Title: Non-compliance with water quality objectives on the Croyde stream (upper catchment)

This report is concerned with determining the cause of high Biochemical Oxygen Demand (BOD) levels in the Croyde Stream, identified from the routine water quality monitoring data at Forda (URN: R30A031, NGR SS457391) (Map 1). Water quality problems between Croyde and Georgeham were addressed in an earlier report (FWI/93/016). The upper catchment covers an area of approximately 3km2 and is mainly given over to grazing. The stream is reasonably fast flowing, descending 70m over the 2km between the source and Forda. The Water Quality Objective for the Croyde Stream is River Ecosystem Class 2 (RE2). During the period 1993-5 (inclusive) the Croyde Stream between Crowborough and Forda marginally failed RE2 objectives because of elevated Biochemical Oxygen Demand (BOD) values (see Ref 1 for explanation of significant/marginal failures). These failures were identified in ' Local Environment Agency Plan, North Devon Streams, October 1996', where it was stated that further work would be carried out. This document details the methods and results of such work.
