Winburndale Dam, Gravity dam in Central Western New South Wales, Australia.

Winburndale Dam is a concrete gravity structure that crosses the Winburndale Rivulet in Central Western New South Wales. The construction holds water in a reservoir situated at high elevation and serves multiple water supply functions for the surrounding region.

Construction of Winburndale Dam began in 1931, after lengthy investigations into possible dam sites, and was paid for with Unemployment Relief funds during the Great Depression. The scheme included a 21-kilometre gravity-fed wood stave pipeline running from the dam to Bathurst. The sources give no completion date.

The dam is not in the Murray-Darling basin; it draws from the Winburndale Rivulet, an 88-square-kilometre catchment, and supplied raw water to Bathurst for parks and industry. Its construction also involved a 21-kilometre gravity-fed wood stave pipeline to the city.

The dam lies 19 kilometres east of Bathurst, inside the Winburndale Nature Reserve, and public access to the dam is prohibited, so it cannot be visited on foot. The 21-kilometre wood stave pipeline that once carried water to Bathurst was built as part of the works. The surrounding country is almost uninhabited, with fewer than two inhabitants per square kilometre.

Public access to Winburndale Dam is prohibited, so the reservoir and its fish cannot be visited by anglers. The dam lies inside Winburndale Nature Reserve, 19 kilometres east of Bathurst, and the surrounding area is almost uninhabited, with fewer than two residents per square kilometre.
