UK Upland Waters Monitoring Network (UK UWMN) site. The Dargall Lane catchment is a sub catchment of Loch Dee, Galloway, south-west Scotland. The catchment rises from 260 m at the sampling station to 716 m at Lamachan Hill. The underlying geology is complicated and includes Silurian and Ordovician greywackes, shales and mudstones, and granite/gneiss intrusions. Rankers are the dominant soil type covering some 80% of the catchment, with peaty podsols and subalpine soils comprising the remainder. The vegetation of this moorland catchment is characterised by Molinia and Calluna. Land-use was traditionally confined to low-intensity sheep grazing. In 2002 however cattle were introduced to a small area, away from the stream, at the bottom of the catchment. Annual rainfall is c. 2400 mm. Note: The area is the size of the catchment.
