A large pool on the Deua River, the freshwater reaches of the Moruya River, during a period of higher flows.

The Deua River is the freshwater reaches of the Moruya River, an east coast drainage in southern New South Wales, Australia. The Deua River rises in rugged and thickly forested ranges south of Braidwood. This catchment is in a rain shadow, so the Deua River is on the whole a small river, and naturally experiences periods of very low flow. The village of Araluen lies in the valley of Araluen creek, that joins the Deua River at roughly the mid point in its course. The name 'Araluen' is reputed to mean 'water lilly' or 'place of the water lillies' in the local aboriginal dialect. At the time of European settlement Araluen was described as a broad alluvial valley with many natural billabongs covered with water lillies. Unfortunately, no such billabongs exist in the Araluen valley today. As with most river and creek valleys in south-eastern Australia, the natural landscape of Araluen Creek and its valley were completely destroyed by rampant and extremely destructive gold mining in the latter half of the 1800s. This has mobilised thousands of tons of coarse granitic sands and lead to serious sand-slugging or sand siltation of the lower half of the Deua River below the Araluen Creek confluence. Nevertheless the Deua River supports valuable populations of the threatened Australian grayling and several other native freshwater fish species.
