Water samples were collected from 25 production and domestic wells in the Upper Hudson River Basin from August through November 2007 to characterized the groundwater quality. The Upper Hudson River Basin covers 4,600 square miles in the upstate New York, Vermont, and Massachusetts; the study area encompasses the 4,000 square miles that lie within New York.

A study of the Withlacoochee River watershed in west-central Florida was conducted from October 2003 to March 2007 to gain a better understanding of the hydrology and surface-water and groundwater interactions along the river. The Withlacoochee River originates in the Green Swamp area in north-central Polk County and flows northerly through seven counties, emptying into the Gulf of Mexico. This study includes only the part of the watershed located between the headwaters in the Green Swamp and the U.S. Geological Sur-vey gaging station near Holder, Florida. The Withlacoochee River within the study area is about 108 miles long and drains about 1,820 square miles.

A one-dimensional daily averaged water temperature model was used to simulate Klamath River temperatures for two management alternatives under historical climate conditions and six future climate scenarios.

Anthropogenic influenced to the Kootenai River is evident upstream of, in, and downstream of the federally designed critical habitat reach of the Kootenai River populations of white sturgeon.

We compared cui-ui (Chasmistes cujus) recruitment from two reaches of the Truckee River with histories of severe erosional downcutting caused by a decline in Pyramid Lake surface elevation. In 1975, Marble Bluff Dam (MBD) was constructed 5 kilometers upstream of the extant mouth of the Truckee River to stabilize the upstream reach of the river; the downstream reach of the river remained unstable and consequently unsuitable for cui-ui recruitment. By the early 2000s, there was a decrease in the Truckee River's slope from MBD to Pyramid Lake after a series of wet years in the 1990s. This was followed by changes in river morphology and erosion abatement. These changes led to the question as to cui-ui recruitment potential in the Truckee River downstream of MBD. In 2012, more than 7,000 cui-ui spawners were passed upstream of MBD, although an indeterminate number of cui-ui spawned downstream of MBD. In this study, we compared cui-ui recruitment upstream and downstream of MBD during a Truckee River low-flow year (2012). Cui-ui larvae emigration to Pyramid Lake began earlier and ended later downstream of MBD.

The lower Chetco River is a wandering gravel-bed river flanked by abundant and large gravel bars formed of coarse bed-material sediment. The large gravel bars have been a source of commercial aggregate since the early twentieth century for which ongoing permitting and aquatic habitat concerns have motivated this assessment of historical channel change and sediment transport rates. Analysis of historical channel change and bed-material transport rates for the lower 18 kilometers show that the upper reaches of the study area are primarily transport zones, with bar positions fixed by valley geometry and active bars mainly providing transient storage of bed material. Downstream reaches, especially near the confluence of the North Fork Chetco River, have been zones of active sedimentation and channel migration.

The Yukon River Inter-Tribal Watershed Council and the U.S. Geological Survey developed a water-quality monitoring program to address a shared interest in the water quality of the Yukon River and its relation to climate. This report contains water-quality data from samples collected in the Yukon River Basin during water years 2006 through 2008. A broad range of chemical analyses from 44 stations throughout the YRB are presented. On August 8, 2009 the USGS signed a Memorandum of Understanding with the Yukon River Inter-Tribal Watershed Council representing the culmination of 5 years of dedicated efforts to forge a working collaboration and partnership with expectations of continuing into the foreseeable future.

The Chemehuevi Formation forms a conspicuous, widespread, and correlative set of nonmarine sediments lining the valleys of the Colorado River and several of its larger tributaries in the Basin and Range geologic province. These sediments have been examined by geologists since J. S. Newberry visited the region in 1857 and are widely cited in the geologic literature; however their origin remains unresolved and their stratigraphic context has been confused by inconsistent nomenclature and by conflicting interpretations of their origin.

New River Gorge National River (NERI) began its General Management Plan (GMP) planning process in 2004 to ensure that the park has a clearly defined direction for resource conservation and visitor use. The NERI GMP should be based on current scientific and scholarly understanding of park natural (and cultural) resources and make certain that planning decisions are consistent with park purposes. Toward that goal, this report seeks to provide an assessment of the currently available natural resource knowledge relating to NERI. This report provides usable, understandable, and transferable information about the current status and significance of, threats to, and gaps in knowledge about, the natural resources at NERI. In addition, this report provides suggested management recommendations to help ensure the proper stewardship of the natural resources at NERI.

In 2006, we collected larval Lost River sucker Deltistes luxatus (LRS), shortnose sucker Chasmistes brevirostris (SNS), and Klamath largescale sucker Catostomus snyderi (KLS) emigrating from spawning areas in the Williamson and Sprague Rivers. This work is part of a multi-year effort to characterize the relative abundance, drift timing, and length frequencies of larval suckers in this watershed prior to the removal of Chiloquin Dam on the lower Sprague River. Additional larval drift samples were collected from the Fremont Bridge on Lakeshore Drive on the south end of Upper Klamath Lake near its outlet to the Link River. Because of difficulties in distinguishing KLS larvae from SNS larvae, individuals identified as either of these two species were grouped together and reported as KLS-SNS in this report.

In 2003, the National Park Service (NPS) at New River Gorge National River (NERI) hosted a workshop to identify significant forest issues, resources, and processes occurring within the park (National Park Service 2003b). Several forest communities of concern were identified by the panel of scientists and resource managers. One such community, the rimrock pine forest lining the rim of the gorge, was chosen due to the importance of the community to wildlife and recreation. The rimrock pines also were thought to be a historically significant feature of the northern section of the gorge as evidenced by historic photographs from the 1940s and 1950s. The panel suggested an investigation be conducted to better understand the establishment and maintenance of the rimrock pine forest.

A floristic inventory of Bluestone National Scenic River, located in southern West Virginia, was conducted from 2003 to 2006 by the West Virginia Natural Heritage Program. Prior to field work, literature and databases were reviewed to compile a list of vascular plants already known to occur in Bluestone National Scenic River. Six hundred sixty-eight vascular plant taxa were identified during the 2003-2006 field surveys including 367 taxa not previously documented from the study area.

The South Yuba River (SYR), located on the western portion of the Sierra Nevada in California, is highly contaminated with mercury (Hg) as a result of historical gold (Au) mining that took place throughout this region starting in the mid 1800s and continuing into the early 1900s. During this period, the hydraulic mining of alluvial Au deposits formed during the Tertiary period (65.5 to 2.6 million years before present) was responsible for mobilizing hundreds of millions of tons of hydraulic mining debris (HMD), which was and continues to be redeposited in the SYR, its tributaries, and the San Francisco Bay Delta. Hydraulic mining was used in combination with the mercurygold (Hg-Au) amalgamation process. Elemental mercury (Hg(0)) was introduced into Au recovery sluices to trap Au flakes, which were mixed with the sediment-water slurry produced from the hydraulic mobilization of sediment. As a result of inefficient trapping, some amount of both Hg(0) and Hg-Au amalgam was lost in this process. And along with the HMD, both can still be found throughout the SYR watershed, downstream of the major historic mining areas.

Examining the science of stream restoration, Rebecca Lave argues that the neoliberal emphasis on the privatization and commercialization of knowledge has fundamentally changed the way that science is funded, organized, and viewed in the United States.
Stream restoration science and practice is in a startling state. The most widely respected expert in the field, Dave Rosgen, is a private consultant with relatively little formal scientific training. Since the mid-1990s, many academic and federal agency-based scientists have denounced Rosgen as a charlatan and a hack. Despite this, Rosgen's Natural Channel Design approach, classification system, and short-course series are not only accepted but are viewed as more legitimate than academically produced knowledge and training. Rosgen's methods are now promoted by federal agencies including the Environmental Protection Agency, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the Natural Resources Conservation Service, as well as by resource agencies in dozens of states.
Drawing on the work of Pierre Bourdieu, Lave demonstrates that the primary cause of Rosgen's success is neither the method nor the man but is instead the assignment of a new legitimacy to scientific claims developed outside the academy, concurrent with academic scientists' decreasing ability to defend their turf. What is at stake in the Rosgen wars, argues Lave, is not just the ecological health of our rivers and streams but the very future of environmental science.

Is there enough water on this planet for a global population that will shortly double its present size? The answer is of huge importance for people everywhere, but particularly to the peoples and political leaders of the Middle East and North Africa. As well as explaining the particular issues of conflict in the region, Allan argues that the answer to these problems lies at the global rather than local level. The Middle East Water Question is a major book by one of the world's leading authorities on water issues.

One of the last undammed perennial rivers in the desert Southwest, the San Pedro River in southeastern Arizona illustrates important processes common to many desert riparian ecosystems. Although historic land uses and climatic extremes have led to aquifer depletion, river entrenchment, and other changes, the river still sustains a rich and varied selection of life. Resilient to many factors, portions of the San Pedro have become increasingly threatened by groundwater pumping and other impacts of population growth.
This book provides an extensive knowledge base on all aspects of the San Pedro, from flora and fauna to hydrology and human use to preservation. It describes the ecological patterns and processes of this aridland river and explores both the ongoing science-driven efforts by nonprofit groups and government agencies to sustain and restore its riparian ecosystems and the science that supports these management decisions.
An interdisciplinary team of fifty-seven contributors--biologists, ecologists, geomorphologists, historians, hydrologists, lawyers, political scientists--weave together threads from their diverse perspectives to reveal the processes that shape the past, present, and future of the San Pedro's riparian and aquatic ecosystems. They review the biological communities of the San Pedro and the stream hydrology and geomorphology that affect its riparian biota. They then look at conservation and management challenges along three sections of the San Pedro, from its headwaters in Mexico to its confluence with the Gila River, describing legal and policy issues and their interface with science; activities related to mitigation, conservation, and restoration; and a prognosis of the potential for sustaining the basin's riparian system.
These chapters demonstrate the complexity of the San Pedro's ecological and hydrological conditions, showing that there are no easy answers to the problems--and that existing laws are inadequate to fully address them. Collectively, they offer students, professionals, and environmental advocates a better grasp of the San Pedro's status as well as important lessons for restoring physical processes and biotic communities to rivers in arid and semiarid regions.

Riparian zones encompass the stream channel and the adjacent portion of the terrestrial landscape from the high water mark toward the uplands, where vegetation might be influenced by elevated water tables or flooding. In this book, the authors present topical research in the study of the protection, restoration and ecological benefits of riparian zones. Topics discussed in this compilation include fire regimes, sand structure, fuel loads and fire behaviour in riparian forests of the Sierra Nevada Mountains, USA; the ecological and socio-economic stakes for conserving and protecting riparian forests in West Africa; ground water chemistry under riparian zones; and protection of riparian landscapes in Israel.

The story of the Santee is, in fact, the story of a major part of the Carolinas east of the Appalachians, for the river drains an immense area of both states from the mountains to the ocean. Savage also describes fully the change-over from the agricultural Old South to the industrial New South, a change sparked largely by the hydroelectric power of the Santee.
