Avoca Lake, formerly known as Avoca Lagoon and as Bulbararing Lagoon,[3] is an intermittently closed intermediate saline coastal lagoon[1] that is located on the Central Coast region of New South Wales, Australia. Avoca Lake is located between the beachside settlements of North Avoca and Avoca Beach, and adjacent to the east coast, about 85 kilometres (53 mi) north of Sydney.

Features and location[edit]

Avoca Lake is fed by stormwater runoff into Salwater Creek that gathers on the slopes within Kincumba Mountain Reserve to the northwest above Pickets Valley. The lake has a surface area of approximately 0.7 square kilometres (0.27 sq mi) and a catchment area of 10.8 square kilometres (4.2 sq mi).[2] Its outflow is into Bulbararing Bay in the Tasman Sea of the South Pacific Ocean. The outflow is generally closed, and water levels inside the lake are not usually influenced by ocean tides.

Bareena Island lies entirely within Avoca Lake.

Terrigal Lagoon and Wamberal Lagoon are located to the north and are a short distance away.
