Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Efficacy of carbon dioxide for preventing quagga veliger settlement in a raw water system on the Colorado River, AZ Efficacy of carbon dioxide for preventing quagga veliger settlement in a raw water system on the Colorado River, AZ
We evaluated the efficacy of carbon dioxide (CO2) for preventing settlement of the biofouling quagga mussel (Dreissena bugensis) in raw water systems. Trials were conducted in a mobile laboratory located at the US Bureau of Reclamation, Davis Dam Hydropower Facility, and supplied with raw water from the Colorado River. Incoming water was split between five chambers where CO2 was...
Data Release for Using Environmental DNA to Effectively Detect Aquatic Arthropods: Monitoring Seasonal Changes in eDNA Concentration Data Release for Using Environmental DNA to Effectively Detect Aquatic Arthropods: Monitoring Seasonal Changes in eDNA Concentration
Detection of environmental DNA (eDNA) has become a commonly used surveillance method for threatened or invasive vertebrates in both aquatic and terrestrial environments. However, use of eDNA methodologies for the detection of aquatic invertebrates (e.g., crayfish and insects) has been limited. Environmental DNA protocols can be especially useful for endangered invertebrates such as the...
Data release for a novel tool to selectively deliver a control agent to filter-feeding silver and bighead carp Data release for a novel tool to selectively deliver a control agent to filter-feeding silver and bighead carp
Invasive carp pose substantial economic and ecological damage when populations are widespread in freshwater systems within the United States of America (USA). Resource managers in the USA have a limited number of chemical control tools to selectively remove nuisance fish. The present study examined whether Antimycin-A (antimycin) wax encapsulated microparticles could cause selective...
Milwaukee Metropolitan Sewerage District nutrient connections project—In-stream nutrient cycling, 2022 data Milwaukee Metropolitan Sewerage District nutrient connections project—In-stream nutrient cycling, 2022 data
Understanding sediment nutrient dynamics in the Milwaukee River Basin is important for assessing water quality and stream habitat. The Milwaukee River is a major tributary to Lake Michigan that provides clean drinking water for over one million people. Urban and agricultural runoff are linked to elevated loads of phosphorus, nitrogen, and sediment in the river. Excessive nutrients can...
Global Aggregation of Stream Silica (GlASS) (ver. 2.0, July 2025) Global Aggregation of Stream Silica (GlASS) (ver. 2.0, July 2025)
Riverine silicon (Si) plays a vital role in governing primary production, water quality, and carbon sequestration. The Global Aggregation of Stream Silica (GlASS) database was constructed to assess changes in riverine Si concentrations and fluxes, their relationship to available nutrients, and to evaluate mechanisms driving these patterns. GlASS includes dissolved Si (DSi), dissolved...
