The ward was created in 1999 and elected one councillor using the first-past-the-post voting electoral system.
The ward was a Labour stronghold as the party successfully held the seat at every election.
George Smith was the only councillor elected as he represented the ward from 1999 to 2007.
In 2007, the ward was abolished and replaced by the multi-member Ballochmyle ward as council elections moved to a proportional voting system – the single transferable vote – following the implementation of the Local Governance (Scotland) Act 2004.
The ward centered on the villages of Catrine and Sorn as well as the eastern part of Mauchline and took in an area in the east of East Ayrshire next to its border with South Lanarkshire.
