Hydrogeology of the Gleichen Area, Alberta

The hydrogeology of the uppermost 1000 feet (about 300m) of strata in the Gleichen area is described. Maps and profiles were constructed from existing data and from data collected by a field survey and drilling and testing operations. The 20-year safe yields range from 1 igpm (about 5 l/min) to more than 100 igpm (about 450 l/min). The best aquifers are Quaternary sands and gravels and Upper Cretaceous Belly River sandstones.

Water quality varies: total dissolved solids range from less than 1000 to more than 5000 ppm, and the general chemical character of the water varies from Ca/HCO3 type to Na/SO4 type. In the deep Milk River sandstones in the southeast corner of the map area Na/Cl type waters are present.
