Abstract

A fish way for installation on the bed of a water-flow comprising a perforate hollow weir 1 defining a substantially enclosed space, with an upstream surface and a downstream surface and having a base adapted to the bed of a water-flow to define a chamber. There are two or more perforations in the upstream surface and one or more perforations in the downstream surfaces. The upstream and downstream surfaces each contain perforations 6. The perforations in the upstream surface provide for water inflow into the chamber at a rate greater than water outflow from the perforations in the downstream surface of the weir
