It is surrounded by mild slopes of Cincar, Vitorog, Plazenica and Raduša mountains. Relief of Kupreško polje is a typical karst relied with hydrographic structures of the underground rivers and dolinas. Kupreško polje’s flood area is around 36,22 km2 and hydrographically it is a part of Cetina and Pliva river basins. There are a several streams that flow through the polje and sink underground at its end. Three permanent lakes are Kukavičko, Turjača and Rastičevsko lakes.
