Waltham Common Lock (No 10) is a lock on the River Lee Navigation at Waltham Cross in Hertfordshire, England. The lock is located in the River Lee Country Park and stands close to the Broxbourne White Water Canoe Centre.[1] At the tail of the lock is the Powdermill Cut dug in 1806 to connect the Waltham Abbey Royal Gunpowder Mills directly to the then-new navigation.[2]
