Dunavski park lake in Novi Sad drained for cleaning, fish did not survive
N1 relays 021's report: Gradsko zelenilo drained the Dunavski park lake for regular cleaning and handed the turtles to the Institute for Nature Conservation. Fish that, according to the company, ended up there because residents brought them into the lake themselves were not saved during the works and died. N1 also repeats that the cleaning is carried out every three years using JKP Vodovod i kanalizacija equipment to remove mud.

Workers are removing mud, waste, stones, and dry branches; water is planned to return in a few days.
