    Elevation profile of the watercourse

    How the watercourse falls downstream: fall, gradient and water speed.

    Very slow watercourse A lowland, almost stagnant section: calm, often more turbid water; the bottom tends to be muddy and sandy. Typical of carp fishing districts.

    Fall of the fishing districtsFallThe difference in altitude between the upper and lower end of the fishing district in metres. The greater the fall over a shorter length, the faster the water.

    Average gradientWatercourse gradientFall per kilometre in per mille (‰, metres per kilometre). Up to 2 ‰ is a slow lowland river, 5 to 10 ‰ a foothill river (grayling, trout), above 10 ‰ a fast stream.
    0,2 ‰
    SinuositySinuosityThe length of the watercourse divided by the straight-line distance between its ends. 1.0 is a straight watercourse; above 1.3 it meanders strongly. Meanders create pools under the banks and shallows in the reaches between.

    Groundwater: measured valuestypical value from stations within 10 km, 2025

    4 of 4 fishing districts with measurements have groundwater nearby with a value above the limit for at least one indicator.

    • nitrates above the standard (from 50 mg/l)1
    • harmful substances above the standard at at least one station (metals, pesticides, PFAS, solvents)4

    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.
