The Moogerah Dam is a mass concrete double curvature arch dam with an un-gated spillway across the Reynolds Creek that is located in the South East region of Queensland, Australia. The main purposes of the dam are for irrigation of the Reynolds Creek and for supply of potable water to Warrill Creek and farmers in the Warrill Valley. The impounded reservoir is called Lake Moogerah. Moogerah is derived from the Aboriginal word Moojirah, meaning "home of the thunderstorm." Location and features The dam is located above the Fassifern Valley, approximately southwest of Ipswich. Aratula is the nearest town, approximately from the dam and the nearest major centre is . The primary inflow of the reservoir is the Reynolds Creek, a tributary of the Bremer River. Construction on the dam began in 1959, although land for the project was resumed as early as 1916. Completed in 1961 as the central catchment of the Warrill Valley Water Supply Scheme, the concrete dam structure is high and long and allows access to Mount Edwards in Moogerah Peaks National Park. The dam wall holds back the reservoir when at full capacity. From a catchment area of that includes much of the northeastern slopes of the Main Range, the dam creates Lake Moogerah, with a surface area of . The uncontrolled spillway has a discharge capacity of . Initially managed by SunWater, management of the dam was transferred to Seqwater in July 2008 as part of a water security project in the South East Queensland region, known as the South East Queensland Water Grid. 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. Recreation Amenities adjacent to the dam and reservoir include such places as Moogerah Lakeside Bush Retreat which was previously a church campground but is now a locally owned and operated lakeside camping destination offering standard camping options as well as bunkhouses sleeping up to 12 people
