The Nerang River rises in the McPherson Range in the Numinbah Valley on the New South Wales and Queensland border and heads north, then east where it flows through and reaching its mouth in the Gold Coast Broadwater at on the Gold Coast and emptying into the Coral Sea. The river descends over its course. Major crossings of the river occur at Nerang where the river is crossed by the Pacific Motorway and at Southport where the river is crossed by the Gold Coast Highway. , 2016 The Nerang River catchment is the largest and most significant river system on the Gold Coast. Its upper reaches in the McPherson Range and Springbrook Plateau deliver flows through significant rural areas and also feed into the Hinze Dam, creating Advancetown Lake, the Gold Coast's main water supply, and Little Nerang Dam. These two reservoirs provide a large percentage of potable water for the Gold Coast and are managed by Gold Coast Water. The Hinze Dam has had a significant flood mitigation effect. In the river's lower catchment, multi-branched canal developments and a number of artificial tidal and freshwater lake systems have influenced and altered large aras of the floodplain. These canal developments provide a range of opportunities for many residents including boating and recreational fishing. The canals and lakes provide habitat to a range of aquatic, terrestrial and marine flora and fauna. The canal systems provide for drainage of stormwater and contribute to flood mitigation, but can periodically be subject to contamination via stormwater drainage. A number of islands are located in the canal region of the river's lower catchment, including the Girung, Paradise, Chevron, Cronin and McIntosh Islands. Two man-made lakes are also located in the lower catchment, including the Lake Rosser and Lake Capabella. The river's mouth was once located much further south. In the early 1800s it entered the ocean at Broadbeach and by 1930 its mouth was located where Sea World now is. The main driving force for this movement is the northward drift of sand along the coast.
Crossings
A number of river crossings of the Nerang River are named, including the following listed below, together with their location relative to tributaries of the river:
Etymology
The river was initially named the River Barrow by government surveyor Robert Dixon when he charted the Gold Coast in 1840, after Sir John Barrow, Secretary of the Admiralty. The surveyor general Thomas Mitchell later changed many places to Aboriginal names, and this included giving the Nerang River its present name. Neerang or neerung are Yugambeh words meaning "little shark" or "shovel-nosed shark". But the local aboriginal people called the river Mogumbin or Been-goor-abee; and the peoples of the Tweed called it Talgai.
Recreation
Surfers Riverwalk
The City of Gold Coast Council is considering investing into the quality and capacity of the Surfers Riverwalk. The route would connect the Gold Coast Highway Bridge crossing of the Nerang River at Main Beach to Pacific Fair Shopping Centre at Broadbeach. The route includes:
Boatramps that are open to the public are located at Waterways Drive at Main Beach, Budds Beach, Evandale, on the Isle of Capri, TE Peters Drive at Broadbeach Waters, Carrara Road, Carrara, and at the Nerang River Parklands.
Nerang Riverkeepers Group
Established in 2000, under the Beaches to Bushland Volunteer restoration program, the group works to restore local endemic species along the Nerang River. A major ongoing project is control of the invasive cats claw creeper, registered as a Weed of National Significance. Cat’s claw creeper was introduced to Australia. It is native to Central and South America and the West Indies. It was first reported as naturalised in the 1950s. The seeds spread by wind or water. A woody vine, it invades warm native forests killing native trees and undergrowth. If cut down it can regrow from persistent underground tubers.
