Researching this River was interesting. The South Australian Nomenclature Act 1917 authorised the compilation of place-name changes deemed to be of enemy origin. On 10 January 1918 some 69 name changes were gazetted. The Nomenclature Act 1935 restored the former names of 2 towns (Hahndorf and Lobethal) and 1 Adelaide suburb (Klemzig). Around 20 other names were reverted in the 1970s and 1980s.
Rhine Villa was renamed Cambrai in 1918.
Rhine River South was changed to The Marne in 1918, then changed to Marne River in 1971.
Rhine River North was renamed The Somme in 1918, then changed to Somme Creek in 1971.
A popular online mapping tool has a mixture of these River/creek names, so might be confusing if you try to locate these.
Rhine River North unfortunately does not make this list, as it is officially now named Somme Creek which starts at S34.50993 E139.15871 just east of Keynton Road halfway between Keynton and Moculta. It flows in a southerly direction parallel and just east of Jutland Road. It merges with Marne River at S34.66367 E139.18854. Its course is around 25km.
