The following reports outline the results of the “Impact of Weirs on Environmental Flows, Water Quality and Fish Passage” project (otherwise known as the “NSW Detailed Weir Review” project) for the catchments of NSW. The 2003 project was funded through the NSW Environmental Trust and allowed for priority setting of weir structures by Department of Primary Industries and Regional Development Fisheries (previously NSW Department of Primary Industries Fisheries). Please note that some of the structures listed in the reports no longer act as fish passage barriers as they have either been removed or have had fishways installed.
