After an underground flow of about one kilometer, the stream resurfaces in the neighborhood of Medaković II, but one kilometer later, in the neighborhood of Marinkova Bara, it goes underground again. Formerly, it used to flow through the neighborhoods of Dušanovac, Autokomanda and Jatagan Mala. The area in the lower valley of the now underground stream was used for digging earth and gravel which were used to cover and drain the swamps on the Sava's right bank, so that neighborhoods of Savamala and Bara Venecija could be constructed, and for the building of Belgrade's central railway station. After the works were completed, the area around Mokroluški potok was left as a steep, elongated cut in the ground and so was given its present name (Prokop).
