weirs
Low water dams
Weirs are barriers built across rivers or streams to control water flow.
A weir raises the water level upstream, creating a pool while allowing water to flow over or through it.
Weirs serve various purposes: measuring water flow, diverting water for irrigation, creating fish traps, or powering mills.
