History of the Witham Navigable Drains
The River Witham has a transport history dating from Roman times and was improved for commerce from the 18th Century. It becomes tidal at Boston leading to The Wash. Upstream it heads towards the Fossdyke Navigation and the rest of the inland waterway system via Torksey. The Kyme Eau/Sleaford Navigation connects with the River Witham at Chapel Hill.
From Anton's Gowt Lock the River Witham gives access to the Witham Navigable Drains, an area bounded to the east by The Wash and which extends into an intricate system of waters which, though navigable, are primarily for the drainage of large areas of Fenland. Some of the Drains are modified streams whilst others are entirely man-made. Several have names only known to locals.
The Drains were once extensively used for the carriage of agricultural produce and coal but many of their locks and navigational artefacts have fallen into disrepair. They are now more usually frequented by fishing vessels and pleasure craft though the heights of the embankments or the level of the water below the surrounding landscape may curtail views around the essentially flat landscape. A preserved windmill can be seen at Boston and St Botolph's Church, locally known as Boston Stump, is claimed to be the largest parish church in England.
Navigators should be aware that water levels are prone to fluctuation especially at times when the Drains are being called upon to exercise their primary function. Navigation is given low priority and there are minimal facilities. During winter months levels may be altered without warning. Other hazards include shallow water and low bridges.
It is advised that the Witham Fourth Internal Drainage Board be contacted prior to attempting access into the network. Telephone 01205 310099
