Author: N.A. Reader
Document Type: Monograph
Abstract:
Fish surveys were carried out in the River Okement prior to and following a fish mortality on 16th. September 1989. The results indicate that there was a total mortality of salmonid fish over a 14.1km. stretch of the Rivers Okement and West Okement. The total loss of all age groups of salmonids is calculated to be in the order of 110,000 fish. The exact point at which the fish kill commenced is difficult to define in relation to known discharges into the West Okement.
