Rainford Brook is a small river that flows through the county of Cheshire in England. It is a tributary of the River Weaver and is approximately 10 miles long. The brook rises in the village of Rainford and flows through the towns of St Helens and Widnes before joining the River Weaver near the town of Runcorn.
The brook is home to a variety of wildlife, including brown trout, grayling, and eels. It is also an important habitat for birds such as kingfishers, herons, and mallards. The surrounding area is predominantly agricultural, with fields and meadows lining the banks of the brook. There are also several small woodlands and nature reserves in the area, providing additional habitats for wildlife.
Despite its relatively small size, Rainford Brook has played an important role in the history of the area. It was once used to power several water mills, which were used for grinding corn and other crops. Today, the brook is a popular spot for fishing, walking, and birdwatching, and is enjoyed by locals and visitors alike.
