Polskie Rzeki is a free Android app developed by Maksym Krawczyk Studio that provides real-time water level information for rivers and lakes in Poland. The app allows you to easily and clearly observe the current water levels, view flow charts for each measuring station, check the temperature, and verify ice phenomena and the degree of vegetation overgrowth in the reservoir.

You can locate the measuring stations on the map, which can be customized to suit your needs. The app also includes filtering and saving favorite stations, adding your own points, and events. With Polskie Rzeki, you can stay informed about the water levels in your area and plan your activities accordingly.
