It was created by redistribution in 1999, with territory from Lakeside, Morris, and the now-defunct riding of Gladstone.
It was bordered to the north by Portage la Prairie, to the west by Turtle Mountain, to the east by Morris, and to the south by Pembina and Emerson.
It included the communities of Carman, Somerset, Treherne, St. Claude, Notre Dame de Lourdes, Miami and Elm Creek.
Sixteen per cent of Carman's residents are francophone, the fourth-highest total in the province.
For the 2011 election, Carman was dissolved into Portage la Prairie and the newly created riding of Midland.
