This dataset describes the hydrogeomorphic structure and lake-tributary mixing in three intermediate-sized Lake Michigan rivermouths: Ford River, Manitowoc River, and Pere Marquette River. Data were collected from May to October 2011. Water chemistry variables were measured with a multiparameter sonde along longitudinal, lateral, and vertical transects. Magnesium, boron, and stable water isotope concentrations were also determined from grab water samples at particular depths.
The U.S. Geological Survey (USGS), in cooperation with the Puerto Rico Environmental Quality Board, has compiled a series of geospatial datasets for Puerto Rico to be implemented into the USGS StreamStats application (https://streamstats.usgs.gov/ss/). These geospatial datasets, along with basin characteristics datasets for Puerto Rico published as a separate USGS data release (https://doi.org/10.5066/P9HK9SSQ), were used to delineate watersheds and develop the peak-flow and low-flow regression equations used by StreamStats. The geospatial dataset described herein are the sink watershed grid rasters at a 10-m resolution. A value is assigned to pixels in each sink watershed and the count of cells that drain to that...

The U.S. Geological Survey (USGS), in cooperation with the Federal Emergency Management Agency, Pennsylvania Department of Environmental Protection, Pennsylvania Department of Transportation, and Susquehanna River Basin Commission, prepared hydro-conditioned geographic information systems (GIS) layers for use in the Pennsylvania StreamStats application. These data were used to update the peak flow and low flow regression equations for Pennsylvania. This dataset consists of flow direction rasters for each 8-digit Hydrologic Unit Code (HUC) area in Pennsylvania, one of the layer types needed to delineate watersheds within the HUC-8 areas, merged into a single dataset. The 59 HUCs represented by this dataset are 02040101,...

Malheur Lake is a shallow, freshwater lake in southeastern Oregon. This data release includes phytoplankton data from three sites located in Malheur Lake collected from 8/8/2018 to 8/11/2020. For each sample collected, the phytoplankton were reported to the lowest taxonomic unit. Phytoplankton biovolume, algal cell concentration, and algal biomass concentration are included. All phytoplankton data were generated by PhycoTech, Inc. The dataset includes two comma-separated values (.csv) files and metadata. The first CSV file includes all of the taxonomic, biovolume, and density information. The second CSV file includes the 111 unique taxa identified.

Methylmercury (MeHg) and total mercury (HgT) stable isotope measurements were made by the USGS Mercury Research Lab (MRL) in different organs on the Giant Petrels (Macronectes spp.) to examine internal mercury cycling in these seabirds. These data were collected as a compliment to x-ray spectroscopy measurements made by the University of Grenoble, France. The tissues and feathers of the southern giant petrels exhibit large variability in mercury-202 isotope values (δ202HgT), which are typically used to ascertain Hg sources in the environment. These values follow a pattern across all individuals based on tissue type: feathers (δ202HgT = 2.74 ± 0.16‰, n =5, mean ± standard deviation) > brain (δ202HgT = 1.09 ± 0.77‰,...

In response to the 2010 Fourmile Canyon fire near Boulder, Colorado, the U.S. Geological Survey collected data to support investigations into the magnitude and critical drivers of water-quality impairment after wildfire. We analyzed chemistry of stream water, sediment, wildfire ash, soil, dust, and mine waste for metals and other parameters in order to evaluate the effects of legacy mining and wildfire on stream chemistry in the Colorado Front Range, USA. This data release includes data that were published earlier (McCleskey et al., 2012; Murphy et al., 2018).
This dataset contains U.S. Geological Survey (USGS) developed hydrology data at nine dam removal and culvert retrofit sites in the northeastern United States (Olson and Simeone, 2021). Hydrology was estimated for the river reaches of the hydraulic models. The hydrology estimated generally included flood flows for the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probability, and mean monthly streamflows. The hydrology data are used to support the development of one-dimensional and two-dimensional U.S. Army Corps of Engineer (USACE) Hydrologic Engineering Center’s River Analysis System (HEC-RAS) models for both the pre- and post-dam removal and culvert-retrofit conditions. The referenced models...

Particle-size data collected of the upper 25 cm of substrate was collected at 12 sites in October 2018 and May 2019 at Olsen's Beach in Lake Ozette, Clallam County, Washington. At emergent stations, the top 25 cm of substrate was collected using a shovel and was transferred into a bucket. Bulk sediment samples were collected at submergent stations using a McNeil sampler inserted into the lakebed (McNeil and Ahnell, 1964) from which sediment was extracted by hand to a depth of 25 cm below the lakebed and residual water containing suspended sediment was sampled. Particle size distribution of sediment larger than 8 mm was sieved and weighed in the field and sediment less than 8 mm was sent to the USGS Cascades Volcano...

Real-time, high frequency (1-second sample interval), georeferenced water quality data was collected in Utah Lake, Utah. Utah Lake is located approximately 45 miles south of Salt Lake City, Utah, and approximately 5 miles west of Provo, Utah. Data was collected on 8/10/16 over an approximate 6.5-hour period (8:00 – 14:30 h PST) while underway. Sample water was continuously pumped through a pickup tube mounted at the stern of the vessel. Sample was pre-filtered using a 178 um in-line strainer, passed through a de-bubbler, and diverted through a 0.2 micron filter to various water quality instrumentation. Data was handled by a Campbell Scientific CR-6 data logger and recorded continuously to a Microsoft Excel file....
