Water scarcity is a growing concern in Texas, where surface water is derived almost entirely from rainfall. Changes in air temperature and precipitation patterns associated with global climate change are anticipated to regionally affect the quality and quantity of inland surface waters and consequently their suitability as habitat for freshwater life. In addition to directly affecting resident organisms and populations, these changes in physicochemical traits of aquatic habitats may favor the establishment of harmful invasive species. As conflicts over the use of water resources grow in intensity, this information will become important for fish and wildlife managers to anticipate impacts of climate change on trust...

The Imiq Hydroclimate Database houses hydrologic, climatologic, and soils data collected in Alaska and Western Canada from the early 1900s to the present. This database unifies and preserves numerous data collections that have, until now, been stored in field notebooks, on desktop computers, as well as in disparate databases. Synthesizing and analyzing the large-scale hydroclimate characteristics of this important climatic region have been made easier with this searchable database. The data, originally collected in a Microsoft SQL Server 2008 relational database, has been migrated to an open source PostgreSQL and PostGIS environment. The Imiq Data Portal provides public access to portions of the Imiq Hydroclimate...

The Terrestrial Environmental Observation Network (TEON) is intended to meet the need for a sustainable environmental observing network for northern Alaska. The TEON plan proposes collection of a time series of specific environmental variables in seven representative watersheds across northern Alaska. The Kuparuk River watershed is central to this plan both because of its location that bisects Alaska’s North Slope and its record of hydroclimatic data and research now surpassing 30-yrs. Nested catchments within and adjacent to this sentinel Arctic river system integrate climate and landscape responses from the Brooks Range foothills (Imnavait Creek and Upper Kuparuk River) to the Arctic Coastal Plain (Putuligayuk...

The mottled duck, a focal species for the Gulf Coast Prairie Landscape Conservation Cooperative, is one of only a few duck species adapted to breeding in southern marshes. A major part of its population spends its entire life cycle within a relatively small coastal area in eastern Texas and western Louisiana. This is a thriving part of the Mississippi and Central Flyways, two of four major waterfowl migration routes in North America. In recent years, the mottled duck’s habitat and surrounding areas have been compromised by urbanization, agricultural development, and changes to the area’s hydrology affecting coastal wetlands. The latter threat includes the ramifications of climate change, such as sea level rise and...

The Red River Stakeholder Engagement project’s primary objective was to uncover areas of concern for stakeholders who live, work, and play along the Red River Basin. It examined the complexity of the cultural-geographic landscape across the Red River Basin. By focusing on both the geographic and the cultural, we gain a better understanding of how individuals, communities, and organizations interact with the basin and with one another, how they are currently experiencing changes, and what they perceive a changing climate means for them. This cultural-geographic approach recognizes that stakeholders’ concerns, priorities, and actions likely vary across space-and also vary in their cultural significance. For example,...

Summary The Environmental Protection Agency’s (EPA) Long Term Monitoring (LTM) network has supported the collection of stream chemistry data in the Catskills since the 1990s. Trends in stream chemistry have periodically been evaluated in these streams but the most recent assessments only extend through the early 2000s. An updated assessment of stream chemistry trends will help evaluate the effects of recent substantial declines in acid deposition during the last decade. This study will evaluate changes in surface water chemistry from 1991 through 2013 at 5 stations in the Neversink and Rondout watersheds in the Catskill Mountains of New York. The results will be compared to changes in atmospheric deposition...

Introduction As a result of storage and disposal practices at a former Manufactured Gas Plant, or MGP, in Bay Shore, NY, a variety of polycyclic aromatic hydrocarbons (PAHs) have been detected at high concentrations in the surficial, upper glacial aquifer of Long Island. Levels of PAHs initially detected over 10 years ago were in the parts-per-thousand range within a groundwater contaminant plume. The plume extended over a half-mile from MGP-related sources to discharge at a local estuarine tributary, Lawrence Creek, resulting, resulting in malodorous hydrocarbon sheens in this tributary and nearby storm drains. These signs of contamination revealed a larger underlying problem and prompted calls by state and local...

Problem - Acidic precipitation has affected forested and aquatic ecosystems in New York, particularly in the Adirondack and Catskill regions. Acidification of surface waters and deleterious effects on fish and other biota have been well documented in both these regions. Despite reduced levels of acidity in atmospheric deposition over the past 20 years across New York and the northeastern United States, the most acid-sensitive streams and lakes have not yet begun to recover, and many show continued declines in acid-neutralizing capacity, an indicator acid-base status. Many studies have documented the effects of acid precipitation in New York, but thus far, there has been no comprehensive effort to synthesize and...
The Desert LCC will provide the 50% of the Federal component of funds, and the work designed will support the science objectives for the Desert LCC and its partners as well as provide needed improvements to the National Hydrography Dataset (NHD) in the Lower Colorado River Region, and beyond. Basic improvement of the NHD at the 1:24,000 scale will provide an important framework basis for the development of hydrologic models required to address effects of climate change. An accurate surface water map will support the following specific DLCC objectives and needs: Hydrologic and biological modeling Accurate determination of perennial and intermittent classification Impacts on flow due to storms (particularly in the...

The Red River Basin of New Mexico, Oklahoma, Texas, Arkansas, and Louisiana was chosen as a focus area study (FAS) as part of the U.S. Geological Survey (USGS) National Water Census (NWC). The objective of the NWC is to place technical information and tools in the hands of stakeholders so that they can make decisions on water availability. With this set objective, the USGS Water Science Centers in New Mexico, Oklahoma, Texas, Arkansas, and Louisiana conducted a study of water use and availability for the Red River Basin to improve water withdrawal estimates and investigate trends in water resources under future climate conditions and increased water withdrawals using groundwater and surface-water models (MODFLOW...

Problem - The valley-fill deposits in Upper Buttermilk Creek/Danby Creek valleys are sources of water for many homeowners, farms, and small businesses that are in this valley. The aquifer was mapped by Miller (2000) and identified as one of the 17 aquifers in Tompkins County that needs to be studied in more detail. However, there is little geohydrologic data in the valley. A cluster of wells in Upper Buttermilk valley are finished in sand and gravel, indicating that there is a sand and gravel aquifer in, at least, part of the valley. The Upper Buttermilk Creek/Danby Creek valleys are "through valleys"-- a part of a valley where the bedrock floor rose to land surface and formed a preglacial surface-water divide....

The Southeast Aquatic Resources Partnership, a partner in the Gulf Coast Prairie Landscape Conservation Cooperative, is advancing instream flow science by developing basic information necessary to support flow standards and water management recommendations for waterways throughout the region. Helping resource managers prepare for future population growth and climate change-associated flow alterations at regional and local scales will enable state and federal agencies to focus regulatory and management efforts on habitats most vulnerable to altered flow. They will be able to develop more effective management strategies to minimize impacts to fish and wildlife and better inform policy-makers on conservation needs.

Alligator Gar, Atractosteus spatula, is an iconic species native to lowland floodplain river systems where they play an important role as top predators and by linking landscapes through their movement. Alligator Gar is also an important native fisheries species in the Trinity River. Disruption of river-floodplain connectivity is implicated in declining populations of Alligator Gar across much of its range. Successful management and conservation of Alligator Gar populations will be aided by an understanding of the relationship between flow and recruitment, particularly the availability and suitability of off-channel habitats utilized by this species for reproduction.

Problem The quality of surface water has important effects on human and ecological health. Surface water is an important drinking water source and is used for swimming, fishing, and recreation, and the quality of surface water can have profound effects on the health, diversity, and resilience of ecological communities. The New York State Department of Environmental Conservation (NYSDEC) is tasked by the U.S. Environmental Protection Agency (USEPA) to monitor ambient water quality of the State. The NYSDEC is also tasked to develop Total Maximum Daily Loads (TMDLs) for state waters that fail to meet their intended use. A critical first step in maintaining high quality of surface-water is assessment of existing...

Problem The New York City Department of Environmental Protection (NYCDEP) has asked the U.S. Geological Survey (USGS) to assist in two major studies: 1) delineation of the source(s) of shallow groundwater and the extent that the Delaware Aqueduct is contributing to local flooding issues, and 2) delineation of the structural, geologic, and hydrologic conditions along proposed tunnel construction paths using advanced surface and borehole geophysical methods. The NYCDEP needs to determine the source of groundwater and surface water and their possible relation to leakage from the Delaware Aqueduct in upstate New York. The Delaware Aqueduct, which supplies a significant portion of New York City's water supply, has...

The Russian River Watershed (RRW) covers about 1,300 square miles (without Santa Rosa Plain) of urban, agricultural, and forested lands in northern Sonoma County and southern Mendocino County, California. Communities in the RRW depend on a combination of Russian River water and groundwater to meet their water-supply demands. Water is used primarily for agricultural irrigation, municipal and private wells supply, and commercial uses - such as for wineries and recreation. Annual rainfall in the RRW is highly variable, making it prone to droughts and flooding from atmospheric river events. In order to better understand surface-water and groundwater issues, the USGS is creating a Coupled Ground-Water and Surface-Water...

We propose to empirically characterize hydrology/fish-production relationships for different ecological groups of fishes living in the Red River and associated reservoir habitats by: 1. Correlating historic hydrologic data with catch curve residuals, and 2. Annual growth rate estimates of fish collected from the Red River and associated reservoirs. The catch curve residual approach for indexing year class strength has been validated and successfully used to quantify the relationship between reservoir hydrology and YOY recruitment for white crappie and largemouth. The essence of the approach is as follows. Catch curves (a correlation between the natural log of fish abundance and age) are used to measure total instantaneous...
