Data

These spatial and tabular data were compiled to have a decade-long record of the water usage in the riparian corridor and the wetlands near Phoenix, Arizona called the Tres Rios area to observe the effect of riparian and wetland health as characterized by vegetation greenness and its water use or evapotranspiration. The objective of our study was to quantify evapotranspiration (ET, in...

Bathymetric, topographic, and grain-size data were collected in April 2019 along a 58.6 mile (94.3 kilometer) reach of the Colorado River in Grand Canyon National Park, Arizona. The study reach begins at river mile 30, about 2.5 miles above South Canyon, and ends at river mile 88 at the upstream boundary of the Bright Angel Rapid (Phantom Ranch boat beach). This reach spans two...

These data were collected as part of a U.S. Geological Survey effort to resurvey the Marble Canyon and Bridge Canyon dam sites on the Colorado River in Grand Canyon National Park. The objective of our study was to resurvey these dam sites to document the changes in sediment storage that have occurred since the original 1940s–1950s Bureau of Reclamation surveys. The data in this release...

These data were simulated to use in a conceptual paper that explores the impacts of temperature and drifting invertebrate prey assemblages on Rainbow Trout. Objectives of our study were to examine how warming-induced changes in invertebrate prey production and size structure may impact the growth rate and maximum body size of Rainbow Trout in freshwater ecosystems using drift-foraging

These data were compiled for the National Park Service. Objective(s) of our study were to resurvey previously established cross sections on the Green River in Browns Park, Colorado and Utah, to document changes in channel width, depth, and cross-sectional area. In addition, new cross sections were established in areas that lacked previously surveyed cross sections. These data represent...

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 document over a century of plant community change on the Colorado Plateau (CP) using repeat photography (1910-2016). Photos were taken across a 3100 square kilometer area on the CP largely in areas administered by the NPS and Bureau of Land Management (BLM), including (but not limited to) areas now within Arches National Park and Canyonlands National Park; Glen Canyon National

These data were compiled to assess species performance for 59 native grass, forb, and shrub species that were seeded and (or) planted across 20 RestoreNet sites in the Southwest US. Objectives of our study were to assess species performance within and across ecoregions, across revegetation methods (seeding or outplanting greenhouse-grown seedlings), and by growth form (grass, forb, or...

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 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). 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...

These data were compiled to investigate competitive interactions between Pleurphis jamesii and other herbaceous plants in a semiarid grassland community. The objectives of our study were to determine whether selective mortality of either C3 or C4 herbaceous plants led to changes in (1) soil moisture during the growing season, (2) water use by Pleuraphis jamesii during the growing season...
