es of the Murray including the Edward River and the Wakool River are also managed to provide irrigation water to irrigators along those waterways. Managed flow along those waterways bears little correlation to natural flow regimes, with peak flows occurring during peak irrigation demand (summer) rather than during peak runoff (early spring). Irrigated agriculture is the main industry of the towns within the area which include Finley, Deniliquin and Jerilderie. The irrigation area has become increasingly controversial in the early 21st century, after consecutive years of drought and a growing Australian population have led to demands for greater levels of water conservation.
