Keeping the waters in good condition is a mandatory state task, but the condition of the waters changes very quickly and continuously due to intensive use and loads. There are also signs of change that can be seen on the water with the naked eye, such as e.g. algae growth or the disappearance of typical species. The appearance of new species, or the excessive reproduction of certain species, can also be a consequence of this. In order to get an accurate picture of the state of the waters and to assess the extent to which undesirable organisms have multiplied in them, or where and when really large algae blooms occur, we also ask for your help! If you're fishing or just hanging out at the water's edge, please share what you see with us.
