Prague – The quality of water in natural swimming pools in the Czech Republic remains good even in mid-July. Hygienists have not announced a bathing ban anywhere yet. In several places, the water is not suitable for swimming, such as in Radava near the Orlické reservoir or the New Pond in Příbram. Swimming in the Hracholusky dam in Butov cannot be recommended to people either. After heavy rains, the transparency of the water decreased in some ponds. In some swimming pools, on the other hand, the water quality has improved since last week, for example at the Podolsko na Orlík camp.

In the Central Bohemian Region, the water in the Orlická dam deteriorated. It is rated three on a five-point scale and has a higher cyanobacterial content. For several weeks now, Luboš Mandík, the head of the general and communal hygiene department for the Příbram district, has told ČTK the same level of hygiene for several weeks now. According to him, the water on Orlík is significantly worse than two weeks ago. “However, there is no danger of bathing,” he added. Water unsuitable for swimming has been in the New Pond in Příbram for a long time, and several swimmers had an itchy rash, which indicated the occurrence of cercariae. Hygienists did not forbid swimming in the New Pond, but the fourth degree should remain there. The water in the pond is fine in terms of other indicators and does not contain cyanobacteria. However, people can bathe only at their own risk.

Most swimming pools in the Pilsen region still have water suitable for swimming, the Košutecké lake in Pilsen has been deteriorating for several weeks this year. According to the latest available measurements of hygienists, the water is also worse at the swimming pool in Annín in the Klatovy region. After the rains, the transparency of the water decreased in some ponds. The largest body of water in the region, the Hracholusky dam, has water suitable for swimming, especially at the dam; at the opposite end in Butov, swimming is no longer recommended due to the cyanobacterial bloom, hydrobiologist Jindřich Duras told ČTK. Bolevecký pond suffers from a lack of water, it lacks more than a meter. But the conditions for swimming are very good.

In the South Bohemian Region, the quality of bathing water near the Podolsko na Orlíku camp has improved compared to last week, and it has only slightly worsened properties. There is also better water in the Hejtman pond in the Jindřichův Hradec region. The water in Radava near the Orlické reservoir is still unsuitable for swimming. On Monday, July 19, hygienists will take samples at three places on Lake Lipno. At the last inspection there were relatively favorable values.

Natural swimming pools in the Vysočina region usually have safe and suitable water for swimming, yet in some places the water quality has deteriorated since the beginning of July. Due to the turbidity caused by rain, this is especially true for water areas in the Havlíčkův Brod region. Cyanobacteria and higher amounts of chlorophyll remain in the Sedlice dam in the Pelhřimov region. After swimming in this dam, people should take a shower.

In the Hradec Králové Region, bathing water is suitable, with the exception of the Silver Pond in Hradec Králové and the Oborský Pond in Jinolice in the Jičín Region. After swimming in the Silver Pond, people should take a shower with clean water. In the Oborský pond, swimmers have to reckon with poorer water transparency. In the Pardubice Region, hygienists found slight pollution only in the Rosnička pond in the Svitavy region and the Dlouhý pond in the Orlickoústecko region. However, they do not pose a risk to bathers, it is advisable to take a shower after bathing. After the floods, the Tyrš swimming pool in Vysoké Mýto is out of operation.

In most natural swimming pools in the Ústí nad Labem region, the water quality is still good. Hygienists recorded an increased occurrence of cyanobacteria and algae in Lake Chmelař in the Litoměřice region, in the flooded quarries Varvažov and Chlumec in the Ústí nad Labem region. At the swimming pool in Chabařovice near Ústí nad Labem, the transparency of the water is reduced.

In the Zlín Region, the water quality deteriorated in Pahrbka, a blind arm of the Morava River near Napajedla in the Zlín Region. When bathing, this slightly increases the probability of health problems, especially in more susceptible individuals, Eva Javoříková from the regional hygiene station told ČTK. In other monitored natural swimming pools in the region, the water is fine, but problems with its quality persist in the habitat in Prostřední Bečva in the Vsetín region. In the South Moravian Region, the Výrovice reservoir in the Znojmo region has muddy water, but the water is suitable for swimming. Other swimming pools in the region have good water.

In the Olomouc Region, the water quality in the Plumlovská Dam remains at the same level as in the last abstractions two weeks ago, and hygienists rate it as grade two on a five-point scale. According to hygienists, the water is safe, but it would be appropriate to take a shower after bathing. On the other hand, on the gravel-sand lakes of Poděbrady, which are the second monitored locality for hygienists, people can swim without any worries.

The water quality in natural swimming pools in the Frýdek-Místek and Novojičín regions, where hygienists took inspections this week, is good. The only exception is the Brušperk reservoir in the Frýdek-Místek region. The reason is the risk of infection with cercariaus dermatitis, which is caused by larvae of moths and manifests itself with an itchy rash, but also cough and abdominal pain.
