Map of the corridor
Where the nearest mine workings, deposits, burdens, geothermal boreholes and gold finds are. Groups can be switched off.
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 center.
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 center for areas), with an accuracy of tens of meters. 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 modeled 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.
What does the water flow over? Geological structure and age of the rocks, groundwater aquifers, relief, climate, soils and geophysical fields
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.

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.
Magnetic anomaly
+8nT
range -49 to 50 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.

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
Modeled 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 8.32typical 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
12.5°dH, moderately hard
Sum of calcium and magnesium (2.23 mmol/l). Hard water is buffered and its pH changes more slowly; soft water is more sensitive to acid rain.

Sediment collects metals from rocks, ore occurrences and past mining and industry. It is not a legal limit or a health risk assessment: it shows how an element on this stream ranks among streams in Slovakia.

Gold and ore minerals in river sediments
Regional panning prospecting: the heavy fraction was washed out of river gravel and the mineral grains in it were counted. The map of finds is positive: a sample without gold is not listed in the atlas, so the absence of a find is not proof that there is no gold.

Is there heat underground? Geothermal potential, geothermal boreholes by temperature, mineral springs and the borehole archiveHottest borehole29 °CBoreholes1 455
Geothermal potential
The Atlas of Geothermal Energy of Slovakia records rock temperature and heat flow from the Earth's interior. It is the potential of the area, not the actual warmth of the water in the stream. Specific geothermal boreholes and springs near this water are in the geothermal energy section below.
Rock temperature with depth
45 / 65 °Cat depths of 1,000 and 2,000 m
increase of 20 °C per km
The line shows the rock temperature; the dotted part is only an extension to the surface. Heat flow 70 mW/m².
Geothermal energy and mineral waters
Geothermal boreholes (wellhead water temperature, yield, chemical type) and sources of geothermal and mineral waters within 10 km. Data on the use and existence of a borehole come from the Geofond register.

Boreholes and Geofond archive reports
Register of hydrogeological boreholes, other boreholes and geothermal boreholes. Each borehole has a report in the Geofond archive (geological profiles, pumping tests, chemical analyzes of the water); the report number is in the table.
1,455 boreholes in the 3 km zone, of which 82 hydrogeological and 1373 other; with an archive report number 1455.
How much does the ground radiate here? Gamma radiation of rocks, radon in soil and radon in waters
Natural radioactivity and radon
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.
Gamma radiation dose rate
43nGy/h in air
range 24 to 72 nGy/h
Natural background from rocks and soil; higher over granites and some acidic volcanic rocks, lower over limestones and floodplains.

Radon risk of the bedrock

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.
