There are four dam lakes in the central part of the Sakala Upland, in Viljandi county, Viljandi municipality, in the village of Viiratsi.
The lakes are successively swollen into a ditch flowing through the village. A Viiratsi singing stage has been built by the highest lake.
The Commander-in-chief of the Estonian Army Johan Laidoner (1884–1953) was born in Raja farmstead near Viiratsi, site now located in nearby Vardja village. The coordinates are taken from the Maa-amet website
