Quick Summary

A sluice is an artificial channel or passage designed to control the flow of water. It can be a stream used to drain or carry off surplus water, or a body of water held back by a floodgate. A key component of a sluice is the sluice gate, which is a sliding gate used to stop or regulate the water flow. These gates are essential in various engineering applications, such as in locks for canals, where they help vary water levels to raise or lower boats. Sluices can also be long, inclined troughs used in mining, particularly for catching gold.1234
