Rural Municipality of Dufferin #190 was founded in 1913 on January 06, when first meeting was held.
RM of Dufferin covers an area of approximately 380 square miles, a total of 242,212 acres. The municipality is much larger than an average R.M. Running through the extreme south of the R.M.is the QuโAppelle valley, while the Little Arm valley winds through the north side to enter Last Mountain Lake. The roads crossing both valleys have been very difficult to built and many bridges have been constructed. Road and bridge maintenance have been the prime interest of the R.M.Council.
