The dam supplies drinking water to the towns of Boonah and Ipswich, although the main user is the Swanbank Power Station. It also supplies irrigation water to small crop farms in the Fassifern Valley. SunWater is undertaking a dam spillway capacity upgrade program to ensure the continued safety of the dam. During the 1995 drought dam levels declined to a low of 1% total capacity. The dam reached 100% capacity due to rainfall associated with the 2010–2011 Queensland floods, with water flowing over the spillway for the first time since 1991 on 6 December 2010.
