In its role as 'Guardian of the Water Environment', the NRA is committed to preparing a sound plan for the future management of the region's river catchments. This Consultation Report is the first stage in the catchment management planning process for the upper reaches of the River Severn. It provides a framework for consultation and also a means of seeking commitment from those involved to realise the full environmental potential of the Catchment. We look forward to receiving comments and contributions from interested organisations and individuals. These will enable a Final Plan to be produced, balancing the conflicting demands placed upon the natural water environment. Dr J H Kalicki Area Manager Upper Severn Area THE NRA's VISION FOR THE CATCHMENT The catchment of the upper reaches of the River Severn is predominantly rural in character, and is an area known for its attractive upland landscape and great natural beauty. The rivers in the catchment support high class fisheries and provide a diversity of habitats for a wide range of flora and fauna. The catchment is home to around 75,000 people, who depend on the water environment in many ways and value it for the amenities and enjoyment it provides for their local communities. The picturesque and unspoilt countryside within the catchment is also increasingly seen as a tourist attraction. The catchment has an important role far beyond its physical boundaries, and indirectly affects many people who live outside the catchment. One reason is the plentiful high quality water in its rivers and lakes, which is used as a major source of water supply to surrounding areas. Also of note is the fact that the catchment comprises the upper parts of the longest river in Britain. What occurs in these sensitive upper reaches can have an impact downstream for up to a distance of some 350 kilometres. The NRA's vision for the catchment is to: * safeguard existing high quality water and habitats, and where appropriate work towards enhancing the water environment. * work in an integrated manner towards resolving those issues and problems that have been identified in the plan. * ensure that future demands on the water environment from both within and outside the catchment are planned and managed in a balanced and sustainable way for the benefit of all users. Key objectives of this plan are to: * maintain the highest possible level of protection for the water environment, restore damaged habitats and protect rare and threatened species. * address the problem of stream acidification. * improve water quality of the 41 km of rivers where the required longer-term River Ecosystem water quality objective is not already achieved. * improve fisheries by making spawning areas in rivers more accessible to migratory fish. * ensure proper management of the catchment's valuable water resources. * influence the planning processes of local authorities to ensure that development does not adversely impact on, and wherever possible proceeds in a way to benefit, the water environment. The realisation of the NRA’s vision will be achieved through a balanced management approach to all activities in collaboration with all users of the catchment. It is our intention to work in partnership with all relevant agencies and representative organisations to promote and achieve an integrated approach to managing the catchment. The plan will ensure required improvements can be carried out, and future demands catered for, in a sustainable manner.

Many different uses interact, or compete for water or water space, and will inevitably come into conflict with one another. The NRA is the major manager of the water environment in England and Wales and aims to reconcile conflicts between water users as well as its general duties that include:- * Control of pollution and improving the quality of rivers, canals, groundwaters and coastal waters. * Flood defence, including the protection of people and property. * Flood forecasting and flood warning. * Effective management of water resources. * Maintenance, development and improvement of fisheries. * Promoting the conservation of the natural water environment. * Promotion of water-based recreation. * Navigation (in some areas). Catchment Management Plans (CMPs) allow the NRA to balance the competing requirements and interests of all users. The process allows the environmental potential of a catchment to be realised in terms of water quality, water quantity and physical features. In the future, CMPs will provide the the framework within which the NRA can implement the new system of Water Quality Objectives (WQOs).
