Wyangala dam on the Lachlan River was built between 1929 and 1935 and is used for irrigation, flood mitigation and water supply for the large town of Cowra 20 kilometres west.
At the foot of the dam wall there is a substantial village with houses (some I assume are weekenders), church, conference centre, school, community hall and country club with 9 hole golf course, tennis courts and lawn bowls. At the dam itself there is a large number of cabins and camping spots to the whole area has a holiday feel about it. An information centre, kiosk and petrol station serve the campers and local community.
Apparently there was an older village of Wyangala lost under the waters of the dam.
