Stormwater Control Measures (SCM) Monitoring, Griggs Reservoir In Columbus

Increased stormwater runoff and associated problems, including increased pollution and flooding, have led to engineered attempts to return urban areas to a more natural water cycle. The USGS, in cooperation with the Franklin Soil and Water Conservation District and the City of Columbus, is collecting hydrologic data to determine the effectiveness of recently installed rain gardens near Griggs...

Crest-Stage Streamgage Network In Ohio

Historically, streams with drainage areas less than 100 square miles have not been adequately represented in regional peak flow analysis. To help fill this data gap, crest-stage gages were installed in 2001 at 18 sites throughout Ohio in order to augment the peak flow record for small streams (less than 100 square miles). After enough peak flow data have been collected at these sites, an...

Lake Erie (LERI) NAWQA Surface Water Status And Trends

The Lake Erie and Lake Saint Clair (LERI) Basins in Indiana, Michigan, New York, Ohio, and Pennsylvania comprise one of more than 50 study units that are part of the USGS National Water Quality Assessment (NAWQA) Program. The long-term goals of the NAWQA program are to describe the water-quality status and trends in a large representative part of the Nation's surface-water and groundwater...

Monitoring Of Groundwater Levels And Surface-Water Quality At The South Well Field, Franklin County, Ohio

The City of Columbus operates 5 high-capacity collector wells to extract groundwater for drinking-water supply. To assist the City, the USGS monitors water levels in 5 observation wells and operates a water-quality monitor on the Scioto River where specific conductance, temperature, dissolved oxygen, pH, and turbidity are measured on an hourly basis. In addition, groundwater-level synoptic...

Long-term Water-level Monitoring Network, Geauga County, Ohio

Residents of Geauga County rely almost exclusively on groundwater as their source of drinking water. County planners are concerned that steady population growth and associated increased withdrawals of groundwater may cause a decline in groundwater levels. Declining groundwater levels indicate a decrease in the amount of groundwater that is available for human use and to maintain streamflow...

NAWQA - Regional Stream-Quality Assessment Field Data Management

The Regional Stream-Quality Assessment (RSQA) of the National Water-Quality Assessment Program (NAWQA) assesses the ecological stressors in various regions across the United States. The stressors are related to water quality, streamflow, and toxicity. Field data management ensures a clean, complete dataset for interpretation and analysis with no loss of samples or data.

Nowcast - Water-Quality Conditions At Beaches And A Recreational River

Local agencies monitor water to measure the concentration of Escherichia coli (E. coli)—an indicator bacterium found in sewage and other animal wastes—to determine whether the water is safe for contact recreation such as swimming or canoeing. Conventional analytical methods can take 18 to 24 hours to yield results. To improve the timeliness and accuracy of recreational water-quality...

Modeling Aquatic Species Distributions On The Basis Of Physical Habitat

Gap analysis is a coarse-scale assessment of aquatic biodiversity and conservation, the results of which can be used to guide biological field studies and monitoring programs. Potential species distribution models were developed for 130 fish, 70 bivalve, and 17 native crayfish species on the basis of a physical habitat-based classification of the perennial streams in Ohio.

Response of Migrating Birds to Hurricane Sandy

The Challenge: Each autumn, millions of landbirds migrate southward from breeding areas in the U.S. and Canada. Because these migrations occur during hurricane season, the impacts of hurricanes on migrating birds and their en route resting and foraging sites (stopover sites) are a real concern. Hurricane Sandy occurred late in the landbird migration season. By the time the storm made landfall...

Nocturnal Bird Migration through the Central Appalachians

The Challenge: Concerns have arisen about the potential impacts of wind power development in the Appalachians on migrating birds, creating a critical need for information on their distribution and flight characteristics as they pass through the region. This study focuses on the spatial and temporal distribution of nocturnally migrating birds in the Central Appalachians (MD, VA, WV). The...

Radar Analysis of Fall Migration Stopover Sites in the Northeastern U.S.

The Challenge: Most landbird conservation efforts focus on protecting or enhancing breeding habitat. For migratory species, however, mortality is highest during the biannual migration periods. In fall, juvenile birds are making their first migratory flights; their success, and that of adult birds, depends on availability of suitable sites to safely rest and forage. Identifying important...

Sediment toxicity and status of benthic macroinvertebrate communities in the remediated Buffalo River Area-of-Concern

Background : Contaminated bed sediments in much of the Buffalo River AOC (Figure 1A, 1B) were removed (dredged) between 2011 and 2015. Plans to monitor and assess the effectiveness of this management action on 8 of 9 beneficial-use-impairments (BUI), included the benthic macroinvertebrate (benthos) BUI, were revised by the Buffalo Niagara Riverkeeper (Riverkeeper, 2014). Funds needed to...

Sediment infilling benefits rainbow trout passage in a baffled channel

Fish are thought to exploit low velocity recirculation zones in the wakes of baffles to take refuge from challenging hydraulic conditions in baffled culverts. Here, we investigate how sediment deposition in the wakes of baffles affects passage and behaviors of juvenile rainbow trout in a baffled experimental flume. High...

Endangered species recovery: A resource allocation problem

Many nations have laws to identify and protect imperiled species and their ecosystems. In the United States, actions taken under the Endangered Species Act (ESA) have prevented many extinctions, but few listed species have recovered to the point where they can have the ESA protections removed (1, 2). One reason for this [among many (3)] is a...

Investigating home range, movement pattern, and habitat selection of Bar-headed Geese during breeding season at Qinghai Lake, China

The Bar-headed Goose is an important species in Asia, both culturally and ecologically. While prior studies have shown Qinghai Lake supports one of the largest breeding areas for Bar-headed Geese, little is known regarding the species movement ecology during the breeding season. In this study, we examined Bar-headed Goose home range size within...

Dynamics of gene expression responses for ion transport proteins and aquaporins in the gill of a Euryhaline Pupfish during freshwater and high salinity acclimation

Pupfishes (genus Cyprinodon) evolved some of the broadest salinity tolerances of teleost fishes, with some taxa surviving in conditions from freshwater to nearly 160 ppt. In this study, we examined transcriptional dynamics of ion transporters and aquaporins in the gill of the desert Amargosa pupfish (Cyprinodon nevadensis amargosae) during...
