 Garston Lock was built between 1718 and 1723 under the supervision of the engineer John Hore of Newbury, and this stretch of the river is now administered by Canal & River Trust and known as the Kennet Navigation.It has a rise/fall of 7 ft 7ins (2.29m).One of only two remaining working examples of turf sided locks on the canal (the other being Monkey Marsh Lock), Garston Lock has been described as needing "more water to operate than the now more common brick or stone-sided variety" as the sloping sides increase the volume of the lock.
