	Summary:
	This paper represents the steps necessary for the proper establishment of the parameters representative when computing the CCME Water Quality Index, demonstrated on the example of Lake Ludas. In order to avoid misleading representation of the surface water’s quality, it is desirable to process the available water quality data and then chose only the parameters that influence the changes in water quality of the considered site. This is usually conducted by computing the Pearson’s correlation coefficient for all of the available parameters. The results of this analysis is the ability to better asses which of the accessible data should be included in the computation of the CCME WQI. The method is presented on the water quality data for Lake Ludas for the year 2012.
