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.

Caernarvon Freshwater Diversion (BS-0008): 1998 land-water classification
The Louisiana Coastal Protection and Restoration Authority 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 to arresting coastal wetlands loss. This data set includes mo
Davis Pond Freshwater Diversion (BA-0001): 1998 pre-construction land-water classification of the BA-0001 Ponding Area
The Louisiana Coastal Protection and Restoration Authority 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 to arresting coastal wetlands loss. This data set includes mo
Passive integrated transponder tag data from the West Brook, MA, USA
The Ecology Section at the USGS Conte Laboratory has studied fish in the West Brook since 1997. The goal is to understand the strength and direction of drivers on fish growth, movement, reproduction and survival in the wild. We hope to provide a comprehensive understanding of fish population dynamics for this stream network and ultimately individual fitness (natural selection and evolution) in the
Juvenile coho salmon growth differences track biennial pink salmon spawning patterns
Spawning salmon provide marine derived resources to freshwater ecosystems that can benefit stream-dwelling fish foraging and growth. Pink salmon are widely distributed throughout watersheds along the north pacific ocean, and display distinct biennial fluctuations in spawning abundance. These data were collected from a coastal watershed in northern southeast Alaska (Montana Creek) to explore the hy
Data from two bathymetric surveys of the Sandusky River near Bradys Island, Fremont, Ohio, March 2023 and May 2024.
As part of the Great Lakes Restoration Initiative (GLRI) project template 774-GC10 entitled, “Characterization of hydrology and sediment mobility to inform design and implementation of a seasonal barrier to disrupt invasive grass carp reproduction in the Sandusky River near Brady’s Island, Ohio”, two bathymetric surveys of the Sandusky River from the Hayes Avenue bridge to the Ohio State Route 6 b
Pesticide concentrations in water samples and quality-control samples collected at surface-water sites in Hawaiʻi, 2016–19
This dataset contains pesticide-concentration values and other information for water samples and quality-control samples collected at surface-water sites on the Hawaiian Islands of Kauaʻi, Oʻahu, Maui, and Hawaiʻi between November 2016 and June 2019. The water water samples and quality-control samples were collected for a study that assessed pesticides in surface water in Hawaiʻi, as described in
Pesticide, organic-contaminant, and wastewater-indicator results for passive samplers deployed in surface water and groundwater in Hawaiʻi, 2015–19
The U.S. Geological Survey (USGS) deployed passive samplers at surface-water and groundwater sites on the Hawaiian Islands of Kauaʻi, Oʻahu, Maui, and Hawaiʻi for several weeks each during 2015–19. The passive samplers were deployed to assess the occurrence of pesticides and pesticide degradates, herein referred to as pesticides, in water at the sites. Some of the passive samplers were also used t
Surface-water sites in Hawaiʻi where pesticides were assessed, 2015–19
This dataset includes information for the sample sites in Hawaiʻi where pesticides in surface water were assessed during 2015–19. The sample sites were distributed on the Hawaiian Islands of Kauaʻi, Oʻahu, Maui, and Hawaiʻi. The site information is provided in two formats: a comma-separated-value (CSV) file and a shapefile formatted for use in a geospatial information system. A summary of the pest
Cropland Data Layer summaries for NHDPlus Version 2.1 Reach Catchments in the Conterminous United States, 2000-2022
This dataset contains summary tables of land cover from the Cropland Data Layer (CDL) for individual stream catchments of the conterminous United States from the National Hydrography Dataset Plus Version 2.1 (United States Department of Agriculture National Agricultural Statistics Service, 2024; McKay and others, 2012). These data were summarized from primarily 30 meter grid cell raster data for t
Capture records of Desmognathus salamanders in Shenandoah National Park, 2007-2013
Mark-recapture records of salamanders in the genus Desmognathus within stream habitat at Shenandoah National Park, Virginia from 2007-2013
Illinois River basin silver carp and bighead carp eDNA gradient study from 2015
This data was collected by the US Fish and Wildlife Service to see if environmental DNA (eDNA) varied across pools and within pools in the Illinois River basin. The data was collected in 2015 from three different habitat types: shoreline, main channel, and bays. The resulting data were then analyzed using an occupancy model.
Hyperspectral image transects and field measurements of reflectance, visible dye concentration, and flow velocity acquired during a tracer experiment on the Missouri River near Lexington, MO, on May 11, 2024
This data release includes several types of remotely sensed data and field measurements acquired during a tracer experiment performed on the Missouri River near Lexington, Missouri, on May 11, 2024. One of the primary goals of this study was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) in a large, highly turbid natural river channel using data from a Uncrew
