Yanco Creek and Tributaries Advisory Council - YACTAC's footprint is in the Riverina, between Narrandera and Moulamein, including the towns of Morundah, Jerilderie, Conargo and Wanganella. Urana is located in the unregulated section of the Billabong Creek.

The Yanco Creek and Tributaries Advisory Council Inc (YACTAC) footprint is located between Narrandera and Moulamein, with over 800kms of creek frontage covering a distance of 250km from east to west. The Yanco, Billabong, Colombo and Forest Creek, (known as YCS), network is an anabranch complex that broadly connects the Murrumbidgee River with the Edward River. Water is diverted from the Murrumbidgee River into the Yanco Creek at the Yanco Weir. Unregulated flows from the Billabong Creek enter the regulated system east of Jerilderie, in addition to regulated inlets via Coleambally Irrigation Co Ltd and Murray Irrigation Ltd drainage systems.

There are nine volunteer representatives on the management team of YACTAC. Over 150 landholders voluntarily contribute to the Yanco Creek System Natural Resource Management Plan (YCS levy) which is charged through WaterNSW and administered by YACTAC. The levy commenced in 2006 and is used to maintain and improve the health of the creek system.

The YCS supports the economy of the region by providing town water, irrigation and stock/domestic water. The towns of Jerilderie, Conargo, Urana, Morundah and Wanganella rely upon the water in the system. The indigenous cultural groups are Wiradjuri, Yorta Yorta, Barapa Barapa and Wamba Wamba. For the indigenous custodians of the region, the natural landscape feature highly productive watercourses, numerous wetlands and floodplains.

The YCS is recognised for its environmental values, particularly as it supports one of only two known self-sustaining populations of the nationally endangered Trout Cod. The creek provides habitat conditions that were once widespread in the lowland Murray-Darling Basin but are now extremely rare: perennially fast flowing water, good water quality, good riparian vegetation, low macrophyte density and dense in-channel snag habitat. The series of wetlands along the system provide habitat for international migratory bird species, native fish and other aquatic species. It provides a largely undisturbed riparian corridor between the Murray and Murrumbidgee.
