2024, Scientific Investigations Report 2024-5055
The U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, updated low-streamflow statistics for New York, excluding Long Island and including hydrologically connected watersheds in bordering States, for the first time since 1972. Historical daily streamflow data for active and inactive gages were considered for...
Environmental drivers and spatial patterns of antibiotic-resistant, enteric coliforms across a forest–urban riverscape
Angela M Klock, Christian E. Torgersen, Marilyn C Roberts, Daniel J Vogt, Kristiina A Vogt
2024, Freshwater Science (43) 231-249
Antibiotic resistant bacteria are prevalent environmental contaminants in freshwaters, and antibiotic resistance genes circulate throughout the urban water cycle. The increase of antibiotic resistant pathogens threatens public health through direct and indirect exposure, and natural resource managers need information on the spatial...
Capelin on the rebound: Using seabird diets to track trends in forage fish populations
Mayumi L. Arimitsu, Caitlin Elizabeth Marsteller, John F. Piatt, Scott Hatch, Shannon Wheland
2024, Newsletter
Capelin are cold-water forage fish that respond rapidly to fluctuating ocean temperatures. They are prized food for seabirds and other marine predators in Alaska. Researchers have monitored seabird diets at Middleton Island for decades to make connections between changes in abundance of predators and their prey. During a prolonged marine...

Mandy L. Stone, Casey J. Lee, Teresa J. Rasmussen, Thomas J. Williams, Ariele R. Kramer, Brian J. Klager
2024, Open-File Report 2024-1049
The U.S. Geological Survey (USGS) Kansas Water Science Center (KSWSC) has published time-series computations of water-quality concentrations and loads based on in situ sensor data since 1995. Water-quality constituent concentrations or densities are computed using regression models that relate in situ sensor values to laboratory analyses of periodically collected samples....

P. Hensel, Donald R. Cahoon, Glenn R. Guntenspergen, L. G. Mitchell, M. Whitbeck, Galen Scott
2024, Estuaries and Coasts (47) 2094-2105
We compared elevation trajectories from 14 rod surface elevation table (RSET) stations and 60 real-time kinematic (RTK) global positioning system (GPS) transects within the Blackwater National Wildlife Refuge (BNWR) from 2010–2013. The results were similar, 7.3 ± 0.9 (mean ± standard error; RSET) versus 6.2 ± 0.6 mm year−1 (RTK) (P = 0.216), and were greater than relative sea level rise...

2024, Hydrological Sciences Journal (69) 1387-1398
Low-flow period properties, including timing, magnitude, and duration, influence many key processes for water resource managers and ecosystems. We computed annual low-flow period duration and timing metrics from 1951 to 2020 for 1032 conterminous United States (CONUS) streamgages and analyzed spatial patterns, trends through time, and relationships to climate. Results...

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...

Austin K. Baldwin, James Willacker, Branden L. Johnson, Sarah E. Janssen, Collin A. Eagles-Smith
2024, Environmental Science & Technology (58) 14396-14409
The increasing frequency and severity of wildfires are among the most visible impacts of climate change. However, the effects of wildfires on mercury (Hg) transformations and bioaccumulation in stream ecosystems are poorly understood. We sampled soils, water, sediment, in-stream leaf litter, periphyton, and aquatic invertebrates in 36 burned (one-year post...

Joseph Rabaey, Meredith Holgerson, David Richardson, Mikkel R. Andersen, Sheel Bansal, Lauren E Bortolotti, James Cotner, Daniel Hornbach, Kenneth T. Martinsen, Eric Moody, Olivia F. Schloegel
2024, Geophysical Research Letters (51)
Ponds, wetlands, and shallow lakes (collectively “shallow waterbodies”) are among the most biogeochemically active freshwater ecosystems. Measurements of gross primary production (GPP), respiration (R), and net ecosystem production (NEP) are rare in shallow waterbodies compared to larger and deeper lakes, which can bias our understanding of lentic ecosystem processes. In...

Denielle M. Perry, Sarah J. Praskievicz, Ryan McManamay, Alark Saxena, K. C. Grimm, Nicholas Zegre, Lucas Bair, Benjamin L. Ruddell, Richard Rushforth
2024, WIREs Water (11)
The United Nations' Convention on Biological Diversity set forth the 30 × 30 target, an agenda for countries to protect at least 30% of their terrestrial, inland water, and coastal and marine areas by 2030. With <6 years to reach that goal, riverine conservation professionals are faced with the difficult decision of prioritizing...
Genetic origins of a resurging lake whitefish, Coregonus clupeaformis, population in the Detroit River, Laurentian Great Lakes
Wendylee Stott, Robin L. DeBruyne, Edward F. Roseman
2024, International Journal of Limnology (60)
The Detroit River connects Lake Huron and Lake Erie of the Laurentian Great Lakes. The river once supported a substantial lake whitefish (Coregonus clupeaformis) fishery until the early 1900s, when habitat loss, pollution, and overfishing contributed to the collapse of the fishery and loss of spawning populations in the river....

Ben Augustine, J. Andrew Royle
2024, Preprint
The U.S. Fish and Wildlife Service monitors species-specific waterfowl (ducks, seaducks, geese, and brant) harvest through two hunter surveys, one that estimates the total harvest for each waterfowl group, and a second that estimates the species composition of each waterfowl group. Point estimates for species-specific harvest can be computed by...

Roger Pieters, Gregory A. Lawrence, Albert Leung, John Crusius, Thomas Pedersen
2024, Limnology and Oceanography (69) 1905-1917
We detail the effect of a small stream of dense inflow that significantly altered the stratification and water quality in a constructed water body in northern British Columbia, Canada. As the dense inflow passed through the epilimnion of the steep-sided lake, it entrained relatively large quantities of water. The resulting...

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...

Joseph R. Benjamin, Jason Dunham, Nicholas Scheidt, Carla Rothenbuecher, Cory Sipher
2024, River Research and Applications (40) 2009-2021
Assisted migration is a means of introducing a species into a previously unoccupied area. Although this idea is relatively new for many species, there are many extant examples involving fish that can be instructive. We studied a case of assisted migration where upstream access of migrating adult coho salmon Oncorhynchus kisutch over...
