Title: Hampshire Avon catchment management : consultation report : October 1992
Author: National Rivers Authority
Document Type: Monograph
This Consultation Report represents a major step in the production of our first Catchment Management Plan in the Wessex Region. Hampshire Avon catchment lies within three counties, Hampshire, Dorset and Wiltshire, with the largest part in Wiltshire. The river rises in the Vale of Pewsey, and has a geographical catchment area of some 1,701 sq km. Together with two of its tributaries, the Bourne and the Wylye, the Avon drains Salisbury Plain. The River Nadder, which is joined by the Wylye at Wilton, drains the escarpment of the South Wiltshire Downs and the Kimmeridge Clay of the Wardour Vale. The River Ebble and Ashford Water both drain the South Wiltshire Downs and join the Avon just downstream of Salisbury and at Fordingbridge respectively. Below Fordingbridge the catchment area is concentrated on the left bank with a number of significant streams draining the Tertiary deposits of the New Forest. The river drains into Christchurch Harbour where it is joined by the Rivers Stour and Mude before discharging to the sea. The total fall of the river from Pewsey to the sea is 110 metres and the average gradient downstream of Salisbury is approximately 1:1000.
