The score, the best window of the day and what pushes it up or down Loading data… Water level, temperature, modelled flow and gradient Kežmarok – Poprad · level stable, gauge 21 km away The level is measured at an SHMÚ gauge; it is not the depth of the water in the fishing district. Loading data… Gentle gradient The current is noticeable, with shallows and slacks alternating. A transition between a lowland and a foothill watercourse. The district is short, so the slope is only indicative (the relief model has a resolution of tens of meters). 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 26 min. Full moon around 24 Nov, new moon around 9 Nov. 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. Course of the water, spots along the water, character and basic data The line shows the course of the fishing district according to the "Rybárske revíry" data 2026. Verify access points and exact boundaries on site. It warms up and cools down quickly. Fish are shy; a quiet approach and a delicate rig help. Well-oxygenated water and plentiful food (aquatic insect larvae). Typical of the grayling and barbel zones; gravel bars also serve many fish as spawning grounds. Typical of fast mountain and foothill streams. There are shelters for trout and other fish among the stones, but your rig often gets snagged. Gentle bends: on one section you will find both deeper scours and shallower bars. A balanced stretch: there is a source of insects and also enough light for aquatic plants. 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. Weirs, drop structures or barrages: a barrier to fish migration; a plunge pool usually forms below the structure. Check the fishing bans near structures. 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. Spots within 3 km of the watercourse are shown. Closed season, fishing hours, minimum sizes and daily limit. For guidance only: check them in the fishing regulations of the fishing district 1 Jan – 31 May 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). June, July, August4.00 – 22.00 h September, October5.00 – 21.00 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 district or the fishing guard. This is a summary. For baits, hooks and groundbait also read the fishing regulations of the 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 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 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 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). On the same stream and nearest in the basin Loading the 3D terrain model… Water quality, river basin, bottom, fish, aquatic insects, wildlife and hazards from open databases. Except for wildlife and hazards, they are also included in the activity score. The water is in the top 7% of 41 grayling fishing districts with data. Reliability medium: we used 5 water data points; the rest are missing and are not part of the assessment. gradient 3.1 ‰, 519 m a.s.l. → grayling zone Based on gradient and elevation, the stream lies in an area that corresponds to the grayling zone. This is a natural zone for grayling. European streams are divided from source to mouth into zones with typical fish: trout, grayling, barbel and lowland; they are determined mainly by gradient and stream size (Huet 1959), and the zones can also be used to assess the condition of streams (Aarts and Nienhuis 2003). We estimate the zone from the gradient of the fishing district's line and its elevation; it is a simplification without stream width. A match between the zone and the fishing district type adds +1 to quality, a clear mismatch −1. Sources: Huet 1959; Aarts and Nienhuis 2003 ≈ 11.3 °dH (2.0 mmol/l of calcium and magnesium), ŠGÚDŠ atlas Harder water with enough calcium and magnesium is more productive, has a larger food supply and buffers acidity swings 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 pH 8.2, 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, aluminium 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 ≈ 351 mg/l, ŠGÚDŠ atlas Medium mineralisation corresponds to productive streams and reservoirs. Dissolved solids (mineralisation) 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 0 elements among the highest 10 % in Slovakia (ŠGÚDŠ atlas 1999) None of the toxic elements in river sediment is among the highest values. 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 grayling 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 mineralisation 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). We assessed 18 factors; 5 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. ≈ 11.3 °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 site Údol, bridge to Plavnica on Poprad, 3.8 km from the fishing district, standard not met in 1 of 4 years (2022 to 2025); in 2023: BOD₅ (biochemical oxygen demand), COD (chemical oxygen demand), total organic carbon, nitrites, benzo(a)pyrene The nearest SHMÚ monitoring site on this watercourse does not meet water quality standards. Lack of oxygen and organic pollution weaken fish directly, ammonium ions and nitrites are toxic to them, and further nutrients promote algae. All four years are counted, and newer ones carry more weight. The location of the site is only approximate (by water body), so it is counted with less weight. An unmet standard does not mean the fish do not bite; the reduction is at most 5 points. The nearest SHMÚ monitoring site on the same watercourse: unmet water quality standards for the years 2022 to 2025 (newer years carry more weight). Lack of oxygen and organic pollution directly weaken fish (Davis 1975), ammonium and nitrites are toxic, and nutrients feed algae. The exact amount by which an unmet standard lowers the bite is not verified, so this is angling practice and caution. The deterioration is at most 5 points and only lowers: what SHMÚ does not report is not proof of cleanliness. Benzo(a)pyrene and other PAHs are not counted in the score because most watercourses exceed their extremely low standard. Sources: SHMÚ, surface waters; Government Regulation of the SR no. 269/2010; Davis 1975 nitrates typically 4.1 mg/l (standard 50), ammonium above the standard at 1 of 3 stations Groundwater reaches streams as base flow and carries nitrogen from fields and waste. Nitrates feed algae and contribute to nighttime oxygen crashes; nitrites are toxic to fish. Nitrites and ammonium can also be natural in deep groundwater, so at most one point is deducted for them. The data reliability is 100% (3 stations within 10 km, nearest 1.6 km, data from 2025), and the adjustment was applied in full. Groundwater reaches streams as base flow. The typical nitrate value from stations within 10 km (moderate from 25 mg/l, significant from 50 mg/l, which is the drinking-water standard) indicates how much nitrogen the water brings: it feeds algae and contributes to night-time oxygen crashes (Camargo et al. 2005). Nitrites and ammonium above the standard at any station add one point, because nitrites are poisonous to fish (Lewis and Morris 1986); in deep groundwater they can also be natural, so only one point. The adjustment is multiplied by the reliability of the data. Sources: SHMÚ, groundwater; Camargo et al. 2005; Lewis and Morris 1986 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 23 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. Polycyclic aromatic hydrocarbons. The standard for benzo(a)pyrene is extremely low (0.17 ng/l), so most streams exceed it; the main sources are combustion and atmospheric deposition. The location of the site is only approximate (based on the water body), so the actual sampling point may be elsewhere on the watercourse. The data comes from the SHMÚ yearbooks (surface waters 2022 to 2025). The yearbook lists the sites that failed the standard; a site missing from the yearbook is not considered clean. We determine the distance and the match of the watercourse name ourselves, so the assignment is indicative. Exceeded in 2025: Exceeded in 2025: Last exceeded in 2018: 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). Treatment plants within 2 km of the fishing district. The treatment plant need not lie upstream of the fishing district; we do not assess the watercourse at the plant. Load is the ratio of the pollution produced to the capacity of the treatment plant (PE = population equivalent). Watercourse from the HydroRIVERS database matched with the fishing district, line deviation about 114 m The data come from a global database with a coarser resolution (tens of metres), so they are only approximate for small waters. Depth and volume are model averages. After rain the water quickly turns turbid and fish hunt more by smell. Springs and groundwater outflows bring cooler water into the watercourse in summer and warmer in winter; fish stay near them in extreme weather. 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: gravel, bedrock, stony; the geological map shows something different, and the 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. Few insects November: 0.0× the average month 0.0× the average month, 0 of 23 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. A typical value from 3 groundwater stations within 10 km of the fishing district (nearest 1.6 km), measured in 2025. Closer stations carry more weight. This is groundwater near the 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. 0.25mg/l close to the standard Standard 0.5 mg/l. Range 0.005 to 0.61 mg/l, 3 stations.

Sources 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 small bird that dives and runs along the bed of rapids after insect larvae. Nests by clean mountain streams. Black with yellow spots. Lives in deciduous forests by clean mountain streams; the larvae develop in the stream. An insect with aquatic larvae. Adults live only briefly and hatch all at once in swarms. A small bird that dives for little fish. It nests in steep banks of clean streams. Predatory insect. The larvae live underwater for several months to years; adult dragonflies hunt in the air above the water. 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. The largest native toad. In spring it migrates to water, where it breeds. A harmless snake with two yellow spots on the nape. It swims well and hunts frogs, fish and newts. It hunts fish, crayfish and frogs. It is strictly protected, and its presence is considered a sign of fairly clean water with plenty of fish. A non-native turtle from America that got into the wild from home pet keeping. It is invasive in Europe. An invasive herb from East Asia that forms dense stands up to three metres tall. A riparian tree whose roots reach below the water surface. An invasive plant from the Himalayas, up to two metres tall, with pink flowers. It overgrows the banks of watercourses. Tall grass that forms extensive reed beds around ponds and on banks. A wetland plant with a brown cylindrical fruiting spike. 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 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. 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. 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. 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. A shy predator of the forests. It comes to the water at night and at dusk. How to protect yourself: Attacks on people are very rare. Keep your camp tidy, do not feed wildlife and keep your dog on a leash. 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. 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. 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. 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. medium Common for most of Slovakia. 2.0ppm low Low background of the rocks. 5.9ppm below the crustal average Natural background of the rocks. 1.15% below the crustal average Natural background of the rocks. 41nGy/h below the world average Natural background of the bedrock. -16nT 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. 1 groundwater by the watercourse Within 1 km. covered by younger sediments 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 centre.

Proximity of a mine working or burden does not mean the water is polluted. The chemistry of water and sediments is a modelled estimate from interpolated maps of the Geochemical Atlas of Slovakia, not current monitoring or a measurement in the stream.

Highest forecast Kp in the next 24 hours: 4.7 (unsettled 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). All these tremors are very shallow; they are probably mining tremors (for example in Polish and Czech districts), not tectonic activity. 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.

Fish activity indexOur calculation (0–100): the base is set by water temperature, adjusted by light, turbidity, oxygen, weather and other factors according to how well they are supported by studies. For each factor you can see the confidence and the source. A planning aid, not a bite forecast.Water
Water level
Water levelThe water level at the nearest SHMÚ gauge in centimetres above the gauge zero. It is the water level at the station, not the depth of the water at the fishing district.Modelled flow
Modeled flowAn estimate of the amount of water in the river (m³/s) from the GloFAS model, not a measurement. The resolution is about 5 km, so on small streams it may show a larger river nearby.Elevation profile of the watercourse
Elevation profileHow the altitude of the watercourse changes downstream. It is calculated from a digital relief model (tens of metres), not from a water-level measurement, so it is approximate, especially for narrow streams.Weather and forecast
Weather and forecast
Sky: sun, moon and solunar windowsSolunar periodsCalculated from the position of the Moon: major periods (about 2 h) around the Moon's passage above and below the horizon, minor periods (about 1 h) around moonrise and moonset. A scientifically unconfirmed theory: in a study of 361 fishing trips (Quigley et al. 2023) it did not predict bites. We treat it as a hypothesis with a weight of at most ±2 points.

Reservoir depth (HydroLAKES)Average depth, volume and water retention time in the reservoir from the HydroLAKES database (WWF). The depth is estimated by a model from the surrounding terrain, so it is approximate.Bottom and bedrock
Bottom and bedrock (ŠGÚDŠ)The bedrock under the water according to the hydrogeological map of Slovakia at 1 : 50,000 (ŠGÚDŠ). It tells whether the surroundings are gravelly, sandy, clayey, muddy or rocky.Aquatic insects
Aquatic insect swarming (iNaturalist)How many observations of mayflies, caddisflies and stoneflies people nearby recorded this month compared with the annual average. For fly anglers it hints at insect hatches.
Mayflies0Mayflies: dry fly on the surface, especially at dusk.
Caddisflies0Caddisflies: in the evening and at night by the bank; a nymph and a wet fly also work.
Stoneflies0Stoneflies: clean, cold streams, often already at the end of winter and in early spring.Photo credits
