Lake Michigan juvenile lake trout diets 2015-2017, 2019-2022

These data consist of juvenile lake trout biological and diet information collected from USGS bottom trawl, beam trawl, and gillnet surveys in Lake Michigan from 2015-2017 and 2019-2022. All prey were identified, enumerated and weighed. Only fish prey and Mysis had lengths measured.

Bibliography of hydrological and ecological research in the Great Basin terminal lakes, USA

This database contains literature citations and associated abstracts pertaining to the ecology and hydrology of terminal lakes in the Great Basin region of the western United States. This is not meant to be an exhaustive list, nor did we perform a systematic meta-analysis; rather, literature records were included based on topical relevance.

Length, Weight, Energy Density, and Isotopic Values of Fish from Rivers in Northwest Alaska, 2015-2019

This dataset contains length, weight, energy density, and isotope values of fish collected in northwest Alaskan rivers during summer and fall 2015-2019.

Engineering Soil Classification and Geotechnical Measurements in Lares, Naranjito, and Utuado, Puerto Rico

The data includes soil texture, soil-water, and estimated soil strength properties for soil map units and from geotechnical investigations of landslide areas affecting highways in the municipalities of Lares, Naranjito, and Utuado, Puerto Rico.

Model input and output data covering Lares Municipio, Utuado Municipio, and Naranjito Municipio, Puerto Rico, for landslide initiation susceptibility assessment after Hurricane Maria

Hurricane Maria induced about 70,000 landslides throughout Puerto Rico, USA (Hughes and others, 2019). Data in this project pertain to two areas situated in Puerto Rico’s rugged Cordillera Central range. Combined, these areas account for more than half of the hurricane-induced landslides. One of these areas encloses two neighboring municipalities, Lares Municipio, and Utuado Municipio, and the sec

Data for Estimating Peak-Flow Quantiles for Selected Annual Exceedance Probabilities in Illinois

The U.S. Geological Survey Central Midwest Water Science Center completed a report (Over and others, 2023) documenting the methods, results, and applications of an updated flood-frequency study for the State of Illinois. This data release contains data related to the analysis completed to determine peak-flow quantiles (flood frequency estimates) at streamgages in Illinois for 50-, 20-, 10-, 4-, 2-

Data Release: Buttonland Swamp, SET data

This study examined long-term changes in ground height using Surface Elevation Tables (SETs). Measurements were taken in the floodplains of the Cache River at Buttonland Swamp in southern Illinois. The sites where data was collected included Crawford Tract and Eagle Pond from 2020-2022 and Deer Pond and Snake Hole from 2005-2022.

Data Release: Buttonland Swamp, water data, 2021

A Solinist water logger was used to collect water data at the Crawford Tract section of the Cache River Watershed in Illinois from June 22nd to November 29th of 2021. This data included temperature, pressure, and depth.

Multispectral images and field measurements of water depth from the Sacramento River near Glenn, California, acquired September 14-16, 2021

This data release includes multispectral images and field measurements of water depth from the Sacramento River near Glenn, California, used to evaluate the potential for efficient reach-scale mapping of river bathymetry using Uncrewed Aircraft Systems (UAS). The images were acquired by a MicaSense RedEdge-MX Dual Camera deployed from a Trinity F90 vertical take-off and landing (VTOL) UAS. The 4 k

Groundwater potentiometric-surface contours and well numbers used to map groundwater potentiometric-surface altitude in 2022 and groundwater-level changes between 1968, 1991, and 2022 in the alluvial aquifer in the Big Lost River Valley, south-central Ida

Groundwater potentiometric-surface contours for spring 2022 (April 4 to 8, 2022) and autumn 2022 (October 30 to November 4, 2022) were created for the alluvial aquifer in Big Lost River Valley. The well numbers and station names used to create the potentiometric-surface contours and groundwater-level change maps are provided in this data release. The location, depth to water, and potentiometric-su

U.S. Geological Survey 2021 Data Management Planning Survey Results and Analyses

In 2021, the U.S. Geological Survey's (USGS) Science Data Management Team distributed four surveys related to Data Management Plans (DMPs) and Data Management Planning to USGS researchers, data managers and information technologists, Center Directors, and Program Coordinators and Bureau Approving Officials. This data release includes survey results with redactions (to allow survey participants to

Simulating changes in the distribution of ammonium and ammonia versus physical and chemical conditions using PHREEQC with applications to toxicity to fish

Two sets of PHREEQC input and output files are provided that illustrate the distribution of aqueous ammonium and ammonia as a function of physical (temperature) and chemical (pH and solution composition) conditions. One set of simulations calculates the distribution of aqueous ammonia and aqueous ammonium over a range of temperatures and pH values in different solution compositions. The other set
