Data

This data release compiles the inputs and outputs for a nitrogen mass balance model for nine small agricultural watersheds within the Chesapeake Bay nontidal watershed. Data inputs include annual nonpoint source nitrogen input, plant uptake, and output, and total discharge from 1985-2020 for each of the agricultural watersheds. Data inputs also include median groundwater age used to...

Tools that accurately and reliably forecast potential ecological responses to both climate variability and natural resource management can improve the decision process, especially for landscapes where decision points occur iteratively across time. In the Everglades, natural resource practitioners use models and decision support tools to assist their evaluations of restoration progress...

Machine learning (ML) models were used to forecast streamflow drought from 1 to 13 weeks into the future at more than 3,000 streamgage locations across the conterminous United States. Long short-term memory [LSTM] neural network models were used to predict weekly streamflow percentiles with independent models for each forecast horizon. In this data release we specifically include an LSTM...

This data release contains predictions of stream biological condition as defined by the Chesapeake basin-wide index of biotic integrity for stream macroinvertebrates (Chessie BIBI) as well as prediction of the percentage of the benthic macroinvertebrate assemblage as 1) Ephemeroptera, Plecoptera, Trichoptera less Hydropsychidae, 2) Ephemeroptera, and 3) Clingers using Random Forest...

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 outputs from models that estimate annual minimum dissolved oxygen and daily water temperature in the Colorado River below Glen Canyon Dam. The objective of our study was to predict water temperatures and...

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 economic impacts to angling in Glen Canyon and whitewater rafting in Grand Canyon. The objective of our study was to estimate recreation impacts, or changes in consumer surplus, under...

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). Specifically, these data present modeled risks to paleontological and cultural resource preservation based on projected reservoir water level fluctuations between December 2026 and December 2060 within Lake Powell and...

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 used to illustrate how six operational strategies (proposed alternatives) for Glen Canyon Dam could affect riparian plant communities along the Colorado River between Glen Canyon Dam and Lake Mead. The...

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...

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 outputs from models that estimate annual smallmouth bass entrainment through Glen Canyon Dam and annual smallmouth bass population growth rate (lambda) in the Colorado River below Glen Canyon Dam. The...

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 used to illustrate how six operational strategies (one baseline and 5 alternatives) could affect subaerial shoreline exposure and potential dust emissions at the Lake Powell and Lake Mead reservoirs. The...

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 used to illustrate how eight operational strategies (one baseline and 5 alternatives) for Glen Canyon Dam could affect sand exposure for aeolian landscape and cultural site resources within Grand Canyon...
