Some 300 m below Korkuli hoemstead river disappears underground through several sinkholes. Here forms some 0,5 km long underground river. The outlet of this river is especially impressive during the high water in spring time. Near Korkuli River there is vertical pit made by geologists in order to investigate the underground karst cave found during the geological investigations around Aizkraukle dam (for hydropower plant).
