Ecohydrology planning and infrastructure design in the Nimmie-Caira

The Nimmie-Caira forms part of the lower Murrumbidgee River system located northwest of Balranald in southern NSW. The Nimmie-Caira comprises the southern floodplain for the Murrumbidgee River near the confluence with the Lachlan River. The floodplain area is dominated by lignum shrubland that supports significant colonial nesting bird rookeries.

In 2012, the NSW and Commonwealth Governments entered into an agreement to purchase the land and water associated with the Nimmie-Caira irrigation area, returning the water to the system for ecological outcomes, and the land for both productive use and ecological outcomes. This venture involved the purchase of 84,417 ha and 173GL of supplementary water (Lowbidgee) entitlement. Alluvium was engaged by the NSW Government across a number of projects to re-configure the Nimmie-Caira water delivery system and landscape to service the ecological requirements of the area.
