1. INTRODUCTION

Monitoring to assess the quality of river waters is undertaken in thirty-four catchments within the region. As part of this monitoring programme samples are collected routinely from selected monitoring points at a pre-determined frequency per year, usually twelve spaced at monthly intervals. Each monitoring point provides data for the water quality of a river reach (in kilometres) upstream of the monitoring point.

Each water sample collected from each monitoring point is analysed for a range of chemical and physical constituents or properties known as determinands. Hie analytical results for each sample are entered into a computer database called the Water Quality Archive.

Selected data are accessed from the Archive so that the quality of each river reach can be determined based on a River Classification System developed by the National Water Council (NWC), (7.1).

This report presents the river water quality classification for 1991 for monitored river reaches in the River Tamar catchment.

2. RIVER TAMAR CATCHMENT

For reasons of clarity the following monitoring summary is not broken up into four separate sub-catchments of the River Tamar as represented by the Water Quality Maps attached.

The River Tamar flows over a distance of 78 km from its source to the tidal limit, (Appendix 8.1). Water quality was monitored at sixteen locations on the main river; fourteen of these sites were sampled at approximately monthly intervals. The site at Gunnislake, which is a National Water Quality monitoring point, was sampled fortnightly.

Throughout the Tamar catchment eighteen secondary, ten tertiary, four quaternary and two quinary tributaries of the River Tamar were monitored at approximately monthly intervals.

In addition Upper and Lower Tamar lakes were monitored each at one location and approximately monthly intervals.

2.1 SECONDARY TRIBUTARIES

The River Inny flows over a distance of 32.5 km from its source to the confluence with the River Tamar, (Appendix 8.1) and was monitored at eight locations.

The River Ottery flows over a distance of 33 km from its source to the confluence with the River Tamar, (Appendix 8.1) and was monitored at six locations.

The River Kensey and Carey flow over a distance of 16.8 km and 21.5 km respectively from their source to the confluence with the River Tamar, (Appendix 8.1) and were monitored at five l o c a t i o n s .

1 The River Lyd flows over a distance of 25.2 km from its source to the confluence with the River Tamar, (Appendix 8.1) and was monitored at four locations.

The Lowley Brook (10.1 km), River Claw (12.1 km) and River Deer (16.8 km) were all monitored at three locations be tween, their source and the confluence with the River Tamar, (Appendix 8.1).

The Small Brook (9.1 km), Lamberal Water (9.6 km) and the River Luckett (5.7 km) were all monitored at two locations between their source and confluence with the River Tamar, (Appendix 8.1).

The Derrill Water (7.4 km), Blanchdown Stream (0.7 km), Portontown Stream (6.4 km), Latchley Brook (1.9 km), Dameral Stream (5.5 km), Tala Water (9.5 km) and Lana Lake (4.9 km), were all monitored at one location. Monitoring points are all located in the lower reaches of these streams. (Appendix 8.1).

2.2 TERTIARY STREAMS

The River Thrushel flows over a distance of 21.4 km before joining the River Lyd, (Appendix 8.1) and was monitored at four l o c a t i o n s .

Penpont Water flows over a distance of 15 km from its source to the confluence with the River Inny, (Appendix 8.1) and was monitored at three locations.

The River Lew and Caudworthy Water flow over a distance of 15.8 km and 11.7 km respectively from their source to the confluence with the River Ottery, (Appendix 8.1) and were monitored at two lo c a t i o n s .

The Tregeare Stream (3.8 km), Canworthy Water (5.2 km), Bolesbridge Water (9.9 km), Henford Water (5.5 km), Colesmill Stream (3.5 km) and Quither Brook (6.7 km) were all monitored at one location. Monitoring points are all located in the lower reaches of these streams. (Appendix 8.1).

2.3 QUATERNARY TRIBUTARIES

Combebow Stream flows over a distance of (5.5 km) and was sampled at one site between its source and confluence with the River Lew. (Appendix 8.1).

Breazle Water (5.7 km) and Bratton Brook (6.1 km) were both sampled at one location between their sources and confluence with and River Thrushel. (Appendix 8.1).

The River Wolf flows over a distance of 14.9 km from its source to the confluence with the River Thrushel, (Appendix 8.1) and was monitored at three locations.

2 2.4 QUINARY TRIBUTARY

The Broadwood Brook and Hennard Stream flow over a distance of 6.3 km and 4.2 km respectively from their source to the confluence with the River Wolf, (Appendix 8.1) and were monitored at one location.

Each sample was analysed for a minimum number of determinands (Appendix 8.2) plus additional determinands based on local knowledge of the catchment. In addition, at selected sites, metal analyses were carried out.

The analytical results from all of these samples have been entered into the Water Quality Archive and can be accessed through the Water Resources Act Register, 7.2).

3. NATIONAL WATER COUNCIL'S RIVER CLASSIFICATION SYSTEM

3.1 River Quality Objectives

In 1978 River Quality Objectives (RQOs) were assigned to all river lengths that were part of the routine monitoring network and to those additional watercourses, which were not part of the routine network, but which received discharges of effluents.

For the majority of watercourses long term objectives were identified based on existing and assumed adequate quality for the long term protection of the watercourse. In a few instances short term objectives were identified but no timetable for the achievement of the associated long term objective was set.

The RQOs currently in use in the River Tamar catchment are identified in Appendix 8.1.

3.2 River Quality Classification

River water quality is classified using the National Water Council's (NWC) River Classification System (see Appendix 8.3), which identifies river water quality as being one of five quality classes as shown in Table 1 below:

Table 1 - National Water Council - River Classification System

Class Description

1A Good quality IB Lesser good quality 2 Fair quality 3 Poor quality 4 Bad quality

Using the NWC system, the classification of river water quality is based on the values of certain determinands as arithmetic means or as 95 percentiles (5 percentiles are used for pH and dissolved oxygen) as indicated in Appendices 8.4 and 8.4.1.

3 The quality classification system incorporates some of the European Inland Fisheries Advisory Commission (EIFAC) criteria (Appendix 8.3) recommended for use by the NWC system.

4. 1991 RIVER WATER QUALITY CLASSIFICATION

Analytical data collected from monitoring during 1989, 1990 and-1991 were processed through a computerised river water quality classification programme. This resulted in a quality class being assigned to each monitored river reach as indicated in Appendix 8.5.

The quality class for 1991 can be compared against the appropriate River Quality Objective and previous annual quality classes (1985-1990) also based on three years combined data, for each river reach in Appendix 8.5.

The river water classification system used to classify each river length is identical to the system used both in 1985 and 1990 for the Department of the Environment's Quinquennial River Quality Surveys. The determinand classification criteria used to determine the annual quality classes in 1985, subsequent years and for 1991 are indicated in Appendices 8.4 and 8 . 4.1.

River water quality has been classified annually using a set of class standards, which includes a standard of 25 mg/1 for suspended solids (as an annual mean). This standard is incorporated in the Class 1A, IB and 2 classification criteria, being applicable to both salmonid and cyprinid fish. (7.3).

If this suspended solids standard has been exceeded in the annual classification at any monitoring location, then the quality of the river reach above the monitoring location is said to have failed to meet its objective and associated use, i.e. the protection of salmonid and cyprinid fish.

This would result for the suspended solids quality test in classifying the river reach as being Class 3 - poor quality.

The type of quality downgrading affects locations across the region, the River Tamar is one such example.

The river quality classes for 1991 of monitored river reaches in the catchment are shown in map form in Appendix 8.6.

The calculated determinand statistics for pH, temperature, dissolved oxygen, biochemical oxygen demand (BOD), total ammonia, un-ionised ammonia, suspended solids, copper and zinc from which the quality class was determined for each river reach, are indicated in Appendix 8.7.

4 5. NON-COMPLIANCE WITH QUALITY OBJECTIVES

Those monitored river reaches within the catchment, which do not comply with their assigned (KQO), are shown in map form in Appendix 8.8.

Appendix 8.9 indicates the number of samples analysed for each' ' - determinand over the period 1989 to 1991 and the number of sample results per determinand, which exceed the determinand quality standard.

For those non-compliant river reaches in the catchment, the extent of exceedance of the calculated determinand statistic with the relevant quality standard (represented as a percentage), is indicated in Appendix 8. 10.

However, the basis of the classification is restricted to a finite nunber of chenical determinands and there nay be a few cases where the presence of a chenical substance other than those used in the classification narkedly reduces the quality of the water. In such cases, the quality classification of the water should be down-graded on the basis of biota actually present, and the reasons stated.
