Modeled sand transport, sandbar volumes, and reservoir operations for the Colorado River in Grand Canyon in support of resource impact analysis for Post-2026 reservoir operational alternatives Modeled sand transport, sandbar volumes, and reservoir operations for the Colorado River in Grand Canyon in support of resource impact analysis for Post-2026 reservoir operational alternatives
These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post-2026) Environmental Impact Statement (EIS). These data were compiled to predict the impact of different proposed alternatives for Glen Canyon Dam operations on sand resources, including sand mass balance, sandbar volume, and frequency/duration of controlled...
Copper concentrations and associated morphometric data from brook trout (Salvelinus fontinalis) and copper results from macroinvertebrates and zooplankton at 6 lakes in Sequoia National Park, CA, 2021-2022 Copper concentrations and associated morphometric data from brook trout (Salvelinus fontinalis) and copper results from macroinvertebrates and zooplankton at 6 lakes in Sequoia National Park, CA, 2021-2022
This dataset encompasses a series of files related to a comprehensive ecotoxicology research project conducted in high elevation lakes of the Tokopah Basin in Sequoia National Park. The dataset includes detailed sampling data that reflects the copper concentrations at multiple levels of the food web. This dataset also includes morphometric data for collected fish, biomarkers of fish...
Passive acoustic telemetry detections of Black Carp Mylopharyngodon piceus in the Mississippi River Basin; 2021-2023 Passive acoustic telemetry detections of Black Carp Mylopharyngodon piceus in the Mississippi River Basin; 2021-2023
This dataset represents passively detected locations of acoustic telemetry tagged Black Carp in the Mississippi and Missouri rivers near their confluence. These river segments consisted of both open river and impounded habitat present during observed hydrologic conditions from 2021-2023. Receiver arrays were set in known use areas (determined by active relocations of tagged fish) and set...
