Bristol BS32 4UD THE NRA'S VISION FOR THE RIVER ANCHOLME CATCHMENT The NRA was established in 1989 and has the role of “Guardian of the Water Environment”, it aims to balance the legitimate interests of all those who use the water environment and to ensure that future development is sustainable. Sustainable development is seen as “development which meets the needs of the present without compromising the ability of future generations to meet their own needs”(Bruntland Report 1987). The Catchment is home to approximately 49,000 people and the NRA’s vision for it is to create a river and wetland environment that these people will want to use, live and work within. This will involve the protection of high quality habitats and where appropriate work towards enhancing the water environment. Over the last few centuries mans activities have fundamentally influenced and altered the landscape to create productive arable farmland. The fenland/meadow land that would have dominated the 13th century landscape has all but disappeared. The NRA’s challenge in this catchment is not to turn the clock back. It is to re-dress the balance and improve the conservation value of the Catchment, whilst achieving the sustainable management and protection of the quality and quantity of surface and ground waters, the provision of effective flood defences and the development of recreational potential. Within the 5 year life of this plan the NRA and partners aim to achieve the following key actions which will represent a significant step towards the sustainable management of the Ancholme Catchment. • to integrate the needs of flood defence and conservation to increase the standard of flood protection whilst improving the diversity of riverine habitat and associate plant and animal species. • to maintain and improve water quality. • to refurbish South Ferriby Lock to maintain navigation passage with the Humber. • to continue to operate and effectively manage the Trent Witham Ancholme Water Transfer Scheme. • to maintain and improve fish populations. • to coordinate the recreational demands on the catchment. MAP OF THE CATCHMENT Front Cover: South Ferriby Lock RIVER ANCHOLME CATCHMENT MANAGEMENT PLAN FOREWORD The National Rivers Authority, NRA, was created in 1989 as an independent environmental watchdog. It has as its prime purpose the protection and improvement of the aquatic environment throughout England and Wales. In achieving this purpose the NRA seeks to effectively manage water resources, substantially reduce pollution and provide effective flood defence for people and property. It aims to operate openly and balance the interests of all who benefit from and use rivers, groundwaters, estuaries and coastal waters. The NRA has chosen to develop the concept of Catchment Management Planning to help it achieve its aims. A Catchment Management Plan (CMP) treats a river, together with the land, tributaries and underground water connected with it, as a discrete unit or catchment. The approach considers all major uses which impact upon the water environment in a catchment. It seeks to identify and resolve problems within the catchment in an integrated way, developing a partnership approach, where appropriate, towards dealing with those problems. This document marks the start of that process by inviting the public and all organisations with an interest in the water environment to comment on its contents, to identify their concerns for the River Ancholme Catchment and to suggest any options for their solutions. The River Ancholme Catchment includes some of the most productive and intensively farmed arable land in England. The conversion and use of land for agricultural purposes in the Ancholme valley over the centuries has significantly transformed what would have been a wetland environment, subject to regular inundation and a haven for wildlife, into one of substantial agricultural and economic value protected from inundation by fluvial and tidal defences. Large tracks of the Ancholme valley lie at or below high tide levels. On the slopes of the valley there are extensive woodlands at South Willingham and at Broughton, only remnants of which survive on the valley floor. In the Winterton Beck sub­ catchment extensive mining operations have changed the character of that valley to the extent that the route of the Winterton Beck has been significantly altered. Water resources in the catchment are supplemented by a pipeline transfer providing water from the River Trent via the River Witham into the River Ancholme at Newton by Toft.
