The land along the river is estimated as being 83% cleared yet the water quality is generally healthy fresh water. The salinity level of the King River at discharge is 800 mg/L.[3]
History
The river was named after an early explorer of the Australian and Patagonian coasts, Phillip Parker King, by Thomas Braidwood Wilson while exploring the region in December 1829.[4]
The estuarine zone of the river is from the mouth to 7 kilometres (4 mi) upstream to where Mill Brook joins the river.
The area around Lower King was a known haunt for sealers in 1831.[5] It was settled later in the 1830s but the townsite was not gazetted until 1959.[6]
The Lower King River Bridge was constructed in 1898 and washed away during a storm in 1900. Both the upper and lower bridges were damaged during storms in 1902. In 1944 and 1947 parts of the lower bridge collapsed and rebuilt.[5]
In January 2019 the Upper King Bridge was burned by a deliberately lit fire[7] causing A$300,000 in damage.[8]
Tributaries
The main tributary of the King River is Mill Brook which joins the King about 2 kilometres (1.2 mi) north-west of the Upper King Bridge.
