WSA Yorkton 93-04

The City of Yorkton is the largest community in Saskatchewan relying on groundwater and utilizes several well fields and aquifers for its municipal water supply.  In order to better understand the aquifers providing the City's groundwater supply the Yorkton Aquifer Management Plan was initiated in the 1990's.  As part this work a number of observation wells were installed and nine of these were incorporated into the network.   

Observation well WSA Yorkton 93-04 was constructed in 1993 to a depth of 41.79 metres near the bottom of buried valley fill in the Logan aquifer system.  The well is located in the City of Yorkton's Logan East well field.  Its purpose is to obtain long-term water level records for the Logan aquifer system and to relate these water level fluctuations to both climate and withdrawals.

Water levels for WSA Yorkton 93-04 show a very similar pattern to those in WSA Yorkton 93-03, but are slightly lower indicating a downward hydraulic gradient.  The water level minimum of 495.4 metres occurred in 2003 while the maximum water level peak of just over 500.5 metres occurred in 2011.  

Water from WSA Yorkton 93-04 is of the calcium-bicarbonate/sulphate type and has a total dissolved solids concentration of about 1190 mg/L.
