 The County has 912 saline seeps which occupy a total of 4 233ha (10 461 ac). 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.

No outcrop, artesian, canal seepage or natural/irrigation salinity was identified in the County.

As part of the salinity mapping project, permanent water bodies in the County of Flagstaff were sampled for salinity levels.

In the County of Flagstaff, electrical conductivity was measured in 96 water bodies. Fifty-four permanent or semi-permanent water bodies had readings of 8 dS/m or more; the values range from 8 to 50 dS/m. These water bodies should be avoided for watering cattle.
