According to South Australian local government historian Sue Marsden "development of South Australia's South East was greatly helped by drainage schemes. Elsewhere in South Australia the Local Board of Main Roads was the precursor to local government, but in the South East it was district drainage boards." The original South-East Drainage District was formed in April 1876. On 4 June 1914, Mount Muirhead district was annexed by the
District Council of Millicent. The enlarged council area was divided into five wards: Central, Mayurra, Mount Muirhead, Nangula, and
Rendlesham. ==References==
