Fishing conditions score, the best window of the day and fishing districts from the best conditions Low activity · average of one fishing district 06:00–08:00 VN Považská Teplá, window score 24. The score is an estimate of conditions based on weather, water and surroundings, not a bite forecast. Recalculated at 09:04. The course of the watercourse and its fishing districts. You can switch the line color to today's conditions, quality or any other parameter. Detailed filtersregion, district, riverbed, depth, shading, satellites, water chemistry and pollution, fish, geology 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. Terrain height along the fishing district and the approximate water level. Reservoir This is a reservoir, so the watercourse is not assessed here: the water has no current, fall or gradient. The chart shows the terrain height along the fishing district. Source: Open Topo Data (eudem25m), 4 Nov 2026. The height is approximate (error of a few metres). Loading the 3D terrain model… Changes in the surroundings and nature from 2018 to 2024: how the banks, vegetation and landscape around the water change.

The year and day of imaging depend on the location, so individual years may differ in season and weather. Water quality according to SHMÚ, wastewater treatment plants near the fishing districts and groundwater nearby 0 of 1 fishing district with measurements has groundwater nearby with a value above the limit for at least one indicator. 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. Metals and gold in river sediments and water, old mine workings and deposits, boreholes with archive reports, geothermal energy, environmental burdens and landslides around the stream 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 (2 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. River alluvium100% of the water line Gravelly and sandy bottom and floodplains; the water is replenished from groundwater in the alluvium.

A landslide into a stream can cloud the water and change the bed. 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. marker on the bar: share among all sample points on streams in Slovakia River alluvium: Gravelly and sandy bottom and floodplains; the water is replenished from groundwater in the alluvium. marker on the bar: share among all sample points on streams in Slovakia marker on the bar: share among all sample points on streams in Slovakia marker on the bar: share among all sample points on streams in Slovakia marker on the bar: share among all sample points on streams in Slovakia marker on the bar: share among all sample points on streams in Slovakia marker on the bar: share among all sample points on streams in Slovakia marker on the bar: share among all sample points on streams in Slovakia marker on the bar: share among all sample points on streams in Slovakia marker on the bar: share among all sample points on streams in Slovakia The map covers 2 of 2 points on the water line. 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. marker on the bar: share among all sample points on streams in Slovakia marker on the bar: share among all sample points on streams in Slovakia 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. pH 8.13typical 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. 15.8°dH, hard Sum of calcium and magnesium (2.82 mmol/l). Hard water is buffered and its pH changes more slowly; soft water is more sensitive to acid rain. 458mg/l mineralisation Total amount of dissolved minerals. Clean mountain water has tens of mg/l, lowland and limestone waters hundreds. Water type by dominant ions: Ca–Mg–HCO₃ Shares are in equivalents, the usual way of comparing the composition of waters. dot: average along the water line, line: from the lowest to the highest value, scale: position among sample points on streams in Slovakia (0 to 100th percentile) The Geochemical Atlas of Slovakia (river sediments) describes what the river carries in the fine material on its bed. 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. dot: average along the water line, line: from the lowest to the highest value, scale: position among sample points on streams in Slovakia (0 to 100th percentile) 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. 50nGy/h in air range 49 to 50 nGy/h Natural background from rocks and soil; higher over granites and some acidic volcanic rocks, lower over limestones and floodplains. medium Radon is a natural gas from rocks.

For an angler they are interesting indirectly: they show where the bedrock changes, and with it the water. +18nT range 17 to 19 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. -47mGal residual −6.8 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. 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. 35 / 55 °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 55 mW/m². A basin is not just water: slope and elevation determine the speed of runoff, climate the temperature and amount of water, and soils what is washed into the stream. The data come from the geomorphological division, climatic-geographical types and soil maps of ŠGÚDŠ. marker on the bar: share among all sample points on streams in Slovakia marker on the bar: share among all sample points on streams in Slovakia 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 centre. Arsenic, antimony, cadmium, lead, copper, zinc and other elements in samples from rivers and streams (Geochemical Atlas of Slovakia, surface waters, 2015).
