Water Quality and Night Sky Brightness Measurements for Selected Lakes in Kraków

This dataset presents a comprehensive set of water quality measurements collected from six lakes in Kraków, Poland: Staw Płaszowski, Zalew Nowohucki, two ponds in Park Lotników, Staw Dąbski, and Bagry. It includes key environmental parameters such as pH, temperature, dissolved oxygen concentration, conductivity, chlorophyll-a levels, cyanobacteria abundance, and turbidity. Additionally, the dataset incorporates measurements of night sky brightness (SQM), recorded concurrently with the water sampling.
