Evaluation of alternative coatings for U.S. Geological Survey water-quality samplers
Each year, U.S. Geological Survey (USGS) personnel collect approximately 52,000 water-quality samples from rivers and streams across the United States. Several samplers are used by the USGS for water-quality sample collection in riverine environments. These samplers are coated with Plasti Dip to protect the exterior of the sampler; however, Plasti Dip is susceptible to fraying and wear...
RIce-Net: Integrating ground-based cameras and machine learning for automated river ice detection
River ice plays a critical role in controlling streamflow in cold regions. The U.S. Geological Survey (USGS) qualifies affected water-level measurements and inferred streamflow by ice conditions at a date later than the day of the actual measurements. This study introduces a novel computer vision-based framework, River Ice-Network (RIce-Net), that uses the USGS nationwide network of...
Spatiotemporal patterns in urban nutrient and suspended sediment loads and stream response to watershed management implementation
In recent years, local governments have invested heavily in management practices to reduce nutrient and sediment loads. These practices provide localities with nutrient and sediment regulatory reduction credits; however, their effects on water quality are poorly understood at the watershed scale. Long-term watershed-scale monitoring is essential for assessing progress toward water...

Informing Chesapeake Bay Watershed Management by Monitoring Trends in River Nutrient and Sediment Loads
The USGS has computed nutrient and suspended-sediment loads and trends through water year 2023 in Chesapeake Bay rivers. These monitoring-based estimates help federal, state, and local managers evaluate and plan water-quality restoration strategies.
Lake Accotink Sedimentation Study
Lake Accotink is a 55-acre lake in Fairfax County which is highly valued by the local community. Much like a living organism, lakes go through many changes. Several factors affect their health and well-being such as sediment buildup. As the lake fills with sediment, it loses surface area and volume. Lake Accotink has been dredged in the past to remove excess sediment, but this process is costly...
New study highlights the role of wastewater and landscape sources contributing to pesticide contamination in the Potomac River watershed
Wastewater treatment plant discharges can be a source of organic contaminants, including pesticides, to rivers. Pesticide concentrations were predicted based on wastewater percentages in stream water using a modeling tool, and verified with measured concentrations to identify other potential landscape sources.
