Description

A barrier built across a river, sometimes to divert water for industrial purposes. Water can still flow over the top.

See also:

• waterway=dam for a bigger barrier.

How to map

To map a small weir add a node along a river and tag it waterway=weir, if the weir has a name tag it name=*. If the Weir is long enough to be mapped as a way, create a way along the length of the weir and tag it waterway=weir, again add a name=* if it is known.
