Stakeholder Engagement for Water-Hazard Science and Response in the USGS Rocky Mountain Region Stakeholder Engagement for Water-Hazard Science and Response in the USGS Rocky Mountain Region
Stakeholder engagement is essential to successful development and implementation of products and services supporting emergency management. Governmental agencies often have a unique challenge of ensuring equitable stakeholder representation across large geographic, administrative, and topical areas. This project used stakeholder engagement to understand end-users needs concerning water...
Phytoplankton Species Composition and Abundance in the Sacramento-San Joaquin River Delta: Microscopic Enumeration of USGS Samples, beginning in 2016 (ver. 2.0, December 2025) Phytoplankton Species Composition and Abundance in the Sacramento-San Joaquin River Delta: Microscopic Enumeration of USGS Samples, beginning in 2016 (ver. 2.0, December 2025)
This dataset contains multiple types of data characterizing phytoplankton in the Sacramento-San Joaquin Delta (California, USA). 1) Bright field microscopy was used to identify and enumerate phytoplankton community composition; 2) Epifluorescent microscopy was used to enumerate picophytoplankton (phytoplankton cells less than 2 microns in diameter) and, 3) a categorical visual index...
Phytoplankton, algal toxin, and water-quality data for Blue Mesa Reservoir, Colorado, 1970–2023 Phytoplankton, algal toxin, and water-quality data for Blue Mesa Reservoir, Colorado, 1970–2023
Blue Mesa Reservoir (Blue Mesa) is the largest storage reservoir in Colorado and is used for water supply and recreation. The reservoir consists of three distinct basins which are, moving from east to west, Iola, Cebolla, and Sapinero. This data release includes a wide variety of data collected to understand conditions that contribute to algal blooms in Blue Mesa. Data include...
Predictive layers of trace elements in soil in the conterminous United States Predictive layers of trace elements in soil in the conterminous United States
This dataset provides posterior mean predicted rasters of the distribution of trace elements important to vertebrate health (cobalt, copper, iron, manganese, selenium, and zinc) in the soil across the conterminous United States. Rasters were generated using a Bayesian modeling framework implemented in R with the R-INLA framework (Integrated Nested Laplace Approximation) and the...
Six Fathom Bank and Yankee Reef Gillnet and Beam Trawl Data 1991-2022 Six Fathom Bank and Yankee Reef Gillnet and Beam Trawl Data 1991-2022
Annual spring/summer (May-July) and fall (October) gillnet assessment surveys and spring/summer young-of-year (YOY) lake trout beam trawl surveys were conducted by researchers at the USGS Great Lakes Science Center (GLSC) in central Lake Huron on two offshore reefs, Six Fathom Bank and Yankee Reef. The spring/summer and fall gillnet assessment took place between 1991- 2022 and 1991-1998
Wyoming Range fish data 2012-2019 Wyoming Range fish data 2012-2019
The goal of the study associated with this dataset was to characterize flow-ecology relationships for Mottled Sculpin (Cottus bairdii) and Mountain Sucker (Catostomus platyrhynchus) in snowpack driven headwater streams of the Upper Green River Basin in Wyoming, U.S.A. Our objectives were to: 1) evaluate whether variation in Mottled Sculpin and Mountain Sucker abundance is driven by...
