Where the Wonboyn River Flows
The Wonboyn River starts when two smaller streams, Narrabarba Creek and Watergums Creek, join together. This happens inside the beautiful Ben Boyd National Park. You can find its starting point east of the Princes Highway and southeast of a place called Kiah. It's about 3 kilometers (1.9 miles) north of Timbillica Hill.
The River's Journey
From its start, the river flows generally towards the east, then northeast, and finally southeast. Along its way, it is joined by one smaller stream, which is called a tributary. The river then flows into a larger area known as Wonboyn Lake.
After passing through Wonboyn Lake, the river reaches its mouth. This is where it meets the Tasman Sea, which is part of the huge South Pacific Ocean. The mouth of the river is located within a bay called Disaster Bay, southeast of Green Cape.
River's Drop in Height
From where it begins to where it meets the sea, the Wonboyn River drops about 44 meters (144 feet) in height. This drop happens over its entire course, which is about 18 kilometers (11 miles) long.
Size and Features of the River
The area of land that collects water for the Wonboyn River is called its catchment area. This area covers about 335 square kilometers (129 square miles).
Water Volume and Depth
The total amount of water in the river and its connected lake is about 9,809 megalitres. A megalitre is a very large amount of water, equal to a million liters! The surface area of the water is about 4.2 square kilometers (1.6 square miles). On average, the Wonboyn River is about 2.7 meters (8.9 feet) deep.
