 Kneehill County has 662 saline seeps which occupy a total of 2,210 ha (5,462 ac), representing about 0.65% of the county'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 largest proportion of the County's saline area (25.1% of the total saline area), followed by contact/slope change salinity (23.3%), outcrop salinity (23.1%), coulee bottom salinity (22.9%), and artesian salinity (5.6%). There are many small contact and slope change seeps, and fewer but larger depression bottom and coulee bottom seeps.
