The Berthong Creek, a mostly–perennial river^[3] that is part of the Lachlan sub-catchment of the Murrumbidgee catchment within the Murray–Darling basin, is located in the South West Slopes, and Riverina regions of New South Wales, Australia. The Berthong Creek is only connected to the Murray Darling basin when the Bland Creek, the Lachlan and Murrumbidgee Rivers are in flood.

Course and features

The Berthong Creek (technically a river^[3]) rises west of Wombat, between the towns of Stockinbingal and Young, and flows generally north by west, joined by one minor tributary, before reaching its confluence with the Bland Creek. The creek descends 182 metres (597 ft) over its 40-kilometre (25 mi) course.^[1] The creek is impounded by the Berthong Dam south of Yannawah.
