Dowdeswell Reservoir and former water treatment works lie below the parish of Dowdeswell in Gloucestershire. They were originally built by Cheltenham Corporation to supply the town of Cheltenham with drinking water (since 1886) and subsequently became part of the Severn Trent network.
It is currently owned and managed by the Environment Agency and is managed as a 'balancing pond' for the water catchment from the east end of the valley. [1]
Severn Trent closed the water treatment works with the commissioning of the Mythe Treatment Works on the river Severn, and the reservoir itself became a flood storage reservoir for the River Chelt in an attempt to protect the town of Cheltenham from flooding from the east. The town nonetheless suffered flooding in the July 2007 floods though this was not only from the river Chelt at Dowdeswell, but from all the streams which join the Chelt within the town and its outskirts. The Dowdeswell 'balancing pond' only deals with the Chelt (really a stream at this point in its life), Dowdeswell stream and runoff from the limestone scarp.
The Cotswold Way National Trail runs alongside the dam end of the reservoir (below the dam embankment) and alongside the western edge of Dowdeswell Woods.
The reservoir and wood are listed in the ‘Cotswold District’ Local Plan 2001-2011 (on line) as Key Wildlife Sites. [2]
They are near Arle Grove nature reserve.
There is a site management plan from 1975 for the Dowdeswell Reservoir Nature Reserve. [3] There are site management plans for the Dowdeswell Wood Nature Reserve for 1993 to 2002 and 2002 to 2011 along with various annual reports. [4]

These areas (Reservoir, Residuum, Scobb's Grove) (grid reference SO997198 ) were established as a 9.3-hectare (23-acre) nature reserve with the Gloucestershire Trust for Nature Conservation (now the Gloucestershire Wildlife Trust) in 1973 under agreement with the North-West Gloucestershire Water Board originally.
The main body of water supports many resident and wintering wildfowl: Moorhen, Coot, Mallard and Little Grebe and Great Crested Grebes regularly breed. The surrounding habits provide nesting sites. There is a significant aquatic and grassland flora including grassland supporting Common Spotted Orchid, Pyramidal Orchid and Cowslip. The reservoir is a major spawning ground for the Common Toad and there are signs which are opened each year at migration time on the A40 which runs alongside the reservoir. There were originally two toads tunnels from the south side of the A40 into the reservoir grassland, but these have since been removed as a result of roadworks.
The reservoir supports the native crayfish (Austropotamobius pallipes) which is protected on Schedule 5 of the Wildlife & Countryside Act 1981. During the engineering works undertaken in 1998 Severn Trent put in place a management programme for the protection of this white-clawed crayfish. [6]
The associated water treatment yards historically have supported a significant flowering area of Autumn Lady's Tresses.
Scobb’s Grove is a separate copse of damp Ash, Alder, Hazel and Willow woodland containing ferns, Small Teasel and Alternate-leaved Golden-saxifrage. It has an interesting bird life including Owls.
There is currently no lease agreement for these areas with the Gloucestershire Wildlife Trust.

Dowdeswell wood (grid reference SO993204 ) is a 82-hectare (200-acre) site and lies on the northern slopes of the Chelt valley and one mile east of Charlton Kings. The wood forms part of the gathering grounds for Dowdeswell Reservoir and became an extension to this reserve in 1992 under agreement with Severn Trent.
Extensive management work was carried out and a way-marked series of paths were created accessible from the Cotswold Way national trail.
The character of this wood was changed dramatically in the 1950s and subsequently by replacing with conifers following felling of mature Oak, Ash, Beech and many diseased Elms. Replanting work has replaced conifers for broad-leaf.
A good ground flora is present mostly in the broad-leaved areas. Bluebell, Yellow Archangel, Wood Anemone, Moschatel, Early-purple Orchid and Ramsons (wood garlic). There are Roman Snails in a site of a Roman Settlement in the north of the wood. The Common Dormouse is present as are Roe and Muntjac deer.
There is currently no lease agreement for these areas with the Gloucestershire Wildlife Trust.

The Gloucestershire Wildlife Trust is the Gloucestershire local partner in a conservation network of 46 Wildlife Trusts. The Wildlife Trusts are local charities with the specific aim of protecting the United Kingdom's natural heritage. The Gloucestershire Wildlife Trust is managed by a board of trustees elected from its membership who provide overall direction for the development of the trust and there are advisory committees. The work of the trust is carried out through staff and volunteers.
The Cotswold Water Park is the United Kingdom's largest marl lake system, straddling the Wiltshire–Gloucestershire border, north-west of Cricklade and south of Cirencester. There are 180 lakes, spread over 42 square miles (110 km2).
Coombe Hill Canal lies in the Vale of Gloucester, south west England, north of Leigh and runs west 2.75 miles (4.43 km) from Coombe Hill Basin to the River Severn near Wainlode Hill. It opened in 1796 and closed 80 years later in 1876, after the only lock was damaged by flooding. The Gloucestershire Wildlife Trust purchased the Coombe Hill Canal nature reserve in 1985 and the area is managed by the trust. Adjacent to the Coombe Hill Canal is a large area of wet meadowland situated midway between Gloucester and Tewkesbury to the west of the A38, which was purchased by the trust in 1999. There is a north and a south meadow. This land and the Canal itself often flood in winter, which attracts hundreds of wildfowl.
