The Murray River National Park consists of Katarapko Creek, Lyrup Flats, Bulyong
Island and Eckert Creek. The floodplain is considered important for the preservation
of red gum and black box woodland habitat.
Katarapko Creek, a minor branch of the River Murray is across the river from
Loxton. Here, in quiet backwaters and several horseshoe lagoons are numerous
waterbirds. Many protected species nest and live on the island, including
peaceful doves, sulphur-crested cockatoos, sacred kingfishers striped honey-eaters,
regent parrots, crimson rosellas, blue-faced honeyeaters, pied butcher-birds,
pelicans, ibis and darters. The waters around Katarapko Island are excellent
for canoeing and fishing.
