data does not tell you. The atlas values are historical maps and model estimates, not measurements in the water. We assign them to a fishing district according to points along the water line (within a radius of 1 to 3 km, 10 km for springs). Neighboring districts share the same points, so the data repeat along streams. The ranking is indicative and is not an assessment of water quality or of the safety of fish. A district without a record does not necessarily have nothing there; it may mean that nobody has looked.
Water quality in a stream is assessed by the SHMÚ yearbooks, see The cleanest water in Slovakia.
