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.
Elevation profile of the watercourse
How the watercourse falls downstream: fall, gradient and water speed.
Fast watercoursePodhorský potok: fast water, stony bottom, riffles and the pools below them. Typical trout waters.
Elevation profile of the watercourse: from 550 to 142 m a.s.l. over 25.3 km.Fishing districts in order from the highest (left) to the lowest. There may be a section without a fishing district between districts; it is not displayed.
Highest point
550 m a.s.l.
Lowest point
138 m a.s.l.
Fall of the fishing districtsFallThe difference in altitude between the upper and lower end of the fishing district in metres. The greater the fall over a shorter length, the faster the water.
411 m
Average gradientWatercourse gradientFall per kilometre in per mille (‰, metres per kilometre). Up to 2 ‰ is a slow lowland river, 5 to 10 ‰ a foothill river (grayling, trout), above 10 ‰ a fast stream.
16 ‰
SinuositySinuosityThe length of the watercourse divided by the straight-line distance between its ends. 1.0 is a straight watercourse; above 1.3 it meanders strongly. Meanders create pools under the banks and shallows in the reaches between.

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.
