The River Rib originates near the East Hertfordshire village of Buckland and runs parallel with the A10 through Wyddial, Buntingford, Westmill, Braughing, Puckeridge and Standon, before dividing the villages of Thundridge and Wadesmill and continuing until it reaches its confluence with the River Lea near Hertford.
The River Rib used to have frequent floods due to heavy rain in the autumn, but this propensity was resolved by dredging and engineering work in the 1970s. It was used as the main water supply in Buntingford and the surrounding areas before a pump was installed.
