Cadiangullong Creek is a mostly-perennial river flowing through New South Wales, Australia. It forms part of the Lachlan sub-catchment within the larger Murrumbidgee and Murray–Darling basin system. The waterway is associated with Cadiangullong Dam, which creates a significant impoundment along its course. The surrounding area features a network of trails, including a moderately challenging 3.6-mile loop trail near Springside that follows sections of the creek and a fire trail, offering anglers opportunities for both bank and wade fishing access along portions of the stream.
