Introduction
A little way south of the Old Bedford Sluice at the northern end of the Counterdrain/Old Bedford River (CD/OBR) at Salters Lode, there is a cutting though part of the western bank of the river that some boaters refer to as a boat turning place but in fact leads to a flood relief spillway known as the Well Creek Weir.The name seems to me to be rather inappropriate as its suggests there is a weir on the Well Creek itself, which there isn't. But this is the fens, where names so often cause confusion to strangers.

The spillway and reasons for it
The CD/OBR drains waters from Colne and Somersham in the south and the fen areas west of the washes, all part of the Middle Level. Water should be discharged by gravity via the Old Bedford Sluice/Lock into the Great Ouse Tidal River, thence to sea .... but ....If the sluice is tide locked or cannot be operated for other reasons (e.g. siltation) and the CD/OBR level reaches 1.15m AOD at Welches Dam (WD), Welney Sluice Gate closes and the WD pumping station starts up (both automatically) transferring water from the CD/OBR into the River Delph.
If the level of the CD/OBR at Salters Lode still rises and reaches 1.65m AOD despite the above operations, water flows over the 3m wide weir into Well Creek, part of the Middle Level system, and eventually to sea via the MLC pumping station at St.Germans.
In 1996 the NRA refered to this simply as Well Creek Weir. In 2002, an EA report called it Well Creek Weir & Sluice.

The groves in the concrete enable dam-boards to be fitted to block the weir.
The cut through the bank has been used to turn boats around.
