 The Blood Indian Reserve has 384 saline seeps which occupy a total of 1 833 ha (4 529 ac), representing 1.3% of the Reserve'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.

Contact/slope change salinity occupies the greatest area (46.5% of all saline land on the Blood Reserve), followed by outcrop salinity (32.5%), depression bottom salinity (14.6%), coulee bottom (4.5%), irrigation canal seepage (1.3%), artesian (0.3%) and slough ring (0.3%). There is no evidence that natural/irrigation salinity occurs on the Reserve.
