Rivers, canals and boats: locks, weirs, water-mills, barges and how not to tip a rowing boat, sentence 14

A weir is a low wall across a river that keeps the water deep upstream for boats and can send water to a mill; below it the water churns round and round and can hold a swimmer under, so never swim near a weir.

Who acts: weir, river, water · What happens: be, keep, send, churn, hold under, not swim · To what, where: low wall, river, water, mill, swimmer, weir
