River Witham Source – Where the Journey Begins
The River Witham rises near the village of South Witham, south of Grantham, within the Lincolnshire Limestone region. Its springs emerge from gentle farmland and rolling hills, providing the river with clear waters that begin an 82-mile journey across the county. This area is celebrated for its natural beauty and the agricultural lands surrounding the source.
From the very beginning, the River Witham has supported local communities. Its waters have been historically used for irrigation, land drainage, and early transportation. The source marks not only the start of a physical journey but also a key point in Lincolnshire’s ecological and cultural history, influencing settlements and farmland practices.
Route of the River Witham – Cities and Towns Along the Way
The River Witham passes through several towns and cities, including Grantham, Lincoln, and Boston, connecting rural landscapes with urban centres. Along its route, it travels beneath historic bridges, winds through gentle countryside, and eventually becomes tidal near Boston. These towns owe much of their development to the river, which provided water, trade routes, and fertile land.
Additionally, the river links with navigation channels such as the Fossdyke Navigation, highlighting its historic role in transport and commerce. The route of the River Witham demonstrates a blend of natural beauty and human development, with walking and cycling paths offering residents and tourists a unique way to explore Lincolnshire.
History and Cultural Significance

The River Witham has a long and rich history dating back to Roman times when it served as a navigable route for trade and communication. Over the centuries, it supported agricultural growth and industrial activity, shaping the economy and culture of Lincolnshire. Lincoln and Boston, located along its banks, developed into important towns thanks to the river.
Cultural landmarks along the river, such as historic mills, bridges, and ports, reflect its enduring influence. The tidal section near Boston, known as The Haven, enabled centuries of maritime trade, reinforcing the river’s significance.
