The City Mill River is a watercourse that is a tributary of the River Lea and is part of the Bow Back River in London , England. It originally supplied the City Mill - a chemical factory - with water in the late 19th and early 20th centuries. In the 1930s the factory closed and the river was closed with a sluice gate at each end. The City Mill Lock at its southern end was renovated and reopened in 2010.

history

The City Mill River branches off from the River Lea and ran past the City Mill. City maps from 1895 and 1923 show them as a chemical factory. The factory was on the river and a junction to the west of the current course flowed into the Waterworks River downstream of the factory. The outflow from the factory went into a large basin that was also part of the Waterworks River. By the late 1920s, the Bow Back Rivers, including the City Mill River, were in very poor condition. The Lee Conservancy Board, together with the West Ham Corporation, received government funding to improve the situation as part of an unemployment project. The work was approved by the River Lee (Flood Relief) Act of 1930 and remodeling began in 1931; it lasted four years.

The course of the river was hardly changed except at the southern end, where the factory was demolished and the course was led through the former factory site. The factory basin was partially filled and the course of the river was connected directly to the Bow Back River. This course of the river was moved a little further north. The Waterworks River was widened and a connecting lock was built between the two waterways. The river was no longer affected by the tides , as City Mills Lock locked it to the south and Carpenter's Lock to the north. The water level was kept in line with that of the Limehouse Cut. This means that only extremely high tides can still reach the watercourse, as the Limehouse Cut is controlled by the Bow Locks, which can be flooded at times.

The City Mill Lock

The City Mill Lock with the double lock gate that can open in both directions.

The City Mill Lock, which connects the Bow Back River and the southern end of the City Mill River to the Waterworks River, was built as part of improvements in the 1930s. Unlike Carpenter's Lock, which is equipped with vertical swing gates, the City Mill Lock is equipped with standard ship lock gates. Two pairs of lock gates to the west allow the lock to be used when the water level in the Waterworks River is lower than the City Mill River and a third pair prevents high tides in the Waterworks River from opening the gates of the City Mill River. The lock is 6.1 m wide and can accommodate ships up to 27 m in length. The original lock gates had been in use for almost 70 years, but in 2000 they were deemed too unsafe and replaced with barriers.

In 2005 the lock was renovated as part of an environmental improvement program for a new building project nearby. Three pairs of steel gates costing £ 200,000 were installed. Another £ 100,000 was spent on work such as access to the lock. As a result, the lock was put in good condition, but it was still inoperable because neither manual opening devices nor machine operation were installed. Funding for these devices came from funds related to the 2012 Summer Olympics . Another £ 200,000 was spent on equipping the lock to make it safe for boats to use. The work was completed in 2010 and the lock officially opened on July 31, 2010.

The work also included combating plants that hinder ship operations, especially buttercups, similar to buttercups .
