Rains Brook is a tributary of the River Leam. Formed by a series of small headwater streams midway between Barby and Kilsby in Northamptonshire, it then flows west in a valley south of Rugby on the border between Northamptonshire and Warwickshire. It then runs south-west to where it joins the River Leam, between Kites Hardwick and Woolscott. See also List of rivers of England References Rivers of Northamptonshire Rivers of Warwickshire 2Rains
