The weir stretches a long way upstream above the lock.
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.
Access to the lockEdit
The lock is easily accessible, being located in the town. Lock access from the Thames Path requires a short walk through town back streets.
Reach above the lockEdit
The long weir stretches several hundred yards above the lock, and beyond it is Marlow suspension bridge close to the church. Once the river leaves the Marlow, it curls through hills and beechwoods. On the Berkshire side is Bisham Abbey, a fine old mansion associated with Anne of Cleves and Queen Elizabeth that is now one of the National Sports Centres. Further upstream is the church of Bisham itself.
Temple Mill Island is just downstream of Temple Lock.
Temple Regatta takes place in early May between Marlow Bridge and Temple Lock, and Marlow Town Regatta is held in June.
