Christopher J. Shipway, Jamie A. Duberstein, William H. Conner, Ken Krauss, Gregory E. Noe, Stefanie L. Whitmire
2024, Forests (15)
Upper estuarine forested wetlands (UEFWs) play an important role in the sequestration of atmospheric carbon (C), which is facilitated by their position at the boundary of terrestrial and maritime environments but threatened by sea level rise. This study assessed the change in aboveground C stocks along the estuarine–riverine hydrogeomorphic...

Thomas J. Williams, Greg S. Totzke
2024, Scientific Investigations Report 2024-5078
The Kansas River is an essential water resource that provides drinking water to more than 950,000 people in northeastern Kansas. Water suppliers that rely on the Kansas River as a water-supply source use physical and chemical water-treatment strategies to remove contaminants before distribution. Water District No. 1 of Johnson County,...
Forest cover lessens hurricane impacts on peak streamflow
Jazlynn S. Hall, Martha A. Scholl, James B. Shanley, Serena Matt, Maria Uriarte
2024, Hydrological Processes (38)
Cyclonic storms (i.e., hurricanes) are powerful disturbance events that often cause widespread forest damage. Storm-related canopy damage reduces rainfall interception and evapotranspiration, but impacts on streamflow regimes are poorly understood. We quantify streamflow changes in Puerto Rico following Hurricane Maria in September 2017, and evaluate whether forest cover and storm-related...

2024, North American Journal of Fisheries Management (44) 987-1007
ObjectiveIn a changing climate, the effects of air temperature, precipitation, and groundwater on water temperature and thermal habitat suitability for Gulf Sturgeon Acipenser desotoi, listed as threatened under the U.S. Endangered Species Act, are not well understood. Hence, we incorporated these factors into thermal habitat models to...

Ramon C. Naranjo, Anjela Bubiy
2024, Open-File Report 2024-1045
Residents of Carson Valley, Douglas County, Nevada, rely on the basin-fill alluvial aquifer underlying the valley for drinking water. Since the 1980s, groundwater levels and water-quality data have been collected to monitor the status of the aquifer system and to assist in planning efforts to address current (2024) and future...
Declining reservoir reliability and increasing reservoir vulnerability: Long-term observations reveal longer and more severe periods of low reservoir storage for major United States reservoirs
Caelan Simeone, John C. Hammond, Stacey A. Archfield, Dan Broman, Laura Condon, Hisham Eldardiry, Carolyn G. Olson, Jen Steyaert
2024, Geophysical Research Letters (51)
Hydrological drought is a pervasive and reoccurring challenge in managing water resources. Reservoirs are critical for lessening the impacts of drought on water available for many uses. We use a novel and generalized approach to identify periods of unusually low reservoir storage—via comparisons to operational rule curves and historical patterns—to...

2024, JGR Biogeosciences (129)
Decadal scale lake drying in interior Alaska results in lake margin colonization by willow shrub and graminoid vegetation, but the effects of these changes on plant production, biodiversity, soil properties, and soil microbial communities are not well known. We studied changes in soil organic carbon (SOC) and nitrogen (N) storage,...

Wendy B. Welch, Andrew J. Long, editor(s)
2024, Scientific Investigations Report 2024-5026-D-E
Groundwater flow in the active model area (AMA) was simulated using a groundwater-flow model. A steady-state model version of the model simulates equilibrium conditions, and a transient model version simulates monthly variability. The model corresponds to the physical and temporal dimensions of the conceptual model and groundwater budget. The steady-state...

Landscape-scale modeling to forecast fluvial-aeolian sediment connectivity in river valleys
Alan Kasprak, Joel B. Sankey, Joshua Caster
2024, Geophysical Research Letters (51)
Sedimentary landforms on Earth and other planetary bodies are built through scour, transport, and deposition of sediment. Sediment connectivity refers to the hypothesis that pathways of sediment transport do not occur in isolation, but rather are mechanistically linked. In dryland river systems, one such example of sediment connectivity is the transport of...

Testing tree-ring cellulose δ18O with water isotopes for Holocene lake δ18O interpretations in the central Rocky Mountains USA
Lesleigh Anderson, M. Alisa Mast, Rebecca Lynn Brice, Max Berkelhammer
2024, The Holocene
Stable isotopes of water preserved in geologic archives, primarily as oxygen (δ18O), have proven critical for documenting Earth’s climatic and hydrologic systems past and present. However, timescale differences of water isotope inputs to proxy systems and the signal embedded in long paleorecords often confound translation to observed hydroclimatic metrics. Here,...

Andrew S. Gendaszek, Anya Clare Leach, Kristin L. Jaeger
2024, Preprint
Water temperature is a primary control on the occurrence and distribution of cold-water species. Rivers draining Mount Rainier in western Washington, including the White River along its northern flank, support several cold-water fish populations, but the spatial distribution of water temperatures, particularly during late-summer base flow between August and September,...

Effects of temporal hydrologic shifts on the population biology of an endangered freshwater fish in a dryland river ecosystem
Jonathan Q. Richmond, Philip Robert Gould, Jennifer Pareti, Andrew Aitken, Eric Morrissette, Adam R. Backlin, Chris Dellith, Robert N. Fisher
2024, Aquatic Conservation: Marine and Freshwater Ecosystems (34)
Species occupying dryland river ecosystems often experience “boom-and-bust” demographic cycles that coincide with shifts in habitat availability. Knowing whether declines are within natural thresholds versus those caused by acute human disturbance is critical for managing protected species. We investigated temporal shifts in abundance and habitat use of an endangered population...

Joseph J. Kennedy, Henry M. Johnson, Stephen B. Gingerich
2024, Scientific Investigations Report 2024-5033
The annual maximum extent of surface water in Klamath Marsh has naturally fluctuated in response to periods of wet and dry conditions in the surrounding basin. Field observations during the 2010s indicate that the annual maximum extent of surface water has been declining and the marsh is not responding to...

Connor P. Newman, Eric Humphrey, Matthias Brennwald, W. Payton Gardner, Kelli M. Palko, Michael Gooseff, Kip Solomon
2024, Journal of Hydrology (640)
Discharge of deeply sourced groundwater to streams is difficult to locate and quantify, particularly where both discrete and diffuse discharge points exist, but diffuse discharge is one of the primary controls on solute budgets in mountainous watersheds. The noble gas helium is a unique identifier...
