A lock keeper, lock tender, or lock operator looks after a canal or river lock, operating it and if necessary maintaining it or organizing its maintenance. Traditionally, lock keepers lived on-site, often in small purpose-built cottages. A lock keeper may also be the operator for the lock's

Duties

Lockkeepers were on call 24 hours a day during the boating season. On the

, the lock keepers were required to remove the windlasses from all lock paddles at night, to prevent unauthorized use. But they had to get up and man the lock if a boat came through at night. Lock keepers had to enforce company rules against independent and wily boat captains. In some cases, they had to check waybills that the boats had. They also were responsible for the level (canal pound) by their lock, to fix leaks and other minor repairs. Some lock keepers simply left the job and disappeared.

To help a boat get out of a lock (going downstream) the lockkeeper would sometimes provide a ''swell'', that is, opening the paddle valves (wickets) on the upstream gates so that the rush of water would flush the boat out. Some wily lock keepers would demand money from the boatmen for this "service". If a boat ran aground between locks, they would sometimes ask a passing boat (going upstream) to tell the next lock keeper to give an extra heavy swell, by opening all the wickets on the upstream lock thus raising the water level temporarily, so that they could get unstuck. 160px, Man tending inclined plane 7 East on the Morris Canal The

had inclined planes as well as locks, and the former required keepers also, although one cannot exactly call them "lock keepers" since they did not tend a lock, but an inclined plane which did much of the same function as a lock, lifting or lowering boats from one level to another, albeit with a cradle which carried the boats.

Incidents

There were often conflicts between the boat captains and the lock keepers. In July 1874 on the Chesapeake and Ohio Canal, there was a notorious incident, where the boat's tow line caught and tore the lock railing and the captain of the boat insisted on scrubbing the boat's sides with a broom while still in the lock. The lock keeper demanded that the captain remove the boat from the lock, which he refused. The lock keeper's son opened one of the gates pinning the captain's son against the boat. There was soon a fist fight, and the captain's wife knocked one of the keeper's sons off the boat. Things escalated to rock throwing, clubbing, and the lock keeper's sons returned with a shotgun and revolver, which misfired. When the boat did resume its journey, the lock keeper followed on horseback, all the way to Cumberland (the end of the canal) with a club threatening to settle things. There were plenty of incidents with negligent lock keepers. On September 11, 1895 at Lock 22, the boat ''Excelsior'' arrived, and tried to lock through. The lock keeper was so drunk, he opened the lower gate paddles too early. The boat hit the mitre sill, broke in half, and sank with its 113 tons of coal. Richard A. Moore, the owner of the boat, collected over $1,300 in damages, and the lock keeper was fired. In England, there has been recent controversy over the

Promotions

Many people who began as lock keepers were later promoted in the company. Many district superintendents of the

began as lock keepers, but because of their good reputation, were promoted. These included Elgin and John Y. Young in the 1830s and 1840s, John Lambie in the 1840s. A. K. Stake began at locks 41–41 from 1847 to 1848, Lewis G. Stanhop at locks 41–42 also in 1848, and Overton G. Lowe at Lock 56 when the canal opened to Cumberland — these three individuals were later promoted and continued working for the Canal company well into the 1870s.

Modern locks

Locks on commercial canals are usually power operated. The lock keeper, who no longer lives on site, controls the whole process from a control room overlooking the lock. In the modern age the control of traffic and locks on canals is being centralised. A single control centre can remotely operate several locks and moveable bridges in a wide area, overseeing the process using

As the controller now has overview over the traffic moving through one lock after another, he can anticipate the arrival of boats by turning the lock in advance, having boats wait for another coming from behind to handle them simultaneously, or decide whether to turn a lock empty for a boat going in one direction or to wait for one going in the other direction.
