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.

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.

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.

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.

Great blue herons, yellow birches, damselflies, and beavers are among the talismans by which Bill Roorbach uncovers a natural universe along the stream that runs by his house in Farmington, Maine. Populated by an oddball cast of characters to whom Roorbach ("The Professor") and his family might always be considered outsiders, this book chronicles one man's determined effort-occasionally with hilarious results-to follow his stream to its elusive source. Acclaimed essayist and award-winning fiction writer Bill Roorbach uses his singular literary gifts to inspire us to laugh, love, and experience the wonder of living side by side with the natural world.

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.
