Whining river - Wambuul Macquarie by ecoPULSE / Kim V. Goldsmith published on 2024-04-06T05:00:25Z Recorded on 1 April 2024 with an Aquarian H2a hydrophone (9m cable) and Zoom F3 from a pedestrian bridge over the Wambuul Macquarie River at Shibble Bridge near Dubbo. This is a regulated inland river. Water flow is controlled by an upstream dam and downstream weirs. On this day, the river was very low, with the water level about 7 metres below the bridge. There's some underwater activity evident, probably fish—most likely invasive European carp, but the dominant sound is the whine of a pump running about 600+ metres downstream. Hundreds of these licensed pumps can be heard on this river, pumping water for stock and domestic purposes and irrigation of crops. Genre Field recording
