Suspended Sediment Conditions to Hyporheic Dissolved Oxygen and Fine Sediment Deposition in Salmonid Spawning Habitat Below an Irrigation Dam, Park County, Wyoming Suspended Sediment Conditions to Hyporheic Dissolved Oxygen and Fine Sediment Deposition in Salmonid Spawning Habitat Below an Irrigation Dam, Park County, Wyoming
We quantified the effects of dam sediment management operations on downstream salmonid spawning habitat during two fall water-level drawdown periods: an experimental drawdown leading to sediment release or a typical slower drawdown intended to minimize release of sediment. The experimental drawdown increased deposited fine sediment and decreased hyporheic dissolved oxygen levels. However...
Soil texture and hydraulic conductivity at a 1-kilometer resolution for the Contiguous United States based on 30-meter resolution data from the Polaris database.

The U.S. Geological Survey (USGS) Integrated Water Availability Assessments (IWAAs) Program is designed to deliver nationally consistent assessments of water supplies for human and ecological needs, and to identify factors that influence water availability. In support of these studies, a National-Extent Hydrogeologic Framework (NEHF) is under development. The NEHF is a three-dimensional...
Sabine Refuge Marsh Creation (CS-28): 2021 land-water classification Sabine Refuge Marsh Creation (CS-28): 2021 land-water classification
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...
Large-Scale Marsh Creation Project – Upper Barataria Component (BA-0207): 2021 land-water classification Large-Scale Marsh Creation Project – Upper Barataria Component (BA-0207): 2021 land-water classification
The Louisiana Coastal Protection and Restoration Authority and the Natural Resource Damage Assessment (NRDA) develop restoration plans in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions...
Plant responses to and microbial community composition of greenhouse soils growing Phragmites australis Plant responses to and microbial community composition of greenhouse soils growing Phragmites australis
To determine how native and non-native lineages of Phragmites australis affect and respond to soil bacteria, fungi and oomycetes, we collected live rhizomes, seeds and soil from native and non-native lineages of Phragmites from 10 sites within Michigan and Ohio, USA. We propagated these field-collected samples to carry out a reciprocal-transplant plant-soil feedback experiment with...
Roads within 13 tracts of the Lower Rio Grande Valley National Wildlife Refuge in South Texas: 2004 and 2024 Roads within 13 tracts of the Lower Rio Grande Valley National Wildlife Refuge in South Texas: 2004 and 2024
Border barrier construction along the USA-Mexico border has resulted in an increase in border patrol and construction vehicle activity near and within the Lower Rio Grande Valley Wildlife Refuge (LRGVNWR) system, which is located along the Rio Grande River near the USA-Mexico border in Cameron, Hidalgo, and Starr counties in south Texas (USA). This data release characterizes road...
