The main purpose of the dam is for potable water supply of the Gold Coast region.[3][2] The impounded reservoir is also called Little Nerang Dam. The dam was closed to the public in 2013 due to safety concerns.[4] Location and featuresThe dam is located {{convert|9|km}} west of {{QLDcity|Tugun}} and {{convert|25|km}} driving distance from {{QLDcity|Mudgeeraba}}, and is located directly upstream from the Hinze Dam. Prior to the completion of the Hinze Dam, the Little Nerang Creek Gravity Scheme supplied the water requirements of the Gold Coast area. Water flows by gravity pipeline to the Mudgeeraba Water Treatment Plant. The plant, completed in 1969, has the capacity to treat {{convert|110|ML|impgal USgal}} a day. The water then flows by gravity to the city's storage reservoirs. Completed in 1962,[3] the rock and earthfill dam structure is {{convert|44|m}} high and {{convert|201|m}} long. The {{convert|68|e3m3|adj=on}} dam wall holds back the {{convert|8390|ML|impgal USgal|adj=on}} reservoir when at full capacity. From a catchment area of {{convert|35|km2}} that includes the Springbrook Plateau, the dam creates an unnamed reservoir with a surface area of {{convert|50|ha}}. The uncontrolled un-gated spillway has a discharge capacity of {{convert|570|m3/s}}.[3] Initially managed by Gold Coast Water, management of the dam was transferred to Seqwater in July 2008. RecreationalRecreation is not permitted at Little Nerang Dam. See also
