Smiths Lake, an intermittently closed youthful saline coastal lagoon,[1] is located within the Mid-Coast Council local government area in the Mid North Coast region of New South Wales, Australia. Smiths Lake is located adjacent to the village of Smiths Lake, and adjacent to the east coast, about 274 kilometres (170 mi) north of Sydney.

Features and location

Drawing its catchment from within Wallingat National Park and the Wamwarra and Tarbuck creeks,[4] Smiths Lake has a relatively small catchment area of 28 square kilometres (11 sq mi) and a surface area of 10 square kilometres (3.9 sq mi).[3] When full, Smiths Lake covers an area of around 1,300 hectares (3,200 acres).[5]

Part of the lake shore is a sandbar that separates the lake from the Tasman Sea. When the Mid-Coast Council deems that the lake water level is too high and may cause flooding to low-lying areas around the lake, a trench is constructed from the lake to the ocean using a bulldozer. This releases water from the lake into the ocean and considerably lowers the lake water level.

Due to the nature of Smiths Lake being a coastal dune lake, or coastal lagoon, it was featured in an American documentary about conservation done by producer Elam Stoltzfus.[6]

The most northern of the Ramsar-protected Myall Lakes are located close to the south of Smiths Lake. However, Smiths Lake does not connect nor is formally part of the Myall Lakes. The southern part of Smiths Lake also forms the northern boundary of the Myall Lakes National Park.

Within Smiths Lake there are three islands; Big Island, Little Island, and Bull Island.[4]
