The river is fed by a number of sources including springs from Biggin Moor, Great Hormead Brook, Little Hormead Brook and various field ditches, including the Braughing Bourne - the site of a former glacier from the Ice Age.
It flows south, close to the B1368 road to the southwest of Braughing where it joins the River Rib at Gatesbury.
[1] Until recently the river was diverted at this point to irrigate watercress beds before flowing into the Rib.
The river is prone to severe flooding after heavy rain, rendering the fords impassable, particularly in the autumn and winter months.
In 1922, a donkey and cart were swept away when its owner tried in vain to cross Sheeps Lane Ford.
