Hydrogeology of the Tawatinaw Area, Alberta

The drift is the water-bearing zone in most of the Tawatinaw area except for the southwest and the south-central part of the map area, where wells obtain water from the Wapiti Formation. The yields range from less than 1 igpm (imperial gallon per minute) to 50 igpm at a maximum. In the northeast the drift is very fine grained and clayey, and as the Lea Park shales underlie the area the yields will not be more than 5-10 igpm.

Water quality is usually good. The waters are calcium bicarbonate with low sulfates and chlorides. In the more settled southeastern corner of the map area nitrate contents become significant.
