Additional Information About Place.
The King Edward River lies in the far north Kimberley and is recognised as a wild river. It flows northward for approximately 120 kilometres from its source before turning east. It then turns north again for 100 km to flow into Napier Broome Bay, just downstream of Kalumburu.
The length of the river is 221 km, the drainage area is 8,400 km2. The river has several tributaries: Carson River, Drum Creek, Noolawayoo Creek, Coondillah Creek and Hair Creek. The river was named in 1901 by the geodesist Frederick Brockman during an expedition to this area in honor of the King Edward VII, the ruling monarch at the time. Coordinates of the place submitted for the contest are 14°53’40.7″S 126°12’14.4″ E.
The Department of Water Resources of the Government of Western Australia calls it a “wild” river.
The river flows through an open wooded area with low hills and small rocks. On the bottom there is sand with sandy yellowish red boulders. In the water there are many small stones and a few fallen leaves and bark. In the water and in the shallows, the water is slightly reddish, on the current it is greenish blue. In the river there are small areas with a rapid current, waterfalls and large quiet backwaters. On the banks of the river there are Pandanus aquatic, Melaleuca sp. and various herbaceous plants, including sedges. Therefore, at the bottom there are dead leaves of Pandanus and the bark of the tea tree (Melaleuca).
The water is transparent, visibility is about 2 meters. Average water temperature is 25,7°C. pH is less than 5.0. The total hardness is about 10 ppm. Carbonate hardness is about 18 ppm. It should be noted that KH is slightly higher than GH.
