Title: River Axe Fish Study - Stage 2, Environmental Assessment for River Abstraction
Author: J.S. Alabaster
Document Type: Monograph
Annotation: J.S. Alabaster collection
Abstract:
A study has already been made of the relation between fish catches in the R. Axe and river flow, together with an evaluation made of the likely effect on catches of water abstraction at Whitford down to a minimum residual value of 0.625 m3/s (Alabaster, 1986).
A further report (Alabaster, 1987) considered: 1) the effect of abstraction below that minimum in the R. Axe, 2) the minimum that might be appropriate in the R. Coly and 3) the likely effect on the tributaries of augmentation of the flow using groundwater.
In addition, an opinion on the impact of water abstraction on estuarine water quality has been given (letter of 2 July, 1987; Appendix I) and the implications of setting a minimum as the 95%ile exceedance value for all rivers in the area of the South West Water Authority (SWWA) have been briefly discussed (Note of 6/2/1989; Appendix II).
The present assessment elaborates further on these and related matters and should be read in conjunction with the earlier documents referred-to.
