Emigrant Creek Dam was constructed by Ballina Council in the late 1960’s and was the major water supply for Lennox Head and Ballina until 1988. In 1988 these areas were connected to the Rous Water water supply system. Emigrant Creek Dam remains a key component of the Rous Water regional water supply system and supplements the water supply from Rocky Creek Dam.

Record low levels at Rocky Creek Dam during 2002/03 resulted in Rous Water seeking an emergency water supply source to maintain a reliable supply to it’s customers. An emergency water source was subsequently identified at the Wilson’s River near Howard Grass, downstream of the Boat harbour. During the recent drought period, this source was the principal supply to the majority of Rous Water customers.

The Wilson’s River source is now set to become a key component of the Rous Water water supply strategy.
