All watercourses of the river basin

Cards with photos, search and detailed filters. You'll find the fishing districts on each watercourse's page.

Detailed filtersdepth, bottom, watercourse line, shading, vegetation, structures
DepthDepthThe greatest depth from the fishing district description. Shallows warm up quickly and are rich in food; deep pools give shelter and a more stable temperature.
BottomBottomThe bottom material determines which fish live here and where they find food. Fish zones can be recognized by the bottom: rocky, gravelly, sandy to muddy.you can select more than one
Watercourse lineWatercourse lineThe shape of the watercourse seen from above. In bends there is a deep scour under the outer bank and a shallow bar under the inner one; a winding stream has more shelter and changes in depth.you can select more than one
ShadingShadingThe share of the water surface in shade. Shade lowers summer water temperatures and supplies insects and shelter; a sunny section warms up faster and becomes more overgrown.
VegetationVegetationTree and herbaceous vegetation on the banks. Roots and branches create shelter, and leaves and twigs falling in provide food. It also determines where you can cast and where your rig gets snagged.you can select more than one
Cross-channel structuresCross-channel structuresWeirs, steps and dams hold back water and stop fish from migrating. Below them a deep plunge pool with oxygenated water forms.

For watercourses it is enough if at least one fishing district on the watercourse has the given property. Within one group the values complement each other (or); the groups combine (and).

    Source: SHMÚ (yearbooks on surface and groundwater quality), the register of wastewater treatment plants from VÚVH and the EEA. A SHMÚ site is assigned to a fishing district by the same watercourse name and by distance; the yearbook lists the sites that failed the standard, so a missing site is not proof of clean water.
