WSA Davis Creek 2

Observation wells at Davis Creek were completed in November 2020. Four observation wells were installed to investigate the surface and groundwater interaction along the creek to assess baseflow contribution to surface waters. Natural groundwater discharge to the creek has a major influence on the Mountain Sucker habitat. The wells are spaced out laterally and vertically to allow for determination of regional and local gradients near the creek.

WSA Davis 2 was completed to a depth of 24.38 metres. The completion interval straddles the Eastend formation and the silty clay of the Bearpaw formation. The top of the Bearpaw formation is at a depth of 18.9 metres below ground surface. Davis 2 provides information on the water levels and groundwater quality across the interface between the two major regional formations.

The hydrograph for Davis 2 shows water levels ranged between 1098.6 to about 1099.8 metres above sea level. The maximum water level of 1099.8 metres above sea level was reached in the spring of 2021. Minimum water levels of 1098.6 metres above sea level were encountered in late 2020. Annual changes are due to seasonal fluctuations.

Water quality in Davis 2 is of the sodium-bicarbonate type with a sum of ions concentration of 303 mg/L.
