 Special Area 2 has 737 saline seeps which occupy a total of 7 601 ha (18 783 ac), representing about 0.78% of the municipality'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.

Coulee bottom salinity occupies the greatest area (62.7% of all saline land in Special Area 2), followed by depression bottom salinity (33.1%), outcrop salinity (3.2%), contact/slope change salinity (1.0%) and artesian salinity (0.01%). There is no evidence of slough ring salinity in Special Area 2, and there is no irrigation.
