Carbon dioxide (CO2) is under consideration as a chemical fish deterrent at pinch points in rivers (e.g., inside locks) to reduce unwanted fish passage. This study evaluated the behavioral responses of invasive round goby (Neogobius melanostomus) to dissolved CO2 in laboratory tanks. The goal of this project was to quantify CO2 concentrations that modify round goby behavior. More specifically, avoidance behavior (voluntary response) and loss of equilibrium (involuntary response) were quantified across 5, 15, and 25°C water temperatures. These data can be used to inform future field testing of CO2 as an invasive fish deterrent. Spreadsheets include data that were used to evaluate the efficacy of carbon dioxide (CO2)...
Interest in the field of environmental DNA (eDNA) is growing rapidly and eDNA surveys are becoming an important consideration for aquatic resource managers dealing with invasive species. However, in order for eDNA monitoring to mature as a research and management tool, there are several critical knowledge gaps that must be filled. One such gap is the fate of eDNA materials in the aquatic environment. Understanding the environmental factors that influence the decay of eDNA and how these factors impact detection probabilities over time and space could have significant implications for eDNA survey design and data interpretation. Here we experimentally explore eDNA decay in waste materials and reproductive cells obtained...

This dataset includes stream temperatures from two data loggers installed at one site in the Little Blitzen River of SE Oregon as part of a redband trout (Oncorhynchus mykiss gairdnerii) study. The site was used as an undisturbed reference in comparison with similar temperature monitoring sites in the Willow-Whitehorse watershed that experienced a 2012 fire that burned nearly the entire watershed.
Changes in the Earth’s climate are expected to impact freshwater habitats around the world by altering water temperatures, water levels, and streamflow. These changes will have consequences for inland fish – those found within lakes, rivers, streams, canals, reservoirs, and other landlocked waters – which are important for food, commerce, and recreation around the world. According to the U.S. Fish and Wildlife Service, in 2011, 33.1 million people fished and spent $41.8 billion in the United States alone. Yet to date, little comprehensive research has been conducted to investigate the effects of climate change on inland fisheries at a large scale. The aim of this project was to summarize the current state of knowledge,...

Floods, spatially complex water flows, and organism movements all generate important fluxes of aquatic-derived materials into terrestrial habitats, counteracting the gravity-driven downhill transport of matter from terrestrial-to-aquatic ecosystems. The magnitude of these aquatic subsidies isoften smaller than terrestrial subsidies to aquatic ecosystems but higher in nutritional quality, energy density, and nutrient concentration. The lateral extent of biological aquatic subsidies is typically small, extending only a few meters into riparian habitat; however, terrestrial consumers often aggregate on shorelines to capitalize on these high-quality resources. Although the ecological effects of aquatic subsidies remain...

How local geomorphic and hydrologic features mediate the sensitivity of stream thermal regimes to variation in climatic conditions remains a critical uncertainty in understanding aquatic ecosystem responses to climate change. We used stable isotopes of hydrogen and oxygen to estimate contributions of snow and rainfall to 80 boreal streams and show that differences in snow contribution are controlled by watershed topography. Time series analysis of stream thermal regimes revealed that streams in rain-dominated, low-elevation watersheds were 5–8 times more sensitive to variation in summer air temperature compared to streams draining steeper topography whose flows were dominated by snowmelt. This effect was more pronounced...

Navajo Reservoir on the San Juan River serves as a water storage, flood control and power generation project for the San Juan River Basin. Because of deep hypolimnetic release from the dam, water temperatures are cooler than natural pre-dam conditions. Post-dam release water temperatures during the summer months are 4-8 �C (39-46 �F) as compared to pre-dam temperatures of 20-25 �C (68-77 �F). Colder water temperatures from the dam to Shiprock (~80 mile; 129 km downstream of the dam) may negatively impact survival of native fish species living below the dam but benefit the tail-water trout fishery (Vanicek, 1967; Holden, 1973; USBR, 2003). Colorado pikeminnow and razorback sucker are endangered fish species native...

It is well recognized that the climate is warming in response to anthropogenic emission of greenhouse gases. Over the last decade, this has had a warming effect on lakes. Water clarity is also known to effect water temperature in lakes. What is unclear is how a warming climate might interact with changes in water clarity in lakes. As part of a project at the USGS Office of Water Information, several water clarity scenarios were simulated for lakes in Wisconsin to examine how changing water clarity interacts with climate change to affect lake temperatures at a broad scale. This data set contains the following parameters: year, WBIC, durStrat, max_schmidt_stability, mean_schmidt_stability_JAS, mean_schmidt_stability_July,...

This database contains hourly water and air temperature data from 120 site locations within 17 watersheds in Shenandoah National Park, Virginia between June 23,2012 and October 25, 2016. The database includes three separate table files (i.e, entities) in csv format: 1) Water temperature data, 2) air temperature data, and 3) site location data. All temperature data were collected using HOBO Pro V2 thermographs (accuracy = 0.2 degrees Celsius, drift = <0.1 degrees Celsius per year per year). These raw data were summarized to mean daily air and water temperatures for the analysis used in Johnson et al. Johnson, Z.C., Snyder, C.D. and Hitt, N.P., 2017, Landform features and seasonal precipitation predict shallow groundwater...

In this first worldwide synthesis of in situ and satellite-derived lake data, we find that lakesummer surface water temperatures rose rapidly (global mean = 0.34°C decade1) between 1985 and2009. Our analyses show that surface water warming rates are dependent on combinations of climate andlocal characteristics, rather than just lake location, leading to the counterintuitive result that regionalconsistency in lake warming is the exception, rather than the rule. The most rapidly warming lakes are widelygeographically distributed, and their warming is associated with interactions among different climatic factors—from seasonally ice-covered lakes in areas where temperature and solar radiation are increasing whilecloud...

High frequency water-quality measurements were collected by the U.S. Geological Survey within Willow Creek Reservoir located in Heppner, Oregon. All measurements were taken at 1.5 feet below the surface with a YSI EXO2 multiparameter sonde. Information collected include location, time, water temperature, pH, specific conductance, dissolved oxygen, total chlorophyll, blue-green algae phycocyanin, and turbidity. The measurements were collected while boating around the reservoir at about 2.5 miles per hour.

Data were collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center to investigate the influence of wind waves on sediment dynamics in two flooded agricultural tracts in the northern Sacramento-San Joaquin Delta: Little Holland Tract and Liberty Island. This effort is part of a large interdisciplinary study led by the USGS California Water Science Center and funded by the U.S. Bureau of Reclamation to investigate how shallow-water habitats in the Sacramento-San Joaquin Delta function and whether they provide good habitat for native fish species, including the Delta smelt. Elevated turbidity is a requirement for Delta smelt habitat, and turbidity is largely comprised of suspended sediment....

Water temperature and the availability of cold-water refugia are important parameters during summer baseflows when stream water temperatures are at their maximum. The U.S. Geological Survey measured near-streambed and surface water temperatures along the lower Quinault River, on the Olympic Peninsula, Washington between August 9-12, 2016, during summer baseflow conditions. The survey occurred downstream from Lake Quinault from approximately River Kilometer (RK) 4 to approximately RK 49 (45 kilometers total). Near-streambed temperatures and water depths were measured at 1-second intervals, which occur on average at an approximately 1-meter water surface distance interval. Near-streambed temperature and depth were...
