Many obsolete barriers harm Europe’s rivers<\/h3>\n

River continuity is key to improving the ecological status of Europe\u2019s water bodies. However, very few free-flowing rivers remain and the barriers in them cause significant pressures for about 20 % of Europe\u2019s surface water bodies. A European Environment Agency (EEA) briefing, published today, looks at the issue of river barriers and their impact on ecosystems.<\/p>\n

Single large barriers, such as dams, or a series of small structures alter a river\u2019s natural flow and cause pressures on fish and other species as well as their habitats. Based on recent studies, it can be estimated that there are\u00a0more than one million barriers in European rivers<\/strong>\u00a0and that\u00a0about 10 % of them are obsolete<\/strong>.<\/p>\n

According to the EEA briefing,\u00a0restoration measures<\/strong>\u00a0aim to improve river continuity in several parts of Europe. Common measures include removing barriers, helping fish to migrate and re-establishing sediment transport.<\/p>\n
