The Belyando-Suttor sub-catchment comprises the southern half of the Burdekin surface water catchment. It consists of a series of remnant sedimentary basins that form extensive plains and lowlands, with a braided stream network. The Belyando River and Suttor Rivers drain mountain ranges and high plateaux on the margins of the sub-catchment. Cracking clays predominate through much of the sub-catchment. Large ares in the eastern plains and adjacent slopes have dispersive properties due to past salinisation and leaching. Although rainfall is lower and degree of leaching limited relative to the degree of leaching limited relative to the Upper Burdekin and coastal areas, soil organic matter and nitrogen fertility are low.
Beef cattle production and dryland cropping are the main agricultural land uses, with cattle production mostly on rangelands (Roth et al.). Several conservation reserves are located with the sub-catchment.
