The EAWA campaigns for the preservation, restoration and good management of all inland and tidal waterways in East Anglia.
The Norfolk and Suffolk Broads are a key area along with the main rivers - the Great Ouse, Nene, Welland and Witham.

But our work also covers lesser known waterways from the Chelmer in the south, the Blyth in the east to the Ancholme in the north plus the extensive Middle Level Navigations.

Denver "Complex"

Denver Sluice was first constructed in 1651 to exclude the tidal waters of the River Great Ouse from the South Level rivers.  It was destroyed in 1713 and rebuilt by Swiss engineer, Labelye in 1750. The present Sluice (with alterations made in 1923) dates from 1834 and was built by Sir John Rennie.  The main sluice incorporates one large vertical gate (now permanently sealed) and three smaller 'eyes' plus a navigation lock.  The Denver Complex now includes four additional sluices each serving a vital purpose in flood control or water management plus a Control building and Superintendent's accommodation.   
The A.G. Wright Sluice, first commissioned in 1964, allows water from the Ely Ouse to be diverted in times of high flow into the eleven mile long Relief Channel for discharge closer to Kings Lynn.  
A Diversion Sluice allows water from the Ely Ouse to be sent via the Cut-Off Channel, various Pumping Stations, an underground pipeline and a waterway network for storage in Essex reservoirs.  
The Impounding Sluice allows for flows in the Cut-Off Channel to be 'reversed' in connection with the Ely Ouse/Essex water transfer scheme.
A smaller Residual Flow Sluice maintains a small flow to refresh the Relief Channel and also monitors low flow rates.
The most recent addition to the Denver Complex was a new Navigation Lock, completed in 2002, which now allows boats to navigate the Relief Channel to Downham Market.  It is an aspiration that one day another lock will be incorporated into the Tail Sluice at the Kings Lynn end of the Relief Channel. This would enable craft to navigate safely to Kings Lynn and out into the Wash without using the Great Ouse Tidal River below Denver which has suffered so badly from silting in recent years.

Middle Level Navigations

The Middle Level Navigations lie in The Fens between the Rivers Nene and Great Ouse, and between the cities of Peterborough and Cambridge. Most of the area through which they run is at or below sea level, and attempts to protect it from inundation have been carried out since 1480. The Middle Level was given its name by the Dutch EngineerCornelius Vermuyden in 1642, who subsequently constructed several drainage channels to make the area suitable for agriculture. Water levels were always managed to allow navigation, and Commissioners were established in 1754 to maintain the waterways and collect tolls from commercial traffic.

Part of the Middle Level Navigations form a key link between the River Great Ouse and the River Nene and access to the canal system.  A secondary route via the Forty Foot River, Welches Dam Lock and the Old Bedford River is closed at present due to deterioration of the lock, water loss in the Forty Foot and neglect of the Old Bedford River, despite this being a statutory navigation which the Environment Agency have a duty to maintain under the Anglian Water Authority Act 1977. Both EAWA and the IWA are campaigning vigourously to ensure that this route is reinstated as soon as possible and not lost for the future.

River Welland between Stamford and Market Deeping

The Stamford Canal

In the Sixteenth century the people of Stamford submitted a petition to the crown asking permission to improve the navigation of the river Welland between Stamford and Market Deeping by creating a new cut to bypass the watermills. A 'Navigation Act' was signed by Queen Elizabeth 1 in 1571.

The Fens Waterways Link (including South Forty Foot River)

Following promotion of the restoration of this waterway by East Anglian Waterways Association, Fens Tourism (a consortium of local authorities) undertook a feasibility study of the route. This report was encouraging and EA adopted the project as ‘The Fens Waterways Link’, which it launched in 2004 with support from local authorities, EAWA and IWA..

THE RESTORATION OF THE GREAT OUSE.

Compiled by Alan Faulkner

By the beginning of the 1900s the River Great Ouse was effectively closed to navigation from St. Ives upstream from St. Ives up to Bedford as the locks were inoperable. Various attempts were made to re-open some of the locks for pleasure traffic, notably at the Bedford end, but these were short-lived.
