Author: National Rivers Authority
Document Type: Monograph
A detailed biological survey of the R.Lark in the vicinity of Lee Brook, Isleham was carried out in July 1989 to assess the likely impact of the discharge of saline water from Isleham Water Treatment Works denitrification plant. The survey work included mapping the occurrence and distribution of the macrophytes and the collection to benthic invertebrate samples. In October 1990 a second survey for the benthic invertebrates was carried out, following commissioning trials of the denitrification plant, which had occurred that summer, Following one years operation of the denitrification plant, macrophyte and benthic invertebrate surveys were repeated in August 1991. This report gives observations on the impact of the discharge on the ecology of the river.
