Author: National Rivers Authority South West Region
Document Type: Monograph
Abstract:
5 sites on the West Okement and Okement rivers were sampled before and after drought of 1989 broke. The discharge of Meldon Quarry stream was found to cause a severe reduction in both numbers and diversity of the aquatic fauna before and after the drought broke. There is no evidence that severe acid conditions occured at any of the other sites investigated.
