Pusta reka je pritoka Vlasine. Izvor Puste reke se nalazi ispod vrha Preslap u podnožju Suve planine u ataru sela Donji Prisjan . Reka protiče jednim delok kroz Zaplanje a drugim delom Leskovačkom kotlinom odnosno kroz opštine Gadžin Han i Vlasotince. Dužina Puste reke je 20 km, a sve njene pritoke imaju dužinu od 135 km.
Reka nastaje u ataru sela Donji Prisjan spajanjem rečica Ropot, Dubravske reke i Komaričke reke. Rečica Ropot izvire podno Suve Planine između Štrbovca i Velikog Krčimira.
Na relativno kratkom rastojanju se ulivaju i rečice Crvila i Rakovac.
