Received: April 25, 2023
Accepted: July 19, 2023		 During the summer months from 2014 to 2016, water was sampled at two lakes in Zagreb, Jarun and Bundek, with the aim of determining the number of colonies of microbiological indicators of Escherichiae coli and intestinal enterococci. We have investigated the dependence of microbiological water quality indicators on sampling points. Also, we were interested in determining the influence of the season of the year. This research identified that regular monitoring of microbiological indicators is necessary, especially at locations used by people for recreation or other purposes, in order to prevent possible infections.
