Marlow Lock

Marlow Lock is a lock and weir situated on the River Thames in the town of Marlow, Buckinghamshire, England, about 300m downstream of Marlow Bridge. The first pound lock was built by the Thames Navigation Commission in 1773.

A weir at Marlow is recorded in Domesday book, and there are 14th century records of a winch to pull traffic through a flash lock. The lock was very problematical and in the 16th and 17th century there are accounts of conflicts between millers and navigators. A particular problems was the shallow draught. The first pound lock was built of fir in 1773, the seventh downstream of the eight built after the 1770 navigation act. It was upstream of the present lock on still proved problematical. Rollers were needed to guide barges in, and as there was no towpath, barges needed tow ropes several hundred feet long. The lock needed extensive repairs in 1780 and a year later eel bucks had to be removed from the flash lock in case it was needed. The first lock house was erected in 1815 and in 1825 the lock was reconstructed on its present site of Headington stone. The weir was rebuilt in 1872. The last rebuilding of the lock occurred in 1927.
