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.

    What lies beneath the water and around it? An overview in tiles, a map of mine workings, deposits, environmental burdens, boreholes and gold finds, and how to read the data

    The overview is based on public registers and atlases of the State Geological Institute of Dionýz Štúr. The search covers a zone around the water of all fishing districts of the stream (6 km of line in total): stream samples within 1 km, boreholes, mine workings and burdens within 3 km, ore occurrences within 5 km, geothermal sources within 10 km.

    The line is the water of the fishing district, the light band is the 3 km zone in which boreholes, mine workings and burdens were searched for. The map shows the nearest objects (at most a few dozen from each register), not all of them. The points correspond to the position in the register; area objects are marked by their centre.

    How to read these data

    • Zone and distance. The distance is measured from the line of the water to the point in the register (to the centre for areas), with an accuracy of tens of metres. Counts apply only to the zone, not to the whole catchment.
    • Percentile. For chemistry, the highest value is compared with all atlas samples in Slovakia. It is not a legal limit or a health risk assessment; the atlases are historical (published: surface waters 2015, groundwater 1996, river sediments 1999).
    • Limit of quantification. Many samples have a value at the lowest level the laboratory can determine; such results mean "below the limit". For these, the position in the distribution is an estimate.
    • Panning concentrates. Only samples with a find are recorded. The number of grains in a concentrate is not the gold content in grams per tonne.
    • Relation to water. A mine working, landfill or burden nearby proves nothing about the quality of the water in the stream. It serves as a prompt for attention and a starting point for further investigation.
    • Sample points. The area and raster maps of ŠGÚDŠ cannot be downloaded as points, so along the line of each fishing district the value is looked up at points roughly every 3 km. It is a sample of the line, not a continuous record; a very short section may have a single point.
    • Atlas rasters. The chemistry of water and sediments is an interpolation of measurements in a sampling network (Geochemical Atlas of Slovakia). The value at a point is a modelled estimate for the surroundings, not a measurement in the water. The percentile compares the average of this stream with all sample points on streams in Slovakia.
    • Positions and scales. The maps have different scales (1:50,000 to 1:1,000,000), so the level of detail differs between sections. A map outside its coverage means there is no area at that point, not that there is nothing there.

    Geological structure beneath the water

    Which rock lies beneath the water line (Geological Map of Slovakia 1:50,000), how old it is, how thick the Quaternary cover is and in which tectonic unit the water flows. The bedrock decides the hardness of the water, the bottom, the turbidity after rain and the abundance of springs.

    The points follow the water line (for a stream and a basin, fishing district after fishing district). The strip is a cross-section by distance, not a map; the width of a section corresponds to the number of points.

    Hydrogeology: aquifers and groundwater

    Streams and rivers are fed by groundwater. Hydrogeological maps show in which rocks the water is stored, how permeable they are and what the water in them is like. The data come from ŠGÚDŠ maps, not from measurements at a particular water.

    Geophysical fields: magnetics and gravity

    Maps of the magnetic field and gravity (ŠGÚDŠ) reveal what lies beneath the sediments and the surface: volcanic bodies, faults and crustal thickness. For an angler they are interesting indirectly: they show where the bedrock changes, and with it the water.

    SVJZ

    Magnetic anomaly

    -55nT

    range -59 to -51 nT

    Deviation of the Earth's magnetic field from its surroundings. Positive and negative anomalies reveal rocks with magnetite (basalts, basic volcanic rocks) and boundaries in the bedrock.

    Bouguer gravity anomaly

    -33mGal

    residual −0.7 mGal

    Negative values lie over thick sediments and under mountains (light crust), positive over dense rocks and thinner crust. It shows the structure of the Earth's crust, not the water.

    Chemistry of water and river sediments

    What is in the water and on the bed? Trace elements and metals, nutrients, major ions, elements in sediments and groundwater

    Surface water chemistry according to the atlas

    Modelled composition of the water in the area the fishing district line runs through. The rasters of the Geochemical Atlas of Slovakia (surface waters) are an interpolation of measurements in sampled streams, so they show the typical background of the area, not a measurement in a particular stream.

    Water acidity

    pH 8.38typical range

    Most rivers and streams in Slovakia have a pH of 6.5 to 8.5. More acidic water is found in streams on acidic rocks (granites, quartzites), more alkaline water near limestones.

    Water hardness

    16.5°dH, hard

    Sum of calcium and magnesium (2.95 mmol/l). Hard water is buffered and its pH changes more slowly; soft water is more sensitive to acid rain.

    Dissolved substances

    463mg/l mineralisation

    Total amount of dissolved minerals. Clean mountain water has tens of mg/l, lowland and limestone waters hundreds.

    Ionic composition of the water

    Airborne gamma-ray spectrometry by ŠGÚDŠ measures radiation from potassium, uranium and thorium in rocks and soil. Granites and some acidic volcanic rocks have the highest values, limestones and floodplains the lowest. Caesium-137 is a remnant of fallout from the Chernobyl accident and nuclear weapons tests.

    Radon risk of the bedrock

    low

    Radon is a natural gas from rocks. The risk concerns buildings and cellars, not the water in the stream; it shows what the bedrock is like.

    Environmental burdens, landfills and landslides

    What in the surroundings can harm the water? Environmental burdens, waste landfills, anthropogenic sediments and slope deformations    Burdens and landfills1

    Environmental burdens, landfills and anthropogenic sediments

    Recorded environmental burdens (industrial sites, landfills, mining), the register of waste landfills and monitoring of anthropogenic sediments (industrial sludge). It is a list of places, not a measurement of water pollution.
