Crump weir (15.9m broad) equipped with pressure tapping (not used) & d/s recorder. Cableway installed in 1999; susequently removed. Some subsidence: fall of 41mm across the weir crest. Modular up to 24 cumecs and all but highest flows contained. Bypassing above 29 cumecs, hence flood flows may be underestimated. Little net impact of abstractions and discharges (minor contribution to Kennet & Avon canal) but augmentation from WBGS during droughts. High baseflow component but responsive contribution from the R. Enbourne. Dmfs 04-24/12/98 estimated by NRFA (using 39103) due to gauging hut refurbishment.
A mainly pervious catchment (Chalk with significant Drift cover), but the lowest quarter is largely impermeable. A primarily rural catchment with scattered settlements (Newbury is the largest town); significant urban growth along the Kennet valley.
