 The M.D. of Provost has 1 851 saline seeps which occupy a total of 16 099.20 ha (39 768 ac), representing 4.3% of the M.D.'s total area. The visibly saline areas have such high salinity levels that annual crops cannot be grown and forage crops have significantly reduced yields. Often the lands surrounding the visibly saline areas are also weakly saline, resulting in reduced yields especially for salt-sensitive crops.

Depression bottom salinity is occupies the greatest area (85.8% of all saline land in the M.D.), followed by coulee bottom salinity (9.8%), contact/slope change salinity (4.2%), outcrop salinity (0.2%) and artesian salinity (0.009%). There is no evidence that slough ring salinity occurs in the M.D. Also, there are no irrigated lands in the M.D., thus there is no irrigation-related salinity.
