Elizabeth River flows into Darwin Harbour close to Darwin in the Northern Territory of Australia. It is a traditional waterway of the Larrakia people.

Course

The headwaters of the river rise south of Noonamah and flow in a northwesterly direction and cross the Stuart Highway south of Humpty Doo. It continues through an estuarine area and discharges into the East Arm of Darwin Harbour, then into Beagle Gulf, and eventually into the Timor Sea.

The river shares a catchment area with the Finniss and Howard Rivers; the combined watershed occupies an area of 8672 km2.

Climate

The climate of the Elizabeth River region is monsoon tropical with two distinct seasons: dry and wet. The dry season lasts for six months between April and September with an average rainfall of 24 mm, whereas the wet season lasts between October and March with an average monthly rainfall of 254 mm per month. The majority of the rain falls between December and April. Runoff varies between 250–1000 mm.

Peak flow for the Elizabeth River occurs in February with 389 ML per day, after which it slowly decreases until July, when there is no freshwater input into Darwin Harbour until the onset of the following wet season. Cyclone frequency is low to moderate.

The Finniss, Elizabeth and Howard Rivers have a mean annual outflow of 3000 GL,

Water quality

The water quality was excellent at the upper estuary monitoring sites of the Northern Territory Government in 2011. Water quality at the freshwater monitoring sites was very good in 2011.

Geology

The underlying lithology is dominated by Permian siltstones and sandstones.
