Swallow Beck is a small stream that runs through the county of Lincolnshire in England. It is a tributary of the River Witham and is approximately 10 miles long. The stream starts near the village of Waddingham and flows through the towns of Kirton in Lindsey and Brigg before joining the River Witham near the village of South Ferriby.
The Swallow Beck catchment area covers approximately 60 square miles and is predominantly agricultural land. The stream is home to a variety of fish species, including brown trout, grayling, and chub. The surrounding area is also home to a variety of wildlife, including otters, water voles, and kingfishers.
Despite its small size, Swallow Beck has played an important role in the history of the area. The stream was used to power mills in the past, and evidence of these can still be seen along its banks. Today, the stream is a popular spot for fishing and walking, with several footpaths running alongside it. The Swallow Beck also plays an important role in flood prevention, with several flood alleviation schemes in place to protect nearby towns and villages.
