The rivers, lakes, estuaries and coastal waters o f Wales are subject to large and rapidly increasing demands from the users o f water. Many different uses interact, or compete for water or water space, and inevitably come into conflict with one another. The National Rivers Authority (NRA) is the major manager o f the water environment in England and Wales and aims to harmonise conflicts between competing water users as well as its general duties that include:

• Maintenance and improvement of water quality by control of pollution in surface and groundwater.

• Flood defence for people and property.

• Flood warning.

• Management of water resources.

• Maintenance and improvement of fisheries.

• Conservation of the natural water environment.

• Promotion of water based recreation.

• Navigation (in some rivers).

The NRA believes it can only carry out its work by adopting the concept ol integrated catchment management. This means that a river catchment is considered as a whole and the actions in each of our areas of responsibility must take account o f the possible impact on the other areas.

We have decided to formally present our catchment management policies to the public via Catchment Management Plans which will be produced for all the rivers in Wales by 1998. The Plans are intended to provide a link between us and the users of water in each catchment so that we can better reflect their interests whilst carrying out our duties. For this reason each Plan includes a Consultation Phase during which the general public are invited to comment on our proposals for the future management of the catchment.

aaAOOdin 9 vh» Njwiaawv FLOOD DEFENCE

Flood defence activity within the catchment is concentrated on the maintenance of tidal and fluvial defences, main river watercourses and adopted ditches.

The low lying Malltraeth Marsh is the only extensive area threatened by tidal inundation within the catchment. The area at risk is an Internal Drainage District (IDD), known as Malltraeth Marsh IDD.

Elsewhere in the catchment flood defence work consists mainly of deweed/desilt and river management schemes carried out when and where necessary. There are no major main river flooding problems where property is affected, although the agricultural flood plains are inundated from time to time. There are, however, a few isolated cases o f flooding to properties associated with non- main rivers within the catchments.

Water Level Management Plans will be drawn up for all sites agreed between us and the Countryside Council for Wales. A three year prioritised programme for the production o f these plans will be undertaken.

Flood defence is one of the important considerations in the planning process and we will be actively involved in liaison regarding any proposed development or proposed allocation for development in sensitive areas.

Sea defences on the rugged coastline RECREATION

The island is popular with holiday makers and water- based activities such as yachting and pleasure boating are major attractions. Windsurfing is enjoyed all around the coastline and the number o f participants is on the increase.

Anglesey has many bathing beaches on all sides o f the island. 26 beaches are subject to local authority Launching canoes from the slipway at Menai Bridge sea shore and sea side pleasure boat byelaws. This excludes certain boating activities between the 1st April and the 30th September each year. Amongst the most popular o f the beaches are Benllech, Red Wharf Bay, Trearddur Bay, Rhosneigr and Llanddwyn. The waters of Benllech, Trearddur Bay and Rhosneigr have been identified under the EC Bathing Waters Directive (76/160/EEC) and all currently com ply with the standards in the Directive.

The coastal section o f Anglesey is largely designated AONB (part Heritage Coast) and is of high amenity value, particularly for walking and birdwatching. Facilities for birdwatchers have been developed at Holyhead Country Park, South Stack, Llyn Alaw, Malltraeth and Newborough. Wildfowling occurs on the estuaries o f the Cefni and N odw ydd and in the Cymyran Straits.

Ynys Mon Borough Council is currently developing a coastal footpath network, linking areas of settlement with the coast. In contrast, riverside access is largely absent though there is continuous access to the Afon Cefni for 10km from Llangefni to Malltraeth. Footpaths are common in the vicinity of lakes and reservoirs but patchy on wetlands.

Apart from the sites at Alaw and Cefni reservoirs and Newborough Warren picnic sites have not been widely developed on the island.

H13VNMQV) CONSERVATION

The ecological importance of Anglesey is reflected in the designation of the entire island as an Environmentally Sensitive Area (ESA). Over 7,500 hectares are within Sites o f Special Scientific Interest (SSSI), 1574 hectares of which have been designated as National Nature Reserve (NNR). In addition, there are 21,497 hectares of Areas of Outstanding Natural Beauty, 31 miles of Heritage Coastline, 4 candidate Special Areas o f Conservation and 1 Special Protection Area.

Wetlands form a relatively high proportion o f protected sites with base-rich fen communities predominant in the east and, acid fens prevalent on the west of the island. However river and wetland bird populations are poor and species such as kingfisher, dipper and common sandpiper are restricted by habitat and geomorphology, whilst wet grassland species such as lapwing, snipe and redshank continue to decline.

The quality o f riparian habitat is also generally poor, most main rivers are regularly maintained, lack trees and adjacent land is often improved to the water's edge. The absence of a river corridor is significant across much o f Anglesey, and has undoubtedly played a part in the decline of the otter which is no longer to be found on the Island.

Aberffraw Estuary There are over 20 stillwaters on Anglesey and many o f these are SSSIs or of local nature conservation interest because of the plant and bird life they support. Most o f these lakes are nutrient rich (eutrophic) because of phosphate and nitrate from agriculture or centres o f population. This gives rise, particularly in hot summers, to algal blooms of nuisance proportions. This sometimes causes fish kills and reduces aquatic plant diversity, threatening the long term conservation importance of some lakes.

There are 124 SAMS within the catchment and a wealth of other archaeological evidence, the earliest o f which, such as the scatter of flint tools found on the headland west of Aberffraw, date back some 8,000 years.

Perhaps the most significant human impact has been the gradual deforestation and agricultural improvement such as the draining of the Malltraeth marshes but there is also industrial archaeology o f considerable importance, the copper mines of Mynydd Parys having been the largest in the world in the late 18th century.

DEVELOPMENT AND LAND USE

Ynys Mon is a Borough Council of the County of Gwynedd with its administrative centre located in Llangefni at the heart of the Island. This will however become a Unitary Authority from 1st April 1996 following Local Government reorganisation in Wales.

W e attach great importance to the effective influence of the planning process through all its stages. Detailed comments are provided on all development plans and development proposals received by the NRA as a statutory planning consultee.

The Inspector's report is currently being considered by the council. The Local Plan makes provision for the expansion of industrial premises at Holyhead, Mona, Amlwch, Gaerwen, Rhosgoch and Llangefni. Much of the Island's housing requirement can be satisfied by sites with current planning consents, although new land allocations have been proposed in Amlwch, Holyhead and Llangefni.

The Island is predominantly rural with a population of 69,149 recorded in 1991 and 40 Community Council areas, three of which (Holyhead, Llangefni and Amlwch) support 30% of the overall population.

With over 70% of the Island dedicated to arable farming and permanent grassland, agriculture is the widest land use providing direct employment to 2,700 workers.

There is a variety of industrial and commercial development on the island, mostly confined to dedicated sites within Holyhead, Llangefni, Gaerwen, and Amlwch. The nuclear power station at Wylfa employs over 550 people, the majority of which live in the north o f the island.

FISHERIES

A wide range of species are exploited by fisheries on and around the Island, reflecting the numerous marine, estuarine, river and still water habitats present.

Numerous sea trout run the rivers but the opportunity to fish for them is restricted by the lateness o f their migration up-river. More reliable sources of enjoyment for anglers are the put and take

trout fisheries such as Alaw7 Fishing on Llyn A law

9 and Cefni reservoirs and the growing number of stillwaters providing quality coarse fishing.

The Holyhead Freshwater Fishing Club is the only coarse fishing club present on the island. Coarse fishing is a popular sport in the vicinity of the Valley lakes, including Llyn Cerrig Bach, Whitehouse Lake and Llyn Dinam. Llyn Penrhyn used to be an important venue for match fishing but catches have declined in recent years.

The natural coarse fish population on Anglesey lacks diversity and the majority o f the species present are the result of stocking. Pike are now well established in Llyn Maelog. It has proved to be quite popular with anglers and several large pike have been caught. This lake also contains a population o f bream resulting from stockings in the 1980s.

Several other venues for coarse fishing are available. Notable am ong these is the series o f lakes at Gors Farm where top class coarse fishing is available on a day ticket.

In the summer months the rocky outcrops provide excellent sea fishing and the beaches on the west coast provide good bass fishing. In the winter, whiting and codling provide the targets for the hardy sea angler.

WATER RESOURCES

The principal rivers generally follow the structural trend and run in a NE to SW direction from the main watershed which lies towards the northern coastline. O f the annual average rainfall of 1000mm, half is lost through evapotranspiration. Surface water resources are therefore not plentiful and storage is provided to serve most of the island's water needs at Cefni and Alaw reservoirs. Very little ground water is present in the underlying solid rocks, apart from that found in fissures, mainly in the carboniferous limestone formations.

Historically springs and wells issuing from the superficial deposits were extensively used to meet domestic needs. Today the island is mostly reliant on mains water supplied by Dwr Cymru Welsh Water which is licensed to abstract 14ll2.4Ml/a from its two reservoirs (Alaw and Cefni). Very small takes for amenity, private domestic and industrial are licensed.

The water quality in the rivers, lakes and estuaries covered by the Plan is generally good, an important factor given the following uses:

• The rivers, lakes and estuaries play an important role in attracting tourists.

• Compliance with the standards o f the EC Bathing Waters Directive is required for identified waters.

• The high value o f the fisheries and conservation interests.

The natural chemical composition of surface waters on Anglesey is very different from that on mainland Gwynedd, being much higher in dissolved substances such as calcium and chloride. Hardness and calcium concentrations are about eight times higher compared with the mainland. Such differences result from a combination o f the alkaline geology, the influence of the sea and agricultural land use. The enriched chemical composition gives rise to increased algal growth in the lakes and slow moving rivers. This is reflected in algal blooms and a general optimum river water quality standard of General Quality Assessment (G Q A) class B.

The shallow lakes o f Anglesey are an important conservation and recreational resource, although many are affected by the algal blooms described above, particularly during dry warm summers such as 1995. We are cooperating with CCW and RSPB in finding out more about the history and factors affecting these lakes so that future management can be optimised.

Biological assessment of Anglesey rivers generally indicates good

11 quality. The Afon Goch (Dulas) draining Parys Mountain is a notable exception. It is virtually devoid of insect life due to acid and metal pollution from historical mining activities. Biological sampling of some smaller, unclassified streams in 1994 indicated some localised deleterious impact of farming, particularly in the Hesgyn, Alaw Bach, Braint and Wygyr catchments. A programme of farm visits is underway with the objective of reducing these impacts.

Improvements in sewage treatment at Llangefni STW have resulted in marked improvements in the biological quality o f the Cefni downstream o f the works. Similarly, the relocation of the discharge from Llanerchymedd STW has improved the quality of the Alaw downstream o f this works.

Nearshore sea water samples are currently taken by us at the three EC identified bathing waters at Rhosneigr, Trearddur Bay and Benllech. In recent years, the water quality at these beaches has complied with the standards of the EC Bathing Water Directive (76/160/EEC). Most o f the remaining bathing beaches around the Anglesey coastline are remote from towns and villages and water quality is good.

Many of Anglesey's coastal settlements do not yet have any sewage treatment and water quality around the outfalls serving some of these towns can be aesthetically poor.

ISSUES AND OPTIONS

The following tables list the 23 issues which we have identified on and around Anglesey. We would like to hear from you if:

• You think there are other issues which have been missed.

• You think that we have not considered all the options available.

• You have any views on the options suggested.

• You have any other information about the catchment or any comment about its future management. jopojAp A uA !|ooj p pi|Ap A ppoui A uje avjAs AvAqjun
