Data from: Integrating ecological niche and hydrological connectivity models to assess the impacts of hydropower plants on an endemic and imperiled freshwater turtle
<p>We built this dataset to assess the impacts of hydropower plants on the distribution of an endemic and imperiled freshwater turtle with very unique ecological requirements, the Williams' side-necked turtle (<em>Phrynops</em> <em>williamsi</em>). To prevent and mitigate impacts, we prioritized sites for species conservation by classifying planned HPP locations according to their predicted adverse effects on species distribution. The dataset has two files: i) species occurrence records and ii) hydropower plant data. The first dataset was fully built by the authors and the second was modified from the Brazilian Electricity Regulatory Agency (ANEEL) georeferenced data system.</p>

Data from: Migratory passage structures at hydropower plants as potential physiological and behavioural selective agents
Anthropogenic activities affect fish populations worldwide. River dams have profound impacts on ecosystems by changing habitats and hindering migration. In an effort to counteract such effects a diversity of mitigation measures has been installed at hydroelectric power plants. Still, not all individuals in a population use these measures, creating potentially strong selection processes at hydroelectric power plants. Especially, during migration, when fish can get heavily delayed or pass through a hydropower turbine, facing increased mortality compared to those using a safe bypass route. In this study, we quantify migration route choices of descending wild PIT-tagged Atlantic salmon smolts released upstream from a hydroelectric plant. We demonstrate how only a few meters' displacement of bypass canals can have a large impact on the fish guidance efficiency. The proportion of fish using the bypasses increased when water was released in surface gates closer to the turbine intake. During a period of low fish guidance efficiency, we observed two different smolt migratory strategies. While some individuals spent little time in the forebay before migrating through the turbine tunnel, others remained in the forebay. We suggest that these groups represent different behavioural types, and that sub-optimal mitigation measures at hydropower intakes may therefore induce strong selection on salmon behavioural traits. The ultimate outcome of these selection mechanisms is discussed in light of potential trade-offs between turbine-migration mortality costs and optimal sea-entrance timing survival benefits.
Data from: Managing hydropower dam releases for water users and imperiled fishes with contrasting thermal habitat requirements
1) The construction of dams on large rivers has negative impacts on native species. Environmental flows have been proposed as a tool to mitigate these impacts, but in order for these strategies to be effective they must account for disparate temperature and flow needs of different species. 2) We applied a multi-objective approach to identify tradeoffs in dam release discharge and temperature for imperiled warm- and cold-water fishes while simultaneously meeting the needs of human water users. 3) Using the Sacramento River (California, USA) as a case study, our model suggests that current management aimed at conserving an endangered cold-water species (winter-run Chinook salmon; Oncorhynchus tshawytscha) and providing high discharge for downstream water users has detrimental impacts on a threatened warm-water species (green sturgeon; Acipenser medirostris). 4) We developed an optimal dam release scenario that can be used to meet the needs of salmon, sturgeon, and human water users. Our results show that dam releases can be managed to successfully achieve these multiple objectives in all but the most severe drought years. Synthesis and applications This study shows that managing dam releases to meet the needs of a single species can have detrimental effects on other native species with different flow and temperature requirements. We applied a multi-objective approach to balance environmental requirements of multiple species with the needs of human water users. Our findings can be used to guide management of Shasta Dam and our approach can be applied to achieve multi-object management goals in other impounded rivers beyond California's Sacramento River.
