River Mease


The River Mease is a lowland clay river in the Midlands area of England. It flows through the counties of Leicestershire, Derbyshire and Staffordshire and forms the administrative border between these counties for parts of its length.
The river and the lower part of one of its tributaries, the Gilwiskaw Brook are both protected as "one of the best examples of an unspoilt meandering lowland river". The river receives protection under European Union law as a Special Area of Conservation ; and protection under UK law as a Site of Special Scientific Interest.

Description

The Mease is formed by a confluence of smaller streams near to the village of Norton Juxta Twycross in North West Leicestershire. It flows westwards for approximately 16 miles across a largely rural and agricultural landscape to its confluence with the River Trent at Croxall in Staffordshire, with its waters eventually reaching the North Sea via the Trent and the Humber Estuary.
The river flows through areas underlain with bands of Triassic Period sandstone and Mercia Mudstone. After flowing through a wide valley between the villages of Measham and Appleby Magna, the land opens up into flat countryside: the river's path is not of steep topography, meaning the river flows gently and meanders "passively".
The path of the river has changed little over time. Historical alterations were made near to the villages of Clifton Campville, Harlaston and Croxall, with the addition of weirs and leats to serve mills.
In the 1980s work was undertaken to deepen the Mease between the village of Measham and its confluence with the River Trent: this was part of a "comprehensive arterial drainage scheme" which was designed to allow land drains to drain into the river.

The village of Measham takes its name from the River: Measham means: the homestead on the River Mease.

Wildlife

The river is a designated site of special scientific interest due to the fish that it supports. Of particular interest are the resident populations of spined loach and European bullhead , white-clawed crayfish and European otters.
The most numerous fish in the river are chub and roach; with dace, pike, perch and gudgeon also recorded.
The river's wildlife is highly sensitive to pollution and fish numbers have fallen since 2007.
Natural England's report in February 2010 reported that the river's two special fish were both being adversely affected by pollution: both in terms of having lower than expected population sizes, and the river failing to provide favourable conditions for them to live.
Other wildlife, such as the white-clawed crayfish, have been pushed along the river to its confluence with the River Trent. White-clawed crayfish numbers have also been negatively affected by infiltrating foreign American signal crayfish, which have entered the river from a pool at Catton Hall.

Pollution

The river receives the outflow of 9 Sewerage Treatment plants, as well as the outflow from 10 private sewerage operations.
In addition the river receives the outflow from several opencast coal mines.
The river has suffered reduced fish numbers since 2007 when the Environment Agency stopped artificially restocking the river. The Environment Agency are instead trying to encourage a natural recovery following several "pollution incidents".
The main pollutant is thought to be phosphates and the main cause of the pollution is thought to be the Sewage Treatment Plant at Packington, which is operating at full capacity, leading to "overflow" being released into the river via the Gilwiskaw Brook. The water quality of the majority of the river is recorded as "moderate"; the section between Harlaston Bridge and the confluence of the River Trent is recorded as "poor".
Following pressure from the Environment Agency, North West Leicestershire District Council refused to grant planning permission for any construction work which would add to the sewage outflow: this included housing developments, hotels and business parks.
In November 2012, following fears that the situation was damaging the local economy, North West Leicestershire District Council announced a new plan. The council's plan would not stop the pollution of the river, nor prevent the additional outflow and pollution from new developments; instead developers would have to make a one off "significant contribution" of between £225 and £250 per new house built. South Derbyshire District Council and Lichfield Borough Council have both made similar proposals, with South Derbyshire planning a one off charge between £86 and £354 per new house. The money from these schemes would then be used on projects designed to improve the river's water quality.
These schemes have been heavily criticised as they do not prevent or reduce sewage outflow into the river, and, with resumed building, outflow and pollution will increase. A proposed development of houses on Leicester Road, Ashby-de-la-Zouch, is predicted to increase sewage outflow by 110 cubic metres a day; with an added 37 cubic metres a day of surface water runoff also added to the river. This has added to fears about worsening flooding as large areas of the Gilwiskaw Brook and the River Mease regularly flood after heavy rain.
