The pond is an oxbow lake, a remnant of the meanders of the old Sava River, whose main stream presently flows more southward.
Due to its shape the swampy bed of the pond, situated between the villages of Obrež and Kupinovo, is called “The Horse-shoe” (potkovica).
Higher grounds with cut-in depressions and old oak forests are called “The Hoof” (kopito).
Obedska pond is one of the world's oldest nature areas, first administrative protective measures having been introduced in 1874, when the Habsburg Empire protected it as hunting ground of the royal family.
Presently, it has first-category legal protection status, denoting a natural asset of exceptional value.
