The Padnal and Waterden Internal Drainage Board was originally constituted in 1827 and its District is situated north east of the City of Ely in Cambridgeshire, part of the South Level Fens.
This District has a highly complex system of land drainage/water level management/flood protection due to the physical environmental features that divide the District into five distinct and separate pumped catchments.
The District Boundary encloses an area of 1186ha. (2931ac.) which is entirely a pumped catchment.
The Prickwillow Padnal No. 1 District lies to the east of the Ely Ouse River and South of the River Lark and is boarded to the south by the Middle Fen and Mere Internal Drainage District. Part of the village of Prickwillow is within this catchment, which is intersected, east to west by the Ely to Norwich Railway Line.
The Littleport Padnal No. 2 District lies to the east of the Ely Ouse River, the north of the River Lark and is bordered in the east by the Burnt Fen Internal Drainage District.
The Kerridge District lies to the west of the Ely Ouse River and north of Leytons Catchwater. This District lies at the bottom of the south eastern slope of the Fen Island Town of Littleport. Surface water from the town of Littleport is intercepted by the Padnal Catchwater Drain (maintained by the Board) which discharges by gravity into the Ely Ouse. Catchwaters prevent intercepted surface water being pumped by the Board, or overwhelming of pumping plant causing flooding within the District.
The Redmoor District is situated to the west of the Ely Ouse River, south east of the Leytons Catchwater and north of the Fen Island Hamlet of Chettisham and City of Ely. Surface water from Chettisham and Ely is intercepted by the Kettlesworth Catchwater (maintained by the Board) which discharges by gravity into the Ely Ouse.
The Waterden District is situated to the west of the Ely Ouse River, south east of the Clayway Catchwater and encompasses the village of Queen Adelaide.
The old sugar beet factory lies on the southern boundary of the District at this point and surface water from part of the site is discharged to the Board’s pumped system through “Turbutsea”.
