Title: The Possible effects on migratory fish in the River Dee of increased water abstraction
Author: Water Pollution Research Laboratory
Document Type: Monograph
Annotation: Report for North-East of Scotland Water Board. Report from J.S. Alabaster collection.
This report focuses on the proposed increase of abstraction rate from the River Dee, in 1971, at the Cairntorn intake about 3 miles west of Banchory from 15 mil gal/day (27.8 cusecs) to 20 mil gal/day (37.1 cusecs). The effect of this would be an increase in reduction of flow from 15.8 per cent to 21.1 per cent of the extreme dry-weather flow and from 2.2 per cent to 2.9 per cent of the average flow. Since the river supports migratory fish an attempt has been made on behalf of the Board to assess the likely effect on the fisheries of the increased rate of abstraction, attention being directed mainly at catches on rod and line. The approach adopted is to assume a causal relation between catches and river flow and to use past observations for predictive purposes.
