Global environmental change has influenced lake surface temperatures, a key driver of ecosystem structure and function. Recent studies have suggested significant warming of water temperatures in individual lakes across many different regions around the world. However, the spatial and temporal coherence associated with the magnitude of these trends remains unclear....

Ronald C. Johnson, Michael E. Brownfield
2015, Scientific Investigations Report 2013-5176
Halite and the sodium bicarbonate mineral nahcolite were deposited in Eocene-age saline Lake Uinta in the Piceance Basin, northwestern Colorado.

Bibliography for acid-rock drainage and selected acid-mine drainage issues related to acid-rock drainage from transportation activities
Mike Bradley, Scott C. Worland
2015, Open-File Report 2015-1016
Acid-rock drainage occurs through the interaction of rainfall on pyrite-bearing formations. When pyrite (FeS2) is exposed to oxygen and water in mine workings or roadcuts, the mineral decomposes and sulfur may react to form sulfuric acid, which often results in environmental problems and potential damage to the transportation infrastructure. The...

Scott W. Ator, Judith M. Denver
2015, Circular 1406
The Eastern Shore includes only a small part of the Chesapeake Bay watershed, but contributes disproportionately large loads of the excess nitrogen and phosphorus that have contributed to ecological and economic degradation of the bay in recent decades. Chesapeake Bay is the largest estuary in the United States and a...
A comparison of methods to predict historical daily streamflow time series in the southeastern United States
William H. Farmer, Stacey A. Archfield, Thomas M. Over, Lauren E. Hay, Jacob H. LaFontaine, Julie E. Kiang
2015, Scientific Investigations Report 2014-5231
Effective and responsible management of water resources relies on a thorough understanding of the quantity and quality of available water. Streamgages cannot be installed at every location where streamflow information is needed. As part of its National Water Census, the U.S. Geological Survey is planning to provide streamflow predictions for...
Water-quality trends for selected sites in the Boulder River and Tenmile Creek watersheds, Montana, based on data collected during water years 1997-2013
Steven K. Sando, Melanie L. Clark, Tom Cleasby, Elliott P. Barnhart
2015, Scientific Investigations Report 2015-5008
In the Boulder River and Tenmile Creek watersheds in southwestern Montana, there was intensive mining during a 40-year period after the discovery of gold in the early 1860s.

Modelling non-Euclidean movement and landscape connectivity in highly structured ecological networks
Christopher Sutherland, Angela K. Fuller, J. Andrew Royle
2015, Methods in Ecology and Evolution (6) 169-177
Movement is influenced by landscape structure, configuration and geometry, but measuring distance as perceived by animals poses technical and logistical challenges. Instead, movement is typically measured using Euclidean distance, irrespective of location or landscape structure, or is based on arbitrary cost surfaces. A recently proposed extension of spatial...

Nathan J. Hostetter, Allen F. Evans, Bradley M. Cramer, Ken Collis, Donald E. Lyons, Daniel D. Roby
2015, Transactions of the American Fisheries Society (144) 410-422
Accurate assessment of specific mortality factors is vital to prioritize recovery actions for threatened and endangered species. For decades, tag recovery methods have been used to estimate fish mortality due to avian predation. Predation probabilities derived from fish tag recoveries on piscivorous waterbird colonies typically reflect minimum estimates of predation...

Buried particulate organic carbon stimulates denitrification and nitrate retention in stream sediments at the groundwater-surface water interface
Robert S. Stelzer, J. Thad Scott, Lynn Bartsch
2015, Freshwater Science (34) 161-171
The interface between ground water and surface water in streams is a hotspot for N processing. However, the role of buried organic C in N transformation at this interface is not well understood, and inferences have been based largely on descriptive studies. Our main objective was to determine how buried...
Multiple regression and inverse moments improve the characterization of the spatial scaling behavior of daily streamflows in the Southeast United States
William H. Farmer, Thomas M. Over, Richard M. Vogel
2015, Water Resources Research (51) 1775-1796
Understanding the spatial structure of daily streamflow is essential for managing freshwater resources, especially in poorly-gaged regions. Spatial scaling assumptions are common in flood frequency prediction (e.g., index-flood method) and the prediction of continuous streamflow at ungaged sites (e.g. drainage-area ratio), with simple scaling by drainage area being the most...

Matthew P. Miller, Henry M. Johnson, David D. Susong, David M. Wolock
2015, Journal of Hydrology (522) 203-210
Understanding how watershed characteristics and climate influence the baseflow component of stream discharge is a topic of interest to both the scientific and water management communities. Therefore, the development of baseflow estimation methods is a topic of active research. Previous studies have demonstrated that graphical hydrograph separation (GHS) and conductivity...

Michael R. Meador, Larry M. Brown
2015, Environmental Biology of Fishes (98) 663-677
Predictive models have been used to determine fish species that occur less frequently than expected (decreasers) and those that occur more frequently than expected (increasers) in streams in the eastern U.S. Coupling life history traits with 51 decreaser and 38 increaser fish species provided the opportunity to examine potential mechanisms...
