Hydrogeological setting

The well is located on Kilblane Sand and Gravel Formation underlain by Locharbriggs Sandstone Formation near its boundary with the Doweel Breccia Formation (both part of the Appleby Group of Permian age). The Locharbriggs Sandstone is likely to be in hydraulic continuity with the overlying superficial deposits.

Well or borehole construction

The original borehole was 26.6 m deep and there is some uncertainty over the bottom diameter. The borehole was later deepened to 28 m and it has been assumed that this is the only part that is 70 mm in diameter; it is possible that the diameter decreases at the base of the casing.

Hydrograph response

The hydrograph exhibits an annual sinusoidal, but somewhat spiky, response with the water level remaining in the cased out superficial deposits section of the borehole. The minimum water level appears to be controlled, possibly by the river level as the borehole is about 210 m south of Cluden Water.
