Flow Duration Curve for Gauged Daily Flows

Station Description

Velocity-area station with natural channel control on a straight, stable reach. Replaced earlier station at Barrasford. Predominantly natural regime but affected by Kielder releases (see 23022) - including pulsed hydropower releases; overall impact most evident at low flows. Catcleugh and Colt Crag Reservoirs in catchment (also intermittent abstraction at Barrasford) - net export of water.

Catchment Description

Upland catchment, mainly on formations of the Carboniferous L'st Series. Overlain by 50% Boulder Clay cover and peat in headwaters. Rugged moorland and upland pasture, with 30% forest cover (in W of catchment).
