The data in this release were used to help evaluate and understand the distribution of fish and invertebrates as well as ecological response to streamflow, water temperature, and water chemistry within the Fountain Creek Basin. This data release consists of invertebrate data collected between 1985 and 2022, fish data collected between 2003 and 2022, as well as the data neccesary to recreate the tables and figures in the associated U.S. Geological Survey Scientific Investigations Report (http://dx.doi.org/10.3133/sirXXXXXXXX). See Zuellig and others (2022) for sampling methodology and site information.
Burnsville Cove in Bath and Highland Counties (Virginia, USA) is a karst region in the Valley and Ridge Province of the Appalachian Mountains. The region contains many caves in Silurian to Devonian limestone, and is well suited for examining geologic controls on cave location and cave passage morphology. In Burnsville Cove, many caves are located preferentially near the axes of synclines and anticlines. For example, Butler Cave is an elongate cave where the trunk channel follows the axis of Sinking Creek syncline and most of the side passages follow joints at right angles to the syncline axis. In contrast, the Water Sinks Subway Cave, Owl Cave, and Helictite Cave have abundant maze patterns, and are located near...

This dataset represents 505 campsites along the Colorado River in Grand Canyon with associated debris flow probabilities calculated for approximately a 100-year period (Griffiths and others, 2004) and geomorphic attributes mapped by the U.S. Geological Survey, Grand Canyon Monitoring and Research Center (USGS-GCMRC) (Hadley and others, 2018). The campsite polygons were developed as part of a master campsite database that was a collaborative effort to maintain between the National Park Service in Grand Canyon National Park and the USGS-GCMRC. Debris flow probabilities have been added as an attribute from ungauged tributary watersheds published in 2004 (Griffiths and others, 2004). Area and percentages of campsites...

Dreissenid management has focused primarily on chemical tools which are efficacious, but not without ecological or economic costs. There is a need for additional control tools that are less expensive, readily available, and will not leave a residue after treatment. Carbon dioxide has these advantages over chemical pesticides and has demonstrated effectiveness for control of a range of aquatic invasive species, including dreissenid mussels. Carbon dioxide was lethal to adult zebra mussels at levels that were safe to juvenile unionid mussels and lower levels cause detachment and gaping. Dreissenid veligers are more sensitive than adults to water quality conditions, including pH. Therefore, we hypothesized that effective...

This dataset provides cost estimates for 668 dam removal projects occurring in the United States. Cost estimates were obtained by searching the internet for sources of information that mention the cost of dam removal projects listed in the USGS Dam Removal Information Portal. When cost data were not available for a dam removal but contact information was, then personal communications were used to acquire additional cost information. The accuracy of estimates is not known but we assume that most estimates represent close to the total cost or the minimum financial cost, with overestimates being rare. Total cost information could include component costs related to project planning, dam deconstruction cost, and several...

As part of a large-scale study of nitrate contamination on Kirtland Air Force Base in central New Mexico, the USGS collected groundwater and surface water samples for artificial sweetener analyses. Samples were collected following standard USGS procedures (U.S. Geological Survey, variously dated), filtered to 0.45 microns, and frozen until analysis. Artificial sweeteners analyzed include neotame, acesulfame-K, aspartame, saccharin, and sucralose. Of the 49 sites sampled, 17 sites had measurable detections of artificial sweeteners. Neotame was the most commonly detected sweetener (n=12) followed by saccharin (n=5), acesulfame-K (n=2), aspartame (n=1), and sucralose (n=0). Concentrations ranged from 0.0003–0.011 μg/L...

This dataset represents 740 tributary canyons and/or watersheds adjacent to the Colorado River in Grand Canyon with associated debris flow probabilities from 2004. Also, these data include tributarys canyon and/or watersheds to Glen Canyon and several smaller watersheds in Grand Canyon where debris flow data is currently unavailable. Historic probabilities of debris flow occurrence were estimated by modeling the known frequency distribution with drainage basin parameters observed to control the process by which debris flows initiate and travel to the river. Observations from 1984 through 2003 provide a 20-year record of all debris flows that reached the Colorado River in Grand Canyon, and repeat photography provides...

Migratory species often provide ecosystem service benefits to people in one country while receiving habitat support in other countries. The multinational cooperation necessary to ensure continued provisioning of these benefits by migrational processes may be informed by understanding the benefits that people in different countries derive from migratory wildlife. We conducted stated preferences surveys to estimate the willingness of respondents from Canada, the U.S., and México to invest in conservation for two migratory species, the northern pintail duck (Anas acuta) and the Mexican free-tailed bat (Tadarida brasiliensis mexicana). These data include characteristics of were conservation payments might occur, of...

U.S. Geological Survey and partners are testing the effects of prescribed fire on Black Rails, Yellow Rails, and Mottled Ducks in the high marsh habitats of the northern Gulf of Mexico region. The study is conducted in cooperation with Mississippi State University, Illinois Natural History Survey, U.S. Fish and Wildlife Service, state agencies, universities, and non-governmental organizations. The objectives of this project are to develop an adaptive management framework that allows land managers to reduce our uncertainty about the effects of prescribed fire on these species and the habitats on which they depend, and give managers tools and information that will help them determine the best management actions to...

A hydro-economic model was developed by coupling a three-dimensional groundwater flow model of the Harney Basin, southeastern Oregon (using MODFLOW 6) with a hedonic agricultural economic model. The hydro-economic model was used to investigate a set of hypothetical future scenarios having different groundwater pumpage conditions. The model looked at conditions 30 years beyond the 2018 conditions at the end of the HBGM transient simulation. This USGS data release contains all of the input and output files and needed Python scripts and JuPyter Notebooks for the simulations described in the associated journal article (https://doi.org/10.1029/2024WRXXXX)

This dataset captures the Zebra Mussel dose-response to four independent toxicants and each binary mixture of those toxicants. Toxicants included EarthTec QZ, Clam-Trol CT-2 (syn. Spectrus CT1300), niclosamide, and potassium chloride. Each dose of toxicant was verified with either ICP-OES or UHPLC, depending on analyte, and comparison to a standard curve. Mortality was tabulated for each observation.

These are data associated with water column incubation experiments performed in the Fox rivermouth. The Fox River is a Lake Michigan tributary that enters Green Bay. These experiments are used to measure the transformation of inorganic and total dissolved nutrients occurring in the surface water of the rivermouth. Experiments had light and dark treatments, and some experiments were paired with experiments where nutrients were increased in initial spikes. Ancillary data associated with the experiments such as photosyntheticly active radiation (PAR) and chlorophyll a content are also included. In addition to the data, there is R code used to generate the uptake rates and perform the analyses described in the associated...

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts 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 mosaicked aerial photographs for the West Bay Sediment Diversion (MR-03) project for 2021. This data is used as a basemap land-water classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land loss within their project...

Seabeach amaranth (Amaranthus pumilus) is a plant species that was once prevalent on beaches of the U.S. mid-Atlantic coast but is now listed as threatened by the U.S. Fish and Wildlife Service. For much of the 20th century, seabeach amaranth was absent from the mid-Atlantic coast and thought to be extinct, presumably as a result of increased development and recreational pressure. One region where there has been an effort to restore the seabeach amaranth population is Assateague Island National Seashore (ASIS), a National Park Service land holding located along the coasts of Maryland and Virginia. Here, the Natural Resources staff at ASIS planted seabeach amaranth cultivars for three growing seasons from 1999...
