This dataset has been archived; it has been superceded by version 2.0 (September 2021) which can be found at https://doi.org/10.5066/P9RUUR4L Data from 10-day sediment toxicity tests of bed sediments from the Buffalo River Area of Concern (AOC) and reference reaches on the Buffalo River upstream of the AOC, Erie County, New York, respectively. Specifically, the data was used to compare the survival and growth of two macroinvertebrate species in sediments from study sites and laboratory controls. Results are from 10-day sediment exposures of two test species, Chironomus dilutus and Hyalella azteca. Sediment samples were collected from 8 sites within the AOC and from 6 reference sites upstream of the AOC. Bed-sediments...

The Colorado River is a crucial water source for millions of people in the Southwest. Warming temperatures, clearly documented in climate records for the Colorado River basin, are having an impact on the amount of annual streamflow yielded from rain and snow. Recent work has revealed that warming temperatures have played an increasingly important role over the past decades, both exacerbating droughts and dampening the effects of wet winters on high stream flows. Understanding and anticipating how warming temperatures will influence future water supply in the Colorado River basin is increasingly important for resource management, particularly in light of recent drought conditions. The overarching goals of this...

The U.S. Geological Survey (USGS) is collaborating with the New York Department of State (NYDOS) Office of Planning and Development to prepare a new Long Island South Shore Estuary Reserve (SSER) Coordinated Water Resources Monitoring Strategy (CWRMS). Since 2000, when the last CWRMS was published, numerous research projects and studies are demonstrating several new threats to the ecologic health and resilience of the SSER. Contemporary threats include: Eutrophic conditions brought on by high levels of nutrients from sewage treatment plant discharges, stormwater runoff, groundwater seepage, and atmospheric contributions; Increased occurrences of harmful algal blooms in the past 15 years; and, Growing concern...

Background Acidification of lotic and lentic environments has been found to adversely affect the integrity of resident biological assemblages. These effects have been particularly severe in poorly buffered regions like the Western Adirondacks. Although the Clean Air Act and its amendments have greatly reduced levels of atmospheric deposition, many streams in this region are still chronically or episodically acidified. In-stream and watershed-wide liming are two directed-mitigation techniques which could be used to accelerate ecosystem recovery and help restore the condition of biological assemblages. The costs and abilities (as well as effective duration) of these techniques to improve water and soil chemistry,...

Problem The Neversink River and Rondout Creek are historic trout fishing and recreational streams in the heart of the Catskill Mountains of southeastern NY. Waters throughout upper reaches of both rivers currently range from neutral to severely acidic due to deposition of acid rain throughout their watersheds. Fish surveys conducted by the USGS during the late 1980s and early 1990s found that some fish species and entire assemblages were absent or depressed in many tributaries and second and third order reaches of both rivers. Recent decreases in acidity of atmospheric deposition and changes in hydrologic and thermal regimes are now affecting water chemistry (e.g., pH, acid neutralizing capacity, dissolved organic...

Background Fish communities of the mainstem Mohawk River and Barge Canal have been well-documented (Carlson, 2015; George et al., 2016) but comparatively less information is available regarding the current status of fish communities in tributaries to the Mohawk River. This information gap is problematic because long-term shifts in species distributions or abundances due to climate change, eutrophication, or other anthropogenic stressors may go unnoticed in the absence of baseline data. More importantly, an approaching invasive fish species, the Round Goby (Neogobius melanostomus), is expected to colonize much of the Mohawk River and the lower portion of many major tributaries. Introductions of Round Goby have had...

How did this multi-LCC initiative develop? The framework for this landscape conservation design is objective-driven across three sectors for wildlife, water quality and agriculture – ultimately doing our part to strategically maximize the value of every conservation dollar for the Mississippi River Basin and Gulf of Mexico. An intensive year-long dialogue culminated in the Memphis workshop in August 2014, setting the stage for research and development of design tools this past year. For more information, see: https://www.fws.gov/science/catalog….What is the workshop purpose? Reconvene multi-sector participants to examine the set of high impact conservation practices, web-based spatial analysis tools, and research...

Description of Work The invasive form of Phragmites australis (common reed) is a well-established pest in many parts of the Great Lakes and the Atlantic, Gulf, and Pacific coasts, including designated Areas of Concern. New innovative control options that sustainably target the competitive advantage often enjoyed by Phragmites and other invasive plants will contribute to a broad Integrated Pest Management (IPM) strategy. This project targets the microorganisms that may help Phragmites spread and will employ a molecular genetic approach to silence the genes in Phragmites that give it a competitive edge over many native plants. This project helped build and will continue to be closely aligned with the Great Lakes Phragmites...

Problem Over the past century, the Harlem River watershed has become highly urbanized with 90 percent of the waterway constrained by infrastructure, which has limited access for recreational use. Bound by New York (Manhattan) and Bronx Counties, the Harlem River is a tidal strait between urbanized estuaries to the north (Hudson River) and south (East River). Direct inputs include the more than 50 combined sewer overflows (CSOs) that discharge runoff from impervious surfaces and untreated sewage to the Harlem River during precipitation events. Historic uses of the Harlem River included swimming, boating, and fishing, as well as horseback riding and hiking through adjacent parklands. As urban sprawl continued...

Background: The USGS propose a collaborative investigation with the NYSDEC and NOAA to evaluate the current condition of benthic macroinvertebrate communities and toxicity of bed sediments in the Niagara River Area of Concern (AOC). Using a probabilistic study design, sediment-toxicity data compiled by the USGS, invertebrate community data collected by NYSDEC, and sediment-chemistry data collected by NOAA will be assimilated using a Sediment Quality Triad approach (Chapman et al., 1992; USEPA, 1992) to provide a sediment-quality baseline needed to gauge changes expected to follow remediation of contaminated sediments in parts of the AOC. These data will also be used directly to confirm that the macroinvertebrate...

Background Discharges from non-point sources, municipal and industrial point sources, and combined sewage overflows over the last century resulted in elevated levels of heavy metals, conventional pollutants, phosphorus, and toxic organic contaminants in water and sediments of the Lower Genesee River and Rochester Embayment. As a result, the zooplankton and phytoplankton or “plankton” communities were designated as one of fourteen Beneficial Use Impairments (BUI); i.e., the resource was either impaired or in need of assessment in the Rochester Embayment Area of Concern (AOC). The Rochester Embayment Remedial Action Committee (RAC) was formed by the New York State Department of Environmental Conservation (NYSDEC)...

Problem - There is a stated need to provide information on loading of persistent toxic pollutants to Lake Ontario from New York tributaries. The information is specifically required for the Lake Ontario Mass Balance Model, which is an integral part of the long-term Great Lakes research. The project described here is designed to demonstrate a cost-effective approach for estimation of loads of polychlorinated-biphenyls (PCBs) through use of a relatively small number of large-volume whole-water samples for PCB analysis. The Black River basin was selected to demonstrate the feasibility of the approach because it is the largest New York contributor of PCBs to Lake Ontario. Objectives - The objective of this project...

Problem The Adirondack region of New York has 128 lakes that are listed as impaired by acidity under section 303(d) of the Clean Water Act. Acidity can limit the survival and reproduction of native fishes such as brook trout (Salvelinus fontinalis). Chronic and episodic acidification also stresses fish, aquatic macroinvertebrates, and other biota of inflowing tributaries of these and many additional lakes. Acidification of these tributaries can also affect the health of fish populations in receiving lakes, by limiting suitable spawning and nursery habitat. Although many Adirondack lakes have shown decreased acidity resulting from decreases in atmospheric sulfur and nitrogen emissions, the ecological improvements...

Problem - A variety of factors potentially impact natural resources in the Neversink River basin and in other tributaries to the Upper Delaware River along the New York, Pennsylvania, and New Jersey boarders in the northeastern US. Increased urbanization within most watersheds of the Delaware River has decreased forested lands and ground permeability; fractionated forests, streams, and rivers; impounded flowing waters, and discharged municipal, agricultural, and industrial pollutants into many waterways. The effects on water quality and hydrology have been quantified relatively well. The direct impacts of these perturbations on biological components of stream and river ecosystems are sometimes known, however, more...

Conclusions: Prescribed burns did not supply the stream ecosystem with potentially important nutrient pulses that are often observed after wildfires. Prescribing higher severity burns to more closely mimic wildfires would enhance N cycling in productivity in N-limited headwater watersheds. Thresholds/Learnings: Synopsis: This study aimed to compare the short-term effects of spring prescribed burns and wildfires on Nitrogen cycling dynamics in headwater watersheds of central Idaho. Fire affected N dynamics in both terrestrial and aquatic components of the watershed ecosystem after wildfires but were limited to the terrestrial ecosystem after prescribed burns. Streamwater NO3 concentrations were affected significantly...

The growth of temperate forests is typically limited by the availability of nitrogen. Elevated concentrations of nitrate in some Catskill Mountain streams, which are tributary to New York City's water-supply reservoirs west of the Hudson River, indicate that the forests of this region are at the early stages of nitrogen saturation. That is, nitrogen is available in excess of the amount utilized by vegetation and soil microorganisms in the forests. Nitrogen saturation is a concern because the mobile nitrate that moves through soil is accompanied by other nutrients such as the base cations calcium and magnesium that are necessary for forest growth but are present in short supply in some Catskill soils. And, nutrient...

Background With few exceptions, the contemporary and past effects of acidification on fish populations and communities in streams across acid-sensitive regions of NY have not been documented. The pervasive lack of information only permits anecdotal insight into the spatial effects of acidification on stream-fish assemblages and essentially precludes any broad effort to quantify temporal trends and potential recovery of fish assemblages in less acidic or less toxic streams. Though the effects of acidification on fish assemblages have been qualified in several streams of the eastern Adirondacks during 1979, the 1980s, and early 2000s, (Schofield and Driscoll 1987; Simonin et al. 2005) quantitative impacts were...

The Ellison Park wetland, a 423-acre, predominantly cattail marsh at the mouth of Irondequoit Creek in Monroe County near Rochester, N.Y., was evaluated for its potential role to decrease phosphorus loads that are derived from a 151-square-mile largely urbanized area and that ultimately enter and exacerbate efforts to ameliorate the eutrophic conditions in Irondequoit Bay. Monroe County's water-quality management plan included (1) modification of flow patterns upstream from and within the wetland by diverting storm runoff into backwater areas of the wetland, and (2) construction of a flow-control structure midway through the wetland that would cause short-term rises in water levels and increased dispersion of...

Description of Work The GLRI Rivermouths Project (template 82) is designed to enhance our understanding of how rivermouths function at both regional and local scales by 1) developing a rivermouth classification system, based on a broad scale database covering all Great Lakes rivermouths (>2000); 2) creating a science-based understanding of how the ecological structure and function of rivermouths are linked both to the landscapes they drain and to the Lakes with which they mix; and 3) increasing the public and scientific profile of these ecosystems by connecting researchers and natural resource managers through a collaborative dialog. The long-term goal is to provide enhanced guidance for restoration and rehabilitation...
