Idle Catchment Partnership Action Plan Working together for a better water environment Our Vision for the Catchment Our Shared Vision for The Idle Catchment To conserve and enhance the Rivers Idle, Ryton, Poulter, Meden, Maun, their tributaries and surrounding land, to create a healthy and wildlife- rich water environment for the benefit of both people and biodiversity. Foreword ‘Fed by the Rivers Ryton, Poulter, Meden, Maun and Rainworth Water, the River Idle flows in the shape of an inverted question mark north through Retford, under the Chesterfield Canal, nudging the old port of Bawtry, negotiating the hill at Gringley and encircling Everton, Gringley and Misterton Carrs before discharging into the Trent at West Stockwith. With the entire catchment covering 340 square miles and a population of over 250,000 dependent on the water courses, it is clear that there are considerable pressures on the water resource. The reputation of the River Idle is bound up in its name – it is Idle both by name and nature, flowing gently over its last five mile section so flat there is a fall of less than 1:1,000. Prior to reaching its heavily engineered pumped outfall the river and its tributaries navigate a path from and through many urban areas, historic ducal houses and important wetland areas, as well as the last remaining area of the ancient Sherwood Forest, providing a natural boundary to several traditional village settlements and draining swathes of productive agricultural land. It is important to protect and enhance the health of the rivers, including their surrounding habitats, biodiversity, water quality, productive capacity and the welfare of those who live within its embrace. Predictable and moody as the rivers are, people are not always inclined to treat them with respect – intensive land management and pollution have taken their toll on the catchment’s well being, although the decline in ecological status and water quality in relatively recent times is being addressed and in some ways effectively reversed. The Idle Catchment Action Plan has been established to achieve this, and to raise the awareness of the rivers and their environment amongst those who live and work in the catchment and whose lives are affected by their closeness to them. It is designed to make the most of the role of the local communities to deliver environmental, agricultural and social improvements through collaboration, education and ground work. There is much more to do, so please read on.....’ Tim Farr, Chair of the Regional Flood and Coastal Commitee River Idle Sub-Catchment Action Plan 2 Background Image: P David Background to the Idle Catchment The Idle and Torne catchment covers a wide geographic area, spanning multiple districts, 4 Counties and 2 regions. Due to the range of complex issues and competing priorities in the area, it seemed appropriate to split the catchment into two sub-catchments based on the two rivers. A separate steering group has been set up for the Torne, hosted by Yorkshire Wildlife Trust. The sub-catchment includes the following rivers and their tributaries; Meden, Maun, Poulter, Rainworth Water, Vicar Water, Ryton and of course the River Idle itself. These drain over 879km2 (1) of the surrounding land. Much of this area is rural, although it does cover some major urban areas including Mansfield (pop c.100,000), Worksop (pop. c.40,000), Sutton in Ashfield (pop. c.42,000) and Retford (pop. c.21,000). The large area and the mix of urban and rural land uses create a diverse range of pressures on the water catchment, including: • Urban point source pollution from areas of industry and housing, misconnections etc • Phosphate and nitrate inputs from waste water treatment works Image: Sean Browne • Rural point source and diffuse pollution • Heavily modified channels • Low flows in some watercourses • Flooding risk from many watercourses • Over-abstracted aquifers • Groundwater pollution • Widespread loss of riparian marginal habitats • Degraded riverine fauna • Presence of invasive non-native species Point Source/Diffuse Pollution Point source pollution is where the contaminants are coming from a single point – such as a waste treatment works (WTW), or from a factory. Diffuse pollution is from a much wider source, such as an area of farmland or from a housing estate. 3 What is the Catchment Based Approach? Image: Thornypup A shift in thinking led the UK government to realise that looking at smaller water catchment areas rather than large river basins was a positive step in achieving improvements to water bodies and their associated environment, and towards achieving the targets of the Water Framework Directive (WFD). This led to the introduction of the ‘catchment based approach’ by DEFRA (Department for Environment Farming and Rural Affairs) to enable local stakeholder groups to promote the protection and improvement of the water environment. On World Water Day (22 March 2011), Richard Benyon, Minister for Natural Environment and Fisheries, announced that to bring about genuine improvements to the water environment we should: ‘Provide a clear understanding of the issues in the catchment, involve local communities in decision- making by sharing evidence, listening to their ideas, working out priorities for action and seeking to deliver integrated actions that address local issues in a cost effective way and protect local resources.’( 2) The objectives for the Catchment Based Approach are(3): 1. To deliver positive and sustained outcomes for the water environment by promoting a better understanding of the environment at a local level; and 2. To encourage local collaboration and more transparent decision-making when planning and delivering activities in order to improve the water environment. What is the Water Framework Directive? The Water Framework Directive (WFD) is a piece of EU legislation which was adopted in 2000. Its main purpose is to protect inland, coastal and groundwater’s and to ensure that all waterways reach either good ecological status, or where this is not possible, good ecological potential, by 2027. The status of the water is assessed using the following criteria • Biological quality (fish, invertebrates and aquatic flora) • Hydromorphological structure (river bank and bed structure, continuity) • Physio-chemical quality (dissolved oxygen, temperature, nutrients) • Chemical quality (phosphates and other pollutant levels) If a water body is found to fail on just one aspect of this, then it will fail to meet the required standards. A large part of the Catchment Based Approach is the promotion of ownership of the water on a local level, with communities and landowners being involved in decision making and project leadership. River Idle Sub-Catchment Action Plan 4 What are the problems facing the Sub-Catchment? Under the WFD, problems that are identified as causing the failures as described are called “Reasons for River Trent Failure”. The principal Reasons for Failure (RFF) A631 currently facing the Idle sub-catchment are M18 as follows: A1(M) River Idle Oldcotes Dyke 1. Pollution from waste water, particularly discharges from sewage treatment works and mines. A57 River Ryton Chesterfield Worksop Retford 2. Pollution from rural areas, Canal A1 predominantly, mixed agricultural run- M1 off. Millwood Brook 3. Physical modification of the river, mainly A616 Great Lake River Poulter historically for land drainage. A614 In addition, the catchment has serious River Meden Ollerton problems to resolve with regard to Sookholme Brook groundwater over-abstraction and pollution, River Maun urban run-off, barriers to eel, coarse fish and salmonid passage, and tensions around Vicar Water flood defences and the protection of Mansfield Rainworth Water N farmland. Cauldwell Brook A617 Main Roads Rivers Kirkby in Ashfield Canals Urban Area Catchment Boundary Phosphates Phosphates are a group of inorganic compounds which contain phosphorus. They are found within fertilisers and detergents and contribute greatly to pollution levels in water. They quickly contribute to increased nutrient levels, which in turn cause algal blooms in rivers and lakes which drastically reduces the amount of dissolved water, and therefore prevents other aquatic life from surviving. 5 The Action Plan Image: Rob Pettifer The aim of this document is to look at 5 different areas, which were identified through stakeholder engagement, where we would like to make a positive difference to the water environment. 1. Farming 2. Nature 3. Community 4. Industrial and Urban 5. Water Management This plan should be read in conjunction with the catchment priorities map which details priorities identified during two stakeholder workshops held in December 2013, and from follow up consultation. The map is a working document which will be updated as and when new projects are identified and current projects are Image: Jeff Smith River Idle Sub-Catchment Action Plan 6 Farming In recent years, many farmers have made Livestock Drinking Bays serious efforts to reduce pollution into The aim of a livestock drinking bay is to allow livestock to watercourses from their farms, not least drink from a watercourse, while preventing them from because it makes good business sense not to standing in the water.
