Title: Conwy catchment management plan : water quality assessment technical memorandum
Author: M. Heller
Document Type: Monograph
Catchment Management Plans consider the uses to which the water resource in a catchment is put. From these uses objectives are derived. The water quality required to achieve these objectives and protect the uses are defined by water quality standards which are mostly quantifiable so that achievement of the objectives may be readily assessed. The Catchment Management Plans summarise this information in a very succinct form so that conflicts of use and failure of objectives may be easily identified. This report is a supporting document to the plan and is a record of the water quality data used in that part of the assessment carried out by the Environmental Appraisal Unit. For the Conwy Catchment, the plan also incorporates as a pilot study, the application of proposed Statutory Water Quality Objectives (SWQOs). The SWQO scheme applies only to classified river stretches in respect of Fisheries Ecosystem Use and future Potable Abstraction Use. The assessments described in this report was carried out in two parts which involved different sampling points and techniques of data analysis: 1) For the production of the Catchment Management Plan and 2) For the proposed SWQOs. The assessment described in this report is confined to the river above the tidal limit.
