Lake Moogerah, formed by Moogerah Dam, is a water supply and irrigation dam on Reynolds Creek, a tributary of the Bremer River in Southeast Queensland's Fassifern Valley. The lake is used for recreation, fishing and camping. "Moogerah" comes from the aboriginal word Moojirah meaning home of the thunderstorm. The lake is located around 60 km southwest of Ipswich and about 90 minutes drive from Brisbane. Aratula is the nearest town, about 11 km from the lake.
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.
