weir


weir
1) nets or fences set in streams or along the coast to direct fish into a holding container for easy capture. Some weirs take advantage of the falling tide to capture fish; others catch upstream migrating adults; others strain fish out of the water on a screen through which the water drains, or into bags suspended from the screen; along a chute with a bag or box at its end; or in an arched weir, higher in the middle to direct water laterally, to the shore ends where a trap awaits the fish
2) a dam in a river to stop, raise and divert the water, for the purpose of conducting it to a mill, forming a fishpond, etc. When uncontrolled, the weir is termed a fixed-crest weir. Other types of weirs include broad-crested, sharp-crested, drowned, and submerged
3) a bank or levee to hold a river in its bed or to direct it to a new bed
