 The M.D. of Cardston has 1370 saline seeps which occupy a total of 6 607 ha (16 299 ac), representing 1.3% 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 occupies the greatest area (41.0% of all saline land in the M.D.), followed by contact/slope change salinity (25.7%), coulee bottom salinity (11.9%), natural/irrigation salinity (11.6%), irrigation canal seepage salinity (5.4%), outcrop salinity (4.1%), and artesian salinity (0.3%). There is no evidence that slough ring salinity occurs in the M.D.
