flooded by Lake Wyangala waters when construction of the dam was completed in 1935. The Wyangala Station homestead site, which was originally settled by the Newham family, is under the water level and can only be seen when the dam is close to being dry. The small settlement of Wyangala, located downstream of the dam wall, was established to house workers during the dam construction. The current earth and rock wall was constructed between 1961 and 1971 due to fears that the original dam wall was beginning to lift away from its base, and as a result, would not be able to withstand a major flood. The original dam wall can be seen when the water level is around 30 per cent of the reservoir's catchment capacity. In 2008, water entitlements were down to just 10 per cent of normal availability. Some inflows to the reservoir later in the year allowed restrictions for high security licence holders to be relaxed. In late 2009, drought had reduced the water storage level to 4.5 per cent of the reservoir's capacity. The 2022 south eastern Australia floods in late October and early November 2022 resulted in the dam releasing a record /day. The previous record release rate was /day set in 1990.
