Small artificial impoundments have big implications for hydrology and freshwater biodiversity

Robert Morden et al.

Summary: Headwater streams are crucial for freshwater ecosystems, but the hydrological impacts of small artificial impoundments (SAIs) in these streams have been largely ignored. Using case studies in Australia and the US, it was found that SAIs alter hydrology in a significantly larger number of waterways compared to major dams. This poses a threat to the diverse and endemic biota found in smaller streams.

A machine learning approach to identify barriers in stream networks demonstrates high prevalence of unmapped riverine dams

Brian P. Buchanan et al.

Summary: Restoring stream ecosystem integrity by removing unused or derelict dams has become a global priority for watershed conservation. A machine learning approach was developed and tested to identify unmapped dams, revealing that existing dam inventories often underestimate the true number of dams by 80-94%. The machine learning method can provide an accurate and scalable means of identifying unmapped dams, guiding efforts to develop more accurate dam inventories for better management.

Reducing adverse impacts of Amazon hydropower expansion

Alexander S. Flecker et al.

Summary: The proposed hydropower dams in the Amazon region require strategic evaluation due to the various ecosystem services provided by the river basin. Using multiobjective optimization, this study identifies portfolios of sites that minimize impacts on different aspects while achieving energy production goals. The uncoordinated dam-by-dam expansion has led to the loss of ecosystem service benefits, highlighting the importance of considering diverse environmental impacts and cooperation among Amazonian nations.

Operational methods for prioritizing the removal of river barriers: Synthesis and guidance

Carlos Garcia de Leaniz et al.

Summary: Barrier removal is an effective method for restoring river connectivity, but resources for defragmenting rivers are limited, requiring a prioritization strategy. The effectiveness of barrier removal depends on barrier typology, location, size, and impacts, with a focus on targeting barriers with high fragmentation impacts. Prioritization methods can be reactive or proactive, local or larger-scale, and formal or informal, with a hybrid approach likely to be the most effective. Accuracy in stream networks, barrier coordinates, and numbers is crucial for successful barrier removal projects, with ground truthing and predictive modeling as potential solutions for uncertainties.

Global hydropower expansion without building new dams

Kayla Garrett et al.

Summary: Transitioning to renewable energy sources requires minimizing environmental impacts of new dam construction, while maximizing benefits of hydropower through upgrading existing infrastructure. This approach could potentially increase global hydropower capacity by up to 9%, offsetting biodiversity impacts and reducing construction and transmission costs.

Safeguarding migratory fish via strategic planning of future small hydropower in Brazil

Thiago B. A. Couto et al.

Summary: This study quantified the trade-offs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil, revealing that SHPs cause fourfold greater average connectivity losses compared to LHPs. The fragmentation by SHPs is projected to increase by 21% in the future, affecting two-thirds of the 191 migratory species assessed. Pareto frontier analysis identified future dam portfolios that could halve the number of hydropower plants required to deliver the same energy-generation capacity, while reducing river fragmentation and protecting undammed basins.

The Use of Barriers to Limit the Spread of Aquatic Invasive Animal Species: A Global Review

Peter E. Jones et al.

Summary: Aquatic invasive species pose a significant threat to freshwater biodiversity, leading to the increased use of exclusion barriers as a management strategy. However, the effectiveness of these barriers is context dependent and can impact native organisms. Global studies show that barriers have been successful in limiting the passage of AIS, but more research is needed to understand their long-term impacts on native species and to improve their effectiveness as a management tool.

Selective effects of small barriers on river-resident fish

Peter E. Jones et al.

Summary: The study revealed that the passage rates of river-resident fish when faced with obstacles varied, with brown trout's passage rate being influenced by body length and boldness. Barriers may have selective effects on fish, leading to shifts in community composition.

Ecological impacts of run -of -river hydropower plants ? Current status and future prospects on the brink of energy transition

Alban Kuriqi et al.

Summary: The widespread perception of small run-of-river hydropower plants as renewable energy sources has led to their global proliferation, but such schemes may have negative impacts on fluvial ecosystems. Different types of small run-of-river hydropower schemes have varying ecological impacts, with diversion weir and pondage schemes being less eco-friendly compared to dam-toe schemes. Environmental flows are crucial for ecosystem conservation in rivers affected by hydropower operations.

A review of hydropower plants in Romania: Distribution, current knowledge, and their effects on fish in headwater streams

Gabriela Costea et al.

Summary: Hydropower is booming in southeast Europe, with Romania having between 545 and 674 hydropower plants. Many of these plants are located in protected areas or water bodies with good or very good ecological status. However, the construction of hydropower plants has significantly impacted fish populations in Romania's headwater streams, leading to the disappearance of certain species. Efforts to mitigate these environmental impacts are lacking, posing a threat to aquatic biodiversity in the country.
