Fishing district boundaries: Vodná plocha nádrže pri obci Kokošovce. VN Sigord is salmonid (trout) fishing district no. 4-3780-4-1. It lies in Prešov district (Prešov Region). According to the bed model, the surface at full level covers 4.5 ha and the greatest depth is 9.0 m. The fishing district is managed by SRZ organization Prešov Game fish of the fishing district (1): The bite score for fishing district VN Sigord is calculated for 4 game fish species from the weather right at the water, water temperature, light and air pressure. The forecast applies to the location 48.950° N, 21.354° E. The score, the best window of the day and what pushes it up or down Loading data… Hour by hour, pressure and the next few days Loading data… Where the sun and moon are right now and when the best windows of the day will come Drag along the axis to see where the sun and moon will be. The day lasts 9 h 13 min. Full moon around 24 Nov, new moon around 9 Dec. Solunar theory is not scientifically confirmed; we treat it as a supplement. The golden hour is the time around sunrise and sunset, when fish often bite. Fishing district VN Sigord is classed as salmonid (trout) waters. Permits for fishing district VN Sigord are issued by SRZ organization Prešov Closed season, fishing hours, minimum sizes and daily limit. For guidance only: check them in the fishing regulations of the fishing district 1 Oct – 15 Apr fishing for all fish prohibitedoutside this period Exception: on waters where huchen occurs, from 1 Nov to 31 Dec fishing for huchen is possible only with a huchen fishing permit (§ 13, para. 4 and § 19 of the Act). The protection periods by species (below) apply independently of this closed season. Applies only outside the closed season. Outside these hours fishing is prohibited (§ 14(b) of the Act). April, September6.00 – 20.00 h May, August5.00 – 21.00 h Jun, Jul4.00 – 22.00 h November, December7.00 – 19.00 h Months missing from the table fall within the closed season. The hours in November and December on trout and grayling waters relate to the exception for fishing huchen (§ 13, para. 4 of the Act); check in the fishing regulations what may be caught at that time. On border waters the hours in the permit or the fishing regulations apply (§ 11, para. 2 of the Decree). The Act regulates night fishing in two wordings that seem to contradict each other at first sight, so always ask about it in the fishing regulations of the fishing district or the fishing guard. This is a summary. For baits, hooks and groundbait also read the fishing regulations of the fishing district, because the user may tighten the conditions. The blue and green groups cannot be combined. The limit applies per day, also when fishing in several fishing districts, and once it is reached, fishing for that day ends. The species groups follow the SRZ interpretation of January 2026, not the text of the section directly. The fishing district user may set a lower limit in the permit, in which case the stricter one applies. During this period the species must not be caught, even if the water type otherwise allows fishing at that time. It applies independently of the closed season for all fish. Some species are protected all year round (for example zingel and streber, lampreys, gudgeons, spined loaches, maraena whitefish, Carpathian barbel, sabre carp) and fishing for them is always prohibited. The full list of species is in the guide The fishing law, rule by rule. The shortest length from which you may keep a fish. The fishing district user may raise the size, so look for the valid value in the permit and the fishing regulations. Total length is measured from the front of the head to the end of the longest ray of the tail fin (§ 12, para. 4). No minimum size applies, for example, to sunbleak, Prussian carp, European perch, roach, stone loach and invasive species. As of 6 Nov 2026: Act no. 216/2018 Coll. on fisheries (wording effective 1 Jan 2022) and Decree no. 381/2018 Coll. (wording effective 1 Jan 2019); we found no newer wording. The law may change; you can find the current wording on Slov-Lex (Act) and Slov-Lex (Decree).

Šariš č.1 – r.č. 4-2571-1-4 ZÁKAZ RYBOLOVU od 7:00 do 16:00 z dôvodu konania… The center of fishing district VN Sigord is at coordinates 48.94961, 21.35419. The fishing district is 363 m long. Course of the water, access, parking and spots marked by the organization The line shows the course of the fishing district according to the "Rybárske revíry" data 2026. Verify access points and exact boundaries on site. Where you can reach the water, where tributaries join and where there is danger Choose a fish species and the 3D model of the reservoir shows where it is most likely to be right now: by depth, bed, water temperature, light, season and time of day. The spots are an estimate from the environment, not the position of fish. Spots within 3 km of the watercourse are shown. Spots within 3 km of the watercourse are shown. 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. The height comes from a relief model and is approximate (error of a few meters). Loading the 3D terrain model… According to the bed model, fishing district VN Sigord has a greatest depth of 9.0 m and a mean depth of 3.2 m. At full level the surface covers 4.5 ha and the water volume is 0.14 million m³. The greatest depth comes from the fishing rules of the district. Loading the 3D model of the bed… Height is measured from the full level. The thicknesses of the bedrock layers are illustrative; the map shows the surface only. How the area and volume of water change as the level drops. Bed by zones of erosion and sediment deposition, bedrock from the geological map. The maximum depth is from the fishing regulations of the fishing district. The shape of the bed is a model, so it does not include holes or submerged objects. Moderately varied water How many different habitats the reservoir offers: drop-offs, shallows, depths, bed and old channels. A higher number means more places where fish hold, not more fish. What the bed and banks are made of: rock, sediments and their effect on the water After rain the water quickly turns turbid and fish hunt more by smell. According to the geological map: fluviálne sedimenty: litofaciálne nečlenené nivné hliny, alebo piesčité až štrkovité hliny dolinných nív a nív horských potokov, holocén The fishing district description states the bottom: sand; the geological map shows something different, and the fishing district description is more precise. The map shows the bedrock geology, not the exact bottom at the spot. The actual bottom material may differ, especially where sediment has been deposited. We record 1 game fish species in fishing district VN Sigord. Of these, 1 species is in the stocking plan. What is stocked into the fishing district and how much Suitability of the water for carp, trout and grayling species based on its properties The water is in the bottom 27% of 461 trout fishing districts with data. Reliability low: we used 4 water data points; the rest are missing and are not part of the assessment. ≈ 7.7 °dH (1.4 mmol/l of calcium and magnesium), ŠGÚDŠ atlas Moderately soft water: productivity is average. Water with calcium and magnesium is more productive and buffers acidity swings better: trout production was higher in calcareous hard waters (Almodóvar et al. 2006), and an index based on dissolved solids and depth predicts fish yield from lakes (Ryder et al. 1974). In Irish streams, however, geology did not change trout density (Lehane et al. 2004), and Downing et al. (1990) showed that production is related rather to primary production. Hence only ±1 point. Hardness comes from the ŠGÚDŠ atlas, not from a measurement in the fishing district; it replaces the separately assessed bedrock of the basin. Sources: Almodóvar et al. 2006; Lehane et al. 2004; Ryder et al. 1974 pH 7.9, ŠGÚDŠ atlas The pH is within the range in which fish commonly thrive. Below about pH 6 fish suffer, and trout and grayling are more sensitive than cyprinids (Alabaster and Lloyd 1982); in acidic soft water, aluminum is released from the soil and damages gills (Gensemer and Playle 1999). The pH from the atlas is a model estimate, so the reduction is only −1 or −2, and only where we have no pH measurement (which is assessed by a separate factor). Sources: Alabaster and Lloyd 1982; Gensemer and Playle 1999 ≈ 250 mg/l, ŠGÚDŠ atlas Medium mineralization corresponds to productive streams and reservoirs. Dissolved solids (mineralization) are related to the fertility of the water, which is why Ryder used them to estimate fish production in lakes (Ryder 1965, Ryder et al. 1974). Downing et al. (1990) showed, however, that primary production is a better predictor of production. It does not enter the score, only the suitability index. Sources: Ryder 1965; Ryder et al. 1974; Downing et al. 1990 2 elements among the highest 10% in Slovakia (ŠGÚDŠ atlas 1999) Metals in sediment can accumulate in benthic animals and fish; high values are often natural in ore areas. The toxicity of metals to fish decreases with water hardness, because calcium competes with the metal for sites on the gills (Pagenkopf 1983). The ŠGÚDŠ atlas gives only the rank among streams, not a concentration comparable with a limit (MacDonald et al. 2000). In hard water we therefore rate metals more leniently, in soft water more strictly. Sources: Pagenkopf 1983; Gensemer and Playle 1999; MacDonald et al. 2000 The same water data evaluated against the requirements of trout, grayling and carp. The fishing district is registered as a trout fishing district; its type is highlighted. The index 0 to 100 compares the properties of the water with the requirements of the species (60 is the neutral value, 100 the ideal). The verbal rating comes from comparison with other fishing districts of the same type, because most Slovak waters have good values for their species. The index does not affect whether fish really occur in the fishing district (that is decided by stocking and the manager). Hardness, pH and mineralization from the atlases are historical and model estimates. Only a small part of this feeds into the conditions score and fishing district quality (hardness ±1, atlas acidity −2 to 0, stream zone match ±1 to quality). What fish eat in this water and how to choose a bait or fly Few insects November: 0.0× the average month 0.0× the average month, 0 of 16 observations in the year, iNaturalist. The observations are added by people from the surrounding area; they are not measurements at the water. They show when aquatic insects usually appear and are useful mainly for fly fishing. Surface area, water clarity, algal bloom and ice at fishing district VN Sigord are tracked from Sentinel satellites. Water temperature is estimated from the weather at the water. Sentinel-2 (optical) and Sentinel-1 (radar), updated roughly every 6 days More turbid than usual (×1.6 compared with recent periods). Turbidity above 25 FNU is on 3% of the water surface. Since 30 Nov 2025: lowest 6 FNU (9 Apr 2026), highest 79 FNU (28 Feb 2026). An estimate based on the reflectance of the water in the red band. This is a relative aid, not a measurement in NTU. Sentinel-2, 11 Oct 2026, 81% of the area cloud-free Elevated chlorophyll shows on 41% of the water surface. Since 30 Nov 2025: lowest -0.10 (19 May 2026), highest 0.22 (6 Sep 2026). The NDCI index tracks chlorophyll-a in plant plankton (algae, cyanobacteria). It cannot determine the algae species or toxicity. Sentinel-2, 11 Oct 2026 The share of the area with green vegetation (plants on and just below the surface, reeds at the bank). Since 20 Nov 2025: lowest 3% (19 Jan 2026), highest 89% (3 Jul 2026). A strip of reeds at the banks may also be counted, so values on small areas may appear higher. Sentinel-2, 26 Oct 2026, 75% of the area cloud-free That is 0% of the usual maximum over the last year (3.2 ha). Since 20 Nov 2025: lowest 0.0 ha (19 Jan 2026), highest 3.9 ha (28 Feb 2026). Sentinel-1 radar (also sees through clouds and at night): 10% of the fishing district's shape is smooth water (4 Nov 2026), −3 pp over the month. The clear-water area excludes the pixels at the bank, so it is smaller than the area of the fishing district (28.0 ha according to the map). The change matters more than the number itself. In wind, radar may show the surface as rough. Sentinel-2, 26 Oct 2026, 75% of the area cloud-free The share of the area where the satellite sees ice or snow. Over the last 20 days the highest was 0%. The satellite cannot determine the thickness or load-bearing capacity of the ice. Never go onto the ice based on this figure. Sentinel-2, 26 Oct 2026, 75% of the area cloud-free Fish activity rises with the temperature. Fish hold in deeper, slower places. Since 8 Mar 2026: lowest 8.9 °C (8 Mar 2026), highest 27.7 °C (30 Jul 2026). An experimental estimate from the thermal band of Landsat (pixel 100 m, no atmospheric correction); the error can be 2 to 3 °C. This is the surface temperature, not the temperature at depth. Landsat 8/9, 18 Oct 2026 Mostly advantageous for fishing: fish are less shy and can still see the bait. Both natural and more vivid colors work well. Rich food for small fish, so cyprinids and the predators after them also stay near the surface. There may be less oxygen near the bottom. Aquatic plants cover about 87% of the area. Surface lures (rubber frog, popper) are ideal here, while classic rigs are hard to cast; look for clear openings, footbridges and banks without vegetation. The water has a smaller area than usual: fish retreat to deeper places, shallows and banks are exposed, and new obstacles may appear. Enter the water carefully. Fish activity rises with the temperature. Fish hold in deeper, slower places. The analysis is based on common angling rules and satellite data. It is an aid, not a bite forecast. The fishing regulations, the permit and the situation on site decide. Data have been stored since 11 Oct 2025 (55 periods of 5 days); the charts show how they develop. Download history (CSV) Estimates from satellite images with a resolution of 10 to 20 m, not a measurement in the water. They are affected by clouds, shadows, wind and banks; the shape of the water body is only approximate for this fishing district. Do not use them to decide about swimming or going onto the ice. Data: Contains modified Copernicus Sentinel data 2026, ESA, Copernicus Data Space Ecosystem. The procedure is described in the Methodology. The water quality index of fishing district VN Sigord is 75 out of 100. It is based on 4 groups of data from measurements and registers in the area. Good quality Five pillars from measurements and registers. A pillar without data is not counted in the index, so check the data reliability too. Oxygen has a weight of 30%, water pollution 25%, nutrients and bloom 20%, sources nearby 15%, acidity and hardness 10%. Detailed measurements are in the cards below. Summary: water and oxygen, pollution and life at the water, and how much they shift the conditions score We assessed 18 factors; 4 of them change the score. The adjustments range from −14 to +12 points so that they do not outweigh the weather and water temperature. They are counted in the score, in the ranking and in the filters. ≈ 7.7 °dH, ŠGÚDŠ atlas A harder, calcium-rich basin gives more productive water, in which trout and grayling grow better. Water with calcium and magnesium is more productive and buffers acidity swings better: trout production was higher in calcareous hard waters (Almodóvar et al. 2006), and an index based on dissolved solids and depth predicts fish yield from lakes (Ryder et al. 1974). In Irish streams, however, geology did not change trout density (Lehane et al. 2004), and Downing et al. (1990) showed that production is related rather to primary production. Hence only ±1 point. Hardness comes from the ŠGÚDŠ atlas, not from a measurement in the fishing district; it replaces the separately assessed bedrock of the basin. Sources: Almodóvar et al. 2006; Lehane et al. 2004; Ryder et al. 1974 metals and metalloids (above the standard at 1 of 2 stations), highest value 2.5 times the standard Metals, pesticides, PFAS and chlorinated solvents above the standard show the burden on the surroundings. The standards are set for drinking water and are stricter than the limits harmful to fish, so the reduction is small; metals can also come from rocks. PAHs are not counted in the score. Data reliability is 63% (2 stations within 10 km, the nearest 7.9 km, data from 2025); the adjustment was applied in full. Metals and metalloids, pesticides, PFAS and chlorinated solvents above the standard at stations within 10 km. The standards are drinking-water standards and stricter than the limits harmful to fish, so the reduction is small: one point for one or two groups of substances, two points for three groups or for a value at least five times above the standard. Metals are poisonous to fish, more so in soft water (Pagenkopf 1983), and PFAS accumulate in tissues (Giesy and Kannan 2001); metals can also come from rocks. PAHs are not counted. The adjustment is multiplied by the reliability of the data. Sources: SHMÚ, groundwater; Pagenkopf 1983; Giesy and Kannan 2001 Clays and loams, ŠGÚDŠ A fine-grained bottom is not typical of trout waters; the water clouds more easily. Trout production is higher in limestone hard waters (Almodóvar et al. 2006), but in Irish streams geology did not change trout density and the structure of the channel decided (Lehane et al. 2004). The evidence diverges; the weight is small. Sources: Almodóvar et al. 2006; Lehane et al. 2004 0.0× the average month, 0 of 16 observations in the year, iNaturalist Aquatic insects are scarce this month; food near the bottom matters more. Anglers fish "by the insects" (dry and wet fly). A measured relationship between catches and insect hatches is not documented in our sources. Data for these factors is missing or within the normal range: The rules are indicative and based on fishing practice and scientific studies; for each factor you can see how well it is supported. Weather, air pressure and water temperature affect the score more than this data does. pH and hardness, trace elements in water and sediment, landfills and contaminated sites, boreholes with analyzes (ŠGÚDŠ) pH 7.9modeled estimate water type Ca–Mg–HCO₃–SO₄ Mineralization 250 mg/l, soft water (7.7 °dH).

The chemistry of water and sediments is a model estimate from interpolated maps of the Geochemical Atlas of Slovakia, not current monitoring or a measurement in the stream. The proximity of a contaminated site or landfill does not mean that substances from it leak into the water. The locations of the objects are on the map in the Geology and geophysics section. Stations nearby and measured values Last exceeded in 2023: Exceeded in 2025: Groundwater reaches streams as base flow, so the connection to the stream at the fishing district is only indirect. Natural substances (iron, manganese, sulfates, conductivity) are not counted in the yearbook-based assessment. The data comes from the SHMÚ yearbooks (groundwater 2017 to 2025). A typical value from 2 groundwater stations within 10 km of the fishing district (nearest 7.9 km), measured in 2025. Closer stations carry more weight. This is groundwater near the fishing district, not a measurement in the watercourse itself. The standard is the limit that SHMÚ gives for the indicator (for drinking water); a value equal to the standard counts as an exceedance, as it does at SHMÚ. The label "somewhere above the standard" means that the typical value is below the standard but at least one station exceeds it; which one is shown on the tile. Fish are more sensitive to some substances than people are. < 0.01mg/l not detected Below the limit of quantification (0.01 mg/l), standard 0.5 mg/l. 2 stations. 0.03mg/l far below the standard Standard 0.5 mg/l.

Sources Fishing district VN Sigord has the number 4-3780-4-1. The reliability of data about the fishing district is 58 out of 100. Where the fishing district lies, what type of water it is, what its river basin is and what the organization writes about it Typical of gravel pits and reservoirs. In summer, fish often stay above the thermocline or at its level; below it there is little oxygen. Shallower sections with fewer shelters. In lowland streams they alternate with muddy ones; fish keep to banks, roots and obstacles. Even bank without coves. Fish concentrate at rare obstacles: logs, rocks, inflows. In summer the water warms up quickly and aquatic plants and algae thrive here. At midday fish move to deeper places. Grows by the water; the roots stabilize the bank and create shelters beneath the surface. The branches hang over the water and provide shade and insects. A typical tree of stream and river banks. A dense root system creates undercut banks and shelters, and the leaves decompose quickly. The explanation is general and based on the fishing district description in the data and on common fishing practice. Actual conditions on site may differ; check them before you fish. Changes in the surroundings and nature from 2019 to 2025: how the banks, vegetation and landscape around the water change. The images switch automatically; you can also browse them by hand.

Measurements and estimates What is measured right at the water for this fishing district, what is only partly supported, what is a model estimate and what is missing. The higher the number, the more you can rely on the indexes on this page. Rocks, faults, radon and geophysical measurements around fishing district VN Sigord. Bedrock, watercourse and springs on the map, values at the location of the water, geomagnetic activity and earthquakes. This is information about the environment; only small hypotheses marked with a confidence level (faults and rocks, geomagnetic storm) enter the score. The bedrock map needs JavaScript to be turned on. Geological map of Slovakia 1 : 50,000: rocks beneath the surface, from alluvial gravels and sands through clays to granites and limestones. Colors follow the ŠGÚDŠ legend; clicking the map shows a description of the rock at that spot. For anglers: Gravel bars and rocky riffles give a clean bottom and habitat for zander, perch and barbel. Clayey and muddy ground holds food for carp and bream. Limestone and dolomite give harder water that is richer in food than granite and quartzite. Radon risk of the bedrock (low, medium, high). It is based on the radioactivity of rocks and on fissures. The map shows the bedrock, not radon in water. For anglers: Radon is a natural tracer of groundwater. Bedrock with a higher radon risk (granite, gneiss, tectonic faults) tends to be where fissure water comes to the surface. Most of Slovakia is "medium", so mainly a high risk is of interest. Equivalent uranium in surface rocks from airborne gamma spectrometry (ppm). From 4 ppm the bedrock is usually classified as having an elevated radon risk. For anglers: A high uranium level is a sign of granite, gneiss and black shales, that is, rocks from which radon and dissolved substances get into the water. It has no direct meaning for bites, but it helps to read the geology of the area. Gamma radiation dose rate in air (nGy/h) from an airborne survey. It is the natural background of the bedrock, not pollution. For anglers: Higher values are found in rocks rich in uranium, thorium and potassium (granite, gneiss, flysch with shales). It complements the uranium map; for an angler it mainly shows where the bedrock changes. Anomalies of the Earth's magnetic field (ΔT, in nT) caused by rocks with magnetic minerals, such as volcanic rocks, basalts or amphibolites. For anglers: Fish (especially salmonids and eels) sense the magnetic field. Whether local anomalies affect their movement and bites has not been shown; it is treated as a hypothesis. Click or tap the map to find the value at that location. low Bedrock with a low radon share. 2.6ppm common Typical background of the rocks. 7.7ppm below the crustal average Natural background of the rocks. 1.28% below the crustal average Natural background of the rocks. 51nGy/h around the world average Natural background of the bedrock. -81nT below the average of the surroundings Deviation of the magnetic field from the average of the surroundings. The values apply to a single spot (marked with a dot on the map), not as an average of the whole watercourse or river basin. Radon is a natural tracer in groundwater; the map does not include radon in water, only the bedrock risk. Mark on the dial: the average of the upper continental crust (uranium 2.7 ppm, thorium 10.5 ppm, potassium 2.3%; Rudnick and Gao 2003) and the world average of the natural outdoor dose 59 nGy/h (UNSCEAR 2000). The needle does not swing towards “good” or “bad”; it only shows where the value lies. Elevated uranium or radon is only information about the rock. It has no proven significance for bites; it helps to read what bedrock the water comes from. up to 250 m fault nearby Tectonic fault on the geological map. 0 none marked None within 1 km. observed at the surface covered by younger sediments inferred Fissure groundwater flows out of the bedrock along faults and at springs. It tends to be cooler in summer and warmer in winter than the water in the stream, so according to anglers' experience fish stay near such places in extreme weather (summer and winter islands of a more suitable temperature). However, fresh fissure water can have little oxygen. This is anglers' experience, not a phenomenon measured at this fishing district. Faults are from the geological map at 1 : 50,000. Springs come from a hydrogeological map that covers only some regions, so zero does not mean there are no springs there. 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.

Detailed geology and geochemistry of the whole stream: rock under the water, water composition, elements in sediments, radiation, geothermal potential, metals, gold in sediment, mine workings, boreholes with analyzes. Highest forecast Kp in the next 24 hours: 1.7 (quiet field). Kp (0 to 9) measures the fluctuation of the Earth's magnetic field caused by the solar wind. From 5 it counts as a geomagnetic storm. Fish, especially salmonids and eels, sense the magnetic field. That their bites depend on Kp has not been shown, though: these are anglers' observations and hypotheses. The value is the same for the whole of Slovakia. It enters the activity score only during a strong geomagnetic storm (a hypothesis, −1 to −2 points). According to angling lore, fish (especially catfish and eels) react restlessly to tremors beforehand or stop biting. This is not reliably proven, and with weak tremors it is coincidence. People mostly do not notice deeper tremors from the Carpathians (for example near Komárno and Dobrá Voda) at all. The GEOFON catalog is global; weak tremors near Slovakia may not all be in it. It is not counted in the activity score. Data: © ŠGÚDŠ (geological, geophysical and hydrogeological maps), NOAA SWPC (Kp index), GFZ GEOFON (earthquakes). A link between the geomagnetic field, tremors or radon and fish bites has not been reliably proven, so they are not counted in the activity score. The method is described in Methodology. Wildlife, birds and plants observed around fishing district VN Sigord. Species that have been observed or recorded around the water. Wildlife, plants and hazards do not enter the fishing conditions score and are for information only. The name of a species leads to its page. The most common duck; it nests by almost every water with bankside vegetation. It stands in the shallows and lies in wait for small fish. It is easy to see along the banks of ponds and slow streams. A large white heron that hunts fish and frogs in the shallows. In Slovakia its numbers are rising, and in winter it can also be seen by watercourses. A fish-eating bird. It nests at large reservoirs and in winter also stays on streams with open water. A large white waterbird that nests by slow waters, reservoirs and ponds with vegetation. A diving waterbird with a crest on its head. Hunts small fish and insects, nests on a floating nest in the reeds. Predatory insect. The larvae live underwater for several months to years; adult dragonflies hunt in the air above the water. An insect with aquatic larvae. Adults live only briefly and hatch all at once in swarms. Black with yellow spots. Lives in deciduous forests by clean mountain streams; the larvae develop in the stream. The largest native toad. In spring it migrates to water, where it breeds. A herbivore that changes the stream and its banks with dams and burrows. It is protected. It creates shallows and pools where fish and insects thrive. A harmless snake with two yellow spots on the nape. It swims well and hunts frogs, fish and newts. A riparian tree whose roots reach below the water surface. Tall grass that forms extensive reed beds around ponds and on banks. A wetland plant with a brown cylindrical fruiting spike. A tall wetland plant with yellow flowers that grows on damp banks. An invasive herb from East Asia that forms dense stands up to three meters tall. A tiny floating plant that can cover the whole surface of standing water. Lives in the mountain forests of northern and central Slovakia. Near water it hunts fish and drinks. How to protect yourself: In mountain fishing districts move noisily, do not leave fish, entrails or bait leftovers near your tent, and store food away from where you sleep. If you see a bear, do not run, talk calmly and back away slowly. Never approach the cubs. Transmits tick-borne encephalitis and Lyme disease. It waits in tall grass and in the vegetation along banks. How to protect yourself: From spring to autumn check yourself after fishing, use repellent and tuck long trousers into your socks. Remove a tick as soon as possible with tweezers. A vaccination against encephalitis exists. They breed in standing water, so they are worst around reservoirs, oxbow lakes and floodplain forests, especially at sunset. How to protect yourself: When fishing in the evening and at night wear long sleeves, repellent and a net. Warmth and humidity after rain speed up mosquito development. A venomous snake that basks on rocky slopes, in wetlands and at forest edges near water. How to protect yourself: It is shy and bites only when threatened. On rocky banks do not reach with your hand between the stones, and wear sturdy footwear. After a bite stay calm, do not move the affected limb and call 112. Large biting flies. They are most active on hot, windless days near water and on meadows. How to protect yourself: They sting painfully, especially in summer around midday. Light-colored clothing with long sleeves and repellent help. An invasive plant that grows along stream banks and on wet meadows. In sunlight its sap causes skin burns. How to protect yourself: Do not touch it and do not walk through the vegetation. If the sap gets on your skin, wash it off with water and soap and protect the area from the sun. See a doctor for larger burns. It comes to the water to wallow and drink, mainly at dusk and at night. How to protect yourself: A wild boar sow with piglets can be aggressive. Keep your distance, do not spend the night on a game trail and do not leave food scraps near the water. Wildlife, plants and hazards: records come from observations and also reflect where observers move around; they are not density measurements or a guarantee of an encounter. They apply to the surroundings of about 35 × 55 km. Nearest fishing districts around VN Sigord: 6. Nearest fishing districts in the same river basin
