  • Klamath Dam Removal: A Key Step in Freshwater Restoration and Protection Goals

    ›

    The Klamath River Dam removal, slated for early 2024, is a significant milestone in the journey towards bringing back healthy rivers in the United States. This action will restore nearly 300 miles of river habitat in the Klamath and its tributaries across Southern Oregon and Northern California, allowing salmon, a critical source of economic and nutritional value for the local communities, to return. As the world’s largest dam removal and river restoration project in history, this project will have lasting impacts on the health of this river and represents an opportunity for building momentum to continue global river protection and restoration.

    Aerial view of Manso Dam  The Manso Dam is a hydroelectric dam on the Manso River, a tributary of the Cuiabá River, in the state of Mato Grosso, Brazil.

    Connected and healthy rivers deliver diverse benefits that are often overlooked: freshwater fish stocks that improve food security for hundreds of millions of people, nutrient-rich sediment that supports agriculture and keeps deltas above rising seas, floodplains that help mitigate the impact of floods, and a wealth of biodiversity. Navigating Trade-Offs Between Dams And River Conservation, a new report in the journal, Global Sustainability, reveals that if all proposed hydropower dams are built, over 260,000 km of rivers (160,000 miles), including the Amazon, Congo, Irrawaddy, and Salween mainstem rivers, will lose free-flowing status.

    Last April, Vice President Kamala Harris visited the Upper San Leandro treatment plant in Oakland, her Californian hometown. The American Jobs Plan, she told her constituency, will deliver over a hundred billion dollars for the upgrade of U.S. water supply infrastructure. In truth, the investment plan, one of the largest in a generation, is far more ambitious than that. Across all proposed expenditures, it includes not just the upgrade of all water piping, but also remediation, flood protection, ecosystem restoration, and the climate proofing of economic activities. All these initiatives place water at the heart of recovery and resilience.

    The travails of the last year, when a bat virus infected humans and turned the world upside down, were an unfortunate reminder of the inseparable ties between society and the natural environment.

    So it is with water, which will again this year direct the course of history, through events small and large.

    What are the large events to pay attention to? What are the trends and flashpoints?

    The Grand Ethiopian Renaissance Dam (GERD) poses numerous challenges for the Nile river basin, but it also presents an opportunity for regional collaboration and shared prosperity, said Aaron Salzberg, Director of the Water Institute at the University of North Carolina and Wilson Center Global Fellow, at a recent event hosted by the University of North Carolina’s Center for Middle East and Islamic Studies.

    Dams can be a double-edged sword, said Aaron Salzberg, a Wilson Center Global Fellow, Director of the Water Institute at the University of North Carolina, and former Special Coordinator for Water Resources for the U.S. Department of State. He spoke in a recent episode of Wilson NOW about the Grand Ethiopian Renaissance Dam, which will become Africa’s largest hydroelectric dam, once it’s fully operational.

    Southern Africa has experienced drought-flood cycles for the past decade that strain the ability of any country to properly manage water resources. This dynamic is exacerbated by human drivers such as the heavy reliance of sectors such as mining and agriculture on groundwater and surface water, as well as subsistence agriculture in rural areas along rivers. These factors have progressively depleted natural freshwater systems and contributed to an accumulation of sediment in river systems. In a region where two or more countries share many of the groundwater and surface resources, water security cuts across the socioeconomic divide and is both a rural and urban issue. For example, the City of Cape Town had to heavily ration all water uses in 2017 and 2018, as its dams were drying up.

    New technology, however, brings new opportunities for improved water governance. In Southern Africa, university researchers and government agencies are joining with international development groups and the private sector to explore how big data analytics can improve the management of aquifers that are shared by two or more countries.

    Rising tensions between Egypt and Ethiopia over construction of the Grand Ethiopian Renaissance Dam (GERD) have led to speculation that there could be a war over water. When completed, the dam will be the largest in Africa. And it will give Ethiopia control over the Blue Nile River, a major source of Egypt’s water.
