From the River Thames to Hertford and Bishops Stortford

Bow Creek (the original tidal outlet of the Lee) joins the Navigation at Three Mills and joins the tidal Thames at Barking Road Bridge, after 1.3 miles (2.0 km) and Bow Locks. 

There is also a network of Bow Back Rivers, restored as part of the 2012 Olympics site, which connect to the Navigation above Three Mills. With the reopening of Carpenter’s Road Lock in 2017 the waterways are now navigable and passage can be booked through Canal & River Trust.

The Lee was an important waterway from Saxon times. About 1190, the Abbot of Waltham was permitted to make a cut to improve the navigation. In 1424 and 1430, it became subject to the very first Acts for the navigational improvement of any river. More improvements were made in the eighteenth century, which furthered the development of industry along the route. The Lee also provided an important supply of water to London.

History of the rivers

Richard Thomas has compiled a very informative website with very comprehensive information on the history of the Rivers Lee and Stort. 

In the early 1930s, significant investment was injected into the Bow Backs to improve their ability to accommodate both floodwaters and navigation. At this time two new locks were constructed at City Mills and Carpenters Road. In addition the Prescott Channel was constructed with a sluice gate at its southern end to retain water. In the 1950s the Prescott Channel sluice was removed when the mills ceased working and retained water was no longer required.  Commercial traffic ceased to use the Bow Backs after the Second World War, and they were largely left to silt up and deteriorate.

Olympic Park Waterways

In November 2003, consultation plans were published for the potential site for an Olympic park. These were firmed up following the announcement in 2005 that the Olympics games were to be hosted in London in 2012. The Olympic works included a new lock, subsequently named Three Mills Lock, on the Prescott Channel for the transportation of construction materials.

Prior to the Olympic development of the park, British Waterways had dredged the City Mill River.  With the subsequent restoration of City Mill and Carpenters Road Locks, and the the Bow Back Rivers, a second cruising loop was created.

Built in 1776, a tide mill museum on the Bow Back Rivers known as the House Mill, is the world’s largest surviving tidal mill and one of the best kept secrets in London
