under bridge Grave ]] , Japan , used to power a Waterwheel .]] A sluice is a water channel that is controlled at its head by a gate. For example, a '''millrace''' is a sluice that channels water toward a Water Mill . A sluice gate is traditionally a wooden or metal plate which slides in grooves in the sides of the channel. Sluice gates are commonly used to control water levels and flow rates in River s and Canal s. They are also used in wastewater treatment plants and to recover minerals in Mining operations. OPERATION Raising a sluice gate allows water to flow under it. (The term ''sluice gate'' refers to any gate that operates by allowing water to flow under it.) When a sluice gate is fully lowered, water sometimes spills over the top, in which case the gate operates as a Weir . Usually a mechanism drives the sluice gate up or down. This may be a simple, hand-operated, worm drive or Rack And Pinion Drive , or it may be electrically or Hydraulically powered. The gates of a Lock may work in a way similar to the way a sluice gate works, but traditional canal lock gates are hinged to swing like double doors. TYPES OF SLUICE GATES
