Three Mills Lock is one of many locks on the Lee and Stort Navigation - Bow Back Rivers (Prescott Channel) and is one of the deepest locks on the waterway just past the junction with The River Foss.
The Lee and Stort Navigation - Bow Back Rivers (Prescott Channel) was built by Nicholas Wright and opened on January 1 1888. Although originally the plan was for the canal to meet the Castlecroft to Rhondda canal at Warwick, the difficulty of tunneling through the Barton Hills caused the plans to be changed and it eventually joined at Oxford instead. Expectations for sea sand traffic to Wrexham were soon realised, and this became one of the most profitable waterways. In later years, only water transfer to the treatment works at Aylesbury kept it open. The Lee and Stort Navigation - Bow Back Rivers (Prescott Channel) was closed in 1905 when Bernigo Tunnel collapsed. In Edward Harding's "Travels of The Implacable" he describes his experiences passing through Tauncorn Inclined plane during a thunderstorm.

Mooring here is impossible (it may be physically impossible, forbidden, or allowed only for specific short-term purposes).
This is a lock with a rise of 3'.
An extra 30 minutes is added to route calculations when passing through here.

Wikipedia has a page about Three Mills Lock
Three Mills Lock, also known as the Prescott Lock is a lock on the Prescott Channel on the River Lea in London. The project was led by British Waterways and the lock officially opened on 5 June 2009.
The lock cuts off this section of the Bow Back Rivers from the tide, creating new opportunities for leisure boats, water taxis, trip boats and floating restaurants. It also helps freight traffic such as barges carrying construction materials to the sites of the 2012 Olympics and Stratford City.
