Lake Vrutci ({{langx|sr|Језеро Врутци|Jezero Vrutci}}) is an artificial lake in western Serbia, in the municipality of Užice. The lake was created in 1983{{cite web|url=http://www.bastabalkana.com/2009/07/jezero-vrutci-stvarno-mesto-gde-sveti-georgije-ubiva-azdahu/ |title=Zmajevo jezero Vrutci na Zlatiboru| date=31 July 2009}} by damming the Đetinja River, near the village of Vrutci. It was created with the purpose of supplying water to the city of Užice. It is narrow, around 7 km long, and lies at an altitude of about 700 m.{{cite web|url=http://jezerovrutci.com/ |title=Jezero Vrutci}}

In December 2013, a toxic cyanobacterial bloom caused by Planktothrix rubescens was observed in the lake, whose water was immediately banned for human consumption, and soon after for bathing and fishing. The city was left without water supplies for several days, when an emergency link was built to an alternative source, Sušičko vrelo reservoir.{{cite web|url=http://www.zdravlje.gov.rs/showelement.php?id=7124 |title=Water from Užice water supply is safe for drinking and for food preparation |publisher=Serbian Ministry of Health |date=7 February 2014}} A long-term treatment for revival of the lake started, but {{as of|May 2015}} the toxic algae were still present in the water.{{cite news|title=U jezeru Vrutci i dalje plivaju alge |url=http://www.blic.rs/Vesti/Srbija/555796/U-jezeru-Vrutci-i-dalje-plivaju-alge |date=4 February 2015 |publisher=Blic}} Only in February 2019, after the modernization of the water plant was finished, the water from Vrutci became appropriate for public usage.{{cite news | author = Branko Pejović | title = Вода из ужичког водовода од јуче може да се пије | trans-title = Water from the Užice waterworks can be used from drinking since yesterday | newspaper = Politika | page = 15 | language = Serbian | date = 19 February 2019}}
