What does sluicegate mean?
A sluicegate is a movable gate positioned in a sluice, canal, or other water channel to regulate the volume and direction of water flowing through it. Raising the gate can allow water to pass, while lowering or closing it restricts or stops the flow. The term is chiefly used in civil engineering, irrigation, drainage, and canal management, so it belongs to specialized rather than general everyday vocabulary. A sluicegate is distinguished from a sluice itself: the sluice is the channel or passage, whereas the sluicegate is the movable barrier within it. Although the mechanism can be simple, its operation may involve substantial water pressure, making careful control and maintenance important. The word is also useful as an example of a transparent English compound, with sluice and gate identifying both the type of structure and its controlling component.
nounA gate or movable barrier in a sluice or artificial water channel, used to regulate the flow of water. In some contexts, it refers to the gate assembly itself.
- A gate in a sluice or water channel that regulates the flow of water.
"The crew raised the sluicegate to let water into the irrigation channel."
"Engineers inspected the sluicegate before opening it for the flood season."
"The old canal sluicegate was installed with a hand-operated lifting mechanism."
The standard plural adds -s.
"Several sluicegates were opened to release water from the reservoir."
One small gate can release a torrent of water: the sluicegate is engineering’s pressure-release valve in an open channel.

Where does sluicegate come from?
The compound combines sluice and gate, both of which are English words with older histories. Sluice entered English from Old French and ultimately Latin, referring to a channel for carrying or releasing water, while gate comes from Old English gatu and originally referred to an opening in a barrier. The compound therefore literally identifies a gate associated with a sluice or water channel.
How sluicegate is actually used
A technical civil-engineering term rather than everyday vocabulary. It is chiefly used in descriptions of canals, dams, irrigation systems, drainage works, and other hydraulic installations.
Easily confused with sluicegate
A sluice is the artificial channel or passage through which water flows, whereas a sluicegate is the gate that controls that flow.
