Data

This data release presents data that were collected as part of a larger effort to refine knowledge pertaining to the origin, composition, and seasonality of dissolved organic matter in lakes. This work was part of an international collaborative effort with the Global Lake Ecological Observatory Network (GLEON). Water samples were collected monthly during 2021 and shipped to GLEON for determination

We compiled electrofishing and habitat data sampled from 1990 to 2019 in the Harney Basin by the US Geological Survey (USGS), Oregon Department of Fish and Wildlife (ODFW) and the High Desert Partnership (HDP) to describe native and non-native fish distributions and their habitat associations. USGS collected eDNA data in 2019 to refine the known distributions of common carp (Cyprinus carpio). Site

Yuma Ridgway's rail (Rallus obsoletus yumanensis, hereafter, "rail" are an endangered species for which patches of emergent marsh within the Salton Sea watershed comprise a substantial portion of habitat for the species' disjointed range in the southwestern United States. These areas of emergent marsh include: 1) marshes managed by federal (particularly the U.S. Fish and Wildlife Service's Sonny B

Prior to the initiation of translocation efforts in 2017, Pacific lamprey (Entosphenus tridentatus) were last documented in the Okanogan river subbasin in 2010. It appears as if lamprey were extirpated in the Okanogan subbasin some time shortly after that. However, until 2017, monitoring and management actions for lamprey were minimal in the Okanogan subbasin. This lack of monitoring has resulted

The U.S. Geological Survey (USGS) Remote Sensing Coastal Change (RSCC) project collects aerial imagery along coastal swaths, in response to storm events, with optimized endlap/sidelap and precise position information to create high-resolution orthomosaics, three-dimensional (3D) point clouds, and digital elevation/surface models (DEMs/DSMs) using Structure-from-Motion (SfM) photogrammetry methods.

This U.S. Geological Survey (USGS) data release provides phytoplankton data collected from Stagecoach Reservoir, Colorado, during the summer months, July through September, of 2017 and 2018. The data were collected by the USGS, in cooperation with the Upper Yampa Water Conservancy District and Colorado Parks and Wildlife. All data are reported as raw calculated values and are not rounded to USGS s

This data release documents the data used for the associated publication "Evaluating hydrologic region assignment techniques for ungaged watersheds in Alaska, USA" (Barnhart and others, 2022) The data sets within this release are stored in 14 files: (1) Streamflow observations and sites used. (2) Statistically estimated streamflow values computed for each site. (3) Streamflow statistics computed f

Images were collected using a remotely piloted unoccupied aerial system over the bluffs of the eastern shore of Lake Michigan in Miami Park rural residential area, Allegan County, MI. Images were collected on July 19, 2021, by Richard Becker, University of Toledo, and cover an extent between south of Lakestone Dr. to the north, and south of A St. to the south. Images were collected to monitor acti

Observations of irrigated agricultural land within the Willcox Groundwater Basin in Arizona. Crops were verified in situ twice in 2020, first on May 20th and again on August 12th; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program images dated 2019 and supplemented with Landsat and Sentinel2 imagery collec

Oklahoma State University South-Central Research Station (SCRS) was used to conduct research to understand the chemical composition of various water types and their potential environmental and human health effects. The study area provided the opportunity to study five water types: (1) receiving surface water (Washita River), (2) urban stormwater, (3) wastewater treatment plant effluent used for ir

The data set contains location, depth, and geologic data from drill holes penetrating the Paleocene Fort Union Formation in the Williston Basin in McLean County in west-central North Dakota.
