WSA Hague

Observation well WSA Hague was constructed to observe natural groundwater level fluctuations in an intertill aquifer and to relate these variations to changes in climate and variations in the water level of the South Saskatchewan River. The well was completed in 1966 to a depth of 49.68 metres into medium to coarse grained sand of an intertill aquifer. The Saskatchewan Research Council concluded that the aquifer is hydraulically connected to the river to which it discharges. They also noted that changes in the well are tied to changes in the river stage.

The record low water level of about 462.7 metres for WSA Hague occurred in 2004. This low water level was the result of sharp downward spike that was at least a metre lower than any other level on the hydrograph and may have been from an unknown pumping source. Following this decline, water levels recovered somewhat but remain below the levels seen in the 1970’s. The highest peaks on the hydrograph of about 465.6 metres occurred in 1971 and 1976.

The well yields water of the sodium-sulphate type and has a Total Dissolved Solids of approximately 2870 mg/L.
