Features and location[edit]

Drawing its catchment from within Wallingat National Park and the Wallamba River, Coolongolook River, and Pipers Creek, Wallis Lake has a catchment area of 1,197 square kilometres (462 sq mi) and a surface area of 99 square kilometres (38 sq mi).[2] When full, Wallis Lake covers an area of around 10,000 hectares (25,000 acres),[5] is approximately 25 kilometres (16 mi) long,[3] with a width of 9 kilometres (5.6 mi).[4]

Hadleys Island lies within Wallis Lake, near the confluence of the Wallamba and Coolongolook rivers.

The waterways surrounding Wallis Lake are well known for oyster production.[6]

Lake Wallis was named in honour of James Wallace, a soldier of the 46th Regiment.[4]
