Upper Exe Catchment 1. INIKGOUCTIGN

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-deterained 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. The 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 Exe catchment.

2. RIVER EXE CATC3MENT

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

The River Exe flows over a distance of 87.2 km from its source to the tidal limit, (Appendix 8.1). Water quality was monitored at fourteen locations on the main river; twelve of these sites were sampled at approximately monthly intervals. Sites at Thorverton and Trews Weir, which are National Water Quality monitoring points, were sampled fortnightly.

Dawlish Water flows over a distance of 9.7 km from its source to the tidal limit, (Appendix 8.1) and was monitored at approximately monthly intervals.

The River Clyst flows over a distance of 25.1 km from its source to the tidal limit in the River , (Appendix 8.1) and was monitored at seven locations.

The Alphin Brook flows over a distance of 11.7 km from its source to tidal limit and was sampled at three locations.

The River Kenn flows over a distance of 14.7 km from its source to tidal limit and was monitored at two locations. (Appendix 8.1).

The Polly Brook flows over a distance of 5.6 km from source to tidal limit and was sampled at one location. (Appendix 8.1).

1 Throughout the Exe catchment eighteen secondary tributaries (plus the Tiverton (Grand Western) and Exeter Canals), fifteen tertiary, six quaternary and one quinary tributary of the River Exe were monitored. In addition Wimbleball Reservoir was sampled at one location at approximately monthly intervals.

The Tiverton Canal (Grand Western) flows over a distance of 18.3 km from its source to the end of the Canal, (Appendix 8.1) and was monitored at two locations.

Samples were collected at monthly intervals for all sites.

2.1 SECONDARY TRIBUTARIES

The flows over a distance of 45.3 km from its source to the confluence with the River Exe, (Appendix 8.1) and was monitored at thirteen locations.

The flows over a distance of 24.3 km from its source to the confluence with the River Exe, (Appendix 8.1) and was monitored at five locations.

The Cranny Brook flows over a distance of 11.4 km before joining the River Clyst, (Appendix 8.1) and was monitored at three locations.

The River Lawman (15.5 km), River Batherm (16.7 km) and (38.8 km) were all monitored at three locations between their source and the confluence with the River Exe, (Appendix 8.1).

The (13.8 km) and (Exe) (14.6 km) were monitored at two locations between their source and confluence with the River Exe, (Appendix 8.1).

The North Brook (6.8 km), River Bu m (8.9 km), Thorverton Stream (6.6 km), Calverleigh Stream (7.0 km), Iron Mill Stream (10.1 km), Brockey River (8.4 km), Grindle Brook (9 km), Aylesbeare Stream (8 km), Pin Brook (6.6 km) and River Quarme (12.3 km) were all monitored at one location. Monitoring points were all located in the lower reaches of these streams. (Appendix 8.1).

2.2 TERTIARY TRIBUTARIES

The River Madford (8.1 km) and Spratford Stream (19.3 km) were all monitored at three locations between their source and confluence with the River Culm. (Appendix 8.1).

The Yeo (Creedy) flows over a distance of 19.6 km before joining the Creedy and was monitored at three locations. (Appendix 8 .1).

The Shuttem Brook flows over a distance of 5.1 km before joining the River Creedy and was monitored at one location. (Appendix 8.1).

2 The River Weaver (12.3 km), Sheldon Stream (9.8 km), Uplowman (6 km), Pulham River (9 km), Danes Brook (12.1 km), Sherdon Water (9.4 km), Jackmoor Brook (7.6 km), Lake (9.6 km), Ford Stream (6.1 km) Binneford Water (8.9 kin) and Holly Water (11.5 km) were all monitored at one location. Monitoring points were located in the lower reaches of these streams. (Appendix 8.1).

2.3 QUATERNARY TRIBUTARIES

The River Troney flows over a distance of 14.1 km before joining the River Yeo (Creedy), (Appendix 8.1) and was monitored at two locations.

Ford Brook (6.6 km), Culvery River (9.4 km), Bolham River (6 km), Heron's Bank Brook (6.7 km) and Dunkeswell Stream (2.8 km) were all monitored at one location. Monitoring points were all located in the lower reaches of these streams.

2.4 QUINARY TRIBUTARIES

The Cole Brook flows over a distance of 5.5 km before joining the River Troney, (Appendix 8.1) and was 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 SYSTEX

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 Exe catchment are identified in Appendix 8.1.

3 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.

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.

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

Ihe 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 (RQO), 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.

Notes (a) Under extrer.e weather conditions (eg flood, drought, freeze-up), or when dominated by plant growth, or by aquatic plant . decay, rivers usually in Class 1, 2, and 3 lay have BODs and dissolved oxygen levels, or amonia content outside the stated levels for those Classes.

Auonia figures are expressed as NH<. t* (c) In most instances the cheiical classification given above will be suitable. However, the basis of the classification is restricted to a finite nuiber of chetiical deteninands and there Bay be a few cases where the presence of a cheaical substance other than those used in the classification aarkedly 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.
