U.S. Fish and Wildlife Service Argos GPS Satellite Tracking Data for Lesser Yellowlegs (Tringa flavipes) U.S. Fish and Wildlife Service Argos GPS Satellite Tracking Data for Lesser Yellowlegs (Tringa flavipes)
This data package contains location data collected by the Argos System (CLS America, Inc.) from satellite transmitters attached to 116 Lesser Yellowlegs captured at multiple sites across their breeding and nonbreeding range in North America, 2018-2021. The raw data were processed to accomplish two goals: 1) flag implausible location and 2) remove locations within Joint Base Elmendorf...
Predicted recreation economics under different management scenarios for Lake Powell releases Predicted recreation economics under different management scenarios for Lake Powell releases
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 different future Interim Guidelines sEIS and LTEMP sEIS alternatives. These data include monthly impacts in nominal 2022 dollars. These data were created for operations...
Forecasting smallmouth bass invasion under different management scenarios for Lake Powell releases, 2024-2027 Forecasting smallmouth bass invasion under different management scenarios for Lake Powell releases, 2024-2027
These data were compiled for modeling efforts of Bureau of Reclamation National Environmental Policy Act (NEPA) analyses for the Colorado River in Grand Canyon, Arizona. Objective(s) of our study were to forecast water temperature, smallmouth bass population growth rate, and smallmouth bass entrainment rates under different water management scenarios. These data represent forecasted...
Dissolved oxygen predictions for releases from Lake Powell under different management scenarios for Lake Powell releases Dissolved oxygen predictions for releases from Lake Powell under different management scenarios for Lake Powell releases
Dissolved oxygen estimates were generated to help understand how different alternative management scenarios may affect the likelihood of low dissolved oxygen in Glen Canyon Dam releases. The study aimed to examine the effects of different management alternatives on late summer and early fall dissolved oxygen concentrations in Glen Canyon Dam releases. The estimates represent estimates of...
Subaerially exposed river sand and reservoir shoreline modelling for Lake Powell releases and changes in Lake Powell and Lake Mead storage Subaerially exposed river sand and reservoir shoreline modelling for Lake Powell releases and changes in Lake Powell and Lake Mead storage
These data were compiled to evaluate impacts of different reservoir management scenarios on sand exposure for aeolian landscape and cultural site resources. Objective of our study was to predict areas of dry, bare Colorado River sand as a function of different management alternative scenarios. These data represent predictions of dry, bare sand for the reach of the Colorado River between...
Plant habitat suitability modeling for the Colorado River in Grand Canyon, Arizona under different management scenarios for Lake Powell releases Plant habitat suitability modeling for the Colorado River in Grand Canyon, Arizona under different management scenarios for Lake Powell releases
These data were compiled to assess potential impacts of altered operations of Glen Canyon Dam on riparian plant resources. Objective(s) of our study were to quantify potential responses of specific vegetation metrics. These data represent predicted changes in vegetation metrics based on the data in the Interim Guidelines and LTEMP_SEIS folders. These data were collected in Grand Canyon...
