Explanatory note
(This note is not part of the Regulations)
These Regulations prescribe a system for classifying the quality of inland waters which need protection or improvement in order to support fishlife.
The classifications SW (“salmonid waters”) and CW (“cyprinid waters”) reflect the mandatory values assigned by Directive 78/659/EEC (on the quality of fresh waters needing protection or improvement in order to support fishlife) to the parameters listed in the Schedule to these Regulations.
The Regulations also incorporate the reference methods of measurement, and the minimum frequency required for sampling and analysis, laid down in that Directive for those parameters.
The Regulations, together with the Surface Waters (Fishlife) (Scotland) Directions 1997, transpose Directive 78/659/EEC.
Copies of the Surface Waters (Fishlife) (Scotland) Directions 1997 may be obtained from the Environment Protection Unit, Scottish Office Agriculture, Environment and Fisheries Department, Victoria Quay, Edinburgh EH6 6QQ.
