SEATTLE — The effects of dam removal are better known as a result of several new studies released this week by government, tribal and university researchers. The scientists worked together to characterize the effects of the largest dam removal project in U.S. history occurring on the Elwha River of Washington State. New findings suggest that dam removal can change landscape features of river and coasts, which have ecological implications downstream of former dam sites.
“These studies not only give us a better understanding of the effects of dam removal, but show the importance of collaborative science across disciplines and institutions,” said Suzette Kimball, acting director of the U.S. Geological Survey.
Five peer-reviewed papers, with authors from the U.S. Geological Survey, Reclamation, National Park Service, Washington Sea Grant, NOAA Fisheries, the Lower Elwha Klallam Tribe, and the University of Washington, provide detailed observations and insights about the changes in the river’s landforms, waters and coastal zone during the first two years of dam removal. During this time, massive amounts of sediment were eroded from the drained reservoirs and transported downstream through the river and to the coast.
One finding that intrigued scientists was how efficiently the river eroded and moved sediment from the former reservoirs; over a third of the 27 million cubic yards of reservoir sediment, equivalent to about 3000 Olympic swimming pools filled with sediment, was eroded into the river during the first two years even though the river’s water discharge and peak flows were moderate compared to historical gaging records.
This sediment release altered the river’s clarity and reshaped the river channel while adding new habitats in the river and at the coast. In fact, the vast majority of the new sediment was discharged into the coastal waters of the Strait of Juan de Fuca, where the river mouth delta expanded seaward by hundreds of feet.
“The expansion of the river mouth delta is very exciting, because we are seeing the rebuilding of an estuary and coast that were rapidly eroding prior to dam removal,” said USGS research scientist and lead author of the synthesis paper, Dr. Jonathan Warrick.
Although the primary goal of the dam removal project is to reintroduce spawning salmon runs to the pristine upper reaches of the Elwha River within Olympic National Park, the new studies suggest that dam removal can also have ecological implications downstream of the former dam sites. These implications include a renewal of the sand, gravel and wood supplies to the river and to the coast, restoring critical processes for maintaining salmon habitat to river, estuarine and coastal ecosystems.
“These changes to sediment and wood supplies are important to understand because they affect the river channel form, and the channel form provides important habitat to numerous species of the region,” stated USGS research scientist and river study lead author, Dr. Amy East.
The final stages of dam removal occurred during the summer of 2014. Some sediment erosion from the former reservoirs will likely continue. The Elwha Project and research teams are continuing to monitor how quickly the river returns to its long-term restored condition.
“We look forward to seeing when the sediment supplies approach background levels,” said Reclamation engineer and co-author, Jennifer Bountry, “because this will help us understand the length of time that dam removal effects will occur.”
The five new papers can be found in Elsevier’s peer-reviewed journal, Geomorphology, and they focus on the following topics of the large-scale dam removal on the Elwha River, Washington (web-based publication links using digital object identifiers, doi, are provided in parentheses):
- Erosion of reservoir sediment
- Fluvial sediment load
- River channel and floodplain geomorphic change
- Coastal geomorphic change
- Source-to-sink sediment budget and synthesis
Newly released US Topo maps for Nevada now feature selected trails. The data for the trails is provided to the USGS through a nation-wide “crowdsourcing” project managed by the International Mountain Biking Association (IMBA). Several of the 1,785 new US Topo quadrangles for the state now display public trails along with other improved data layers such as land survey information (PLSS), map symbol redesign and new road source data.
"Users of the US Topo maps in our state are excited about the release of these new versions," said Carol Ostergren, The National Map Liaison for Nevada. "Nevada features numerous trails, so the addition of several mountain bike trails will increase the use of the new US Topo maps. Also, adding PLSS will assist many of our users who have been asking for that data for a long time."
For Nevada residents and visitors who want to explore the stunning desert landscape on a bicycle seat or hiking shoes, the new trail features on the US Topo maps will come in handy. During the past two years the IMBA, in a partnership with the MTB Project, has been building a detailed national database of mountain bike trails. This activity allows local IMBA chapters, IMBA members and the public to provide trail data and descriptions through their website. MTB Project and IMBA then verify the quality of the trail data provided and ensure accuracy and confirm that the trail is legal. This unique crowdsourcing venture has increased the availability of trail data available through The National Map mobile and web apps, and the revised US Topo maps.
Another important addition to the new Nevada US Topo maps is the inclusion of Public Land Survey System data. PLSS is a way of subdividing and describing land in the United States. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior.
These new maps replace the first edition US Topo maps for Nevada and are available for free download from The National Map, the USGS Map Locator & Downloader website , or several other USGS applications.
To compare change over time, scans of legacy USGS topo maps, some dating back to the late 1800s, can be downloaded from the USGS Historical Topographic Map Collection.

A new U.S. Geological Survey study shows how plants’ vulnerability to drought varies across the landscape; factors such as plant structure and soil type where the plant is growing can either make them more vulnerable or protect them from declines.
Recent elevated temperatures and prolonged droughts in many already water-limited regions throughout the world, including the southwestern U.S., are likely to intensify according to future climate model projections. This warming and drying can negatively affect vegetation and could lead to the degradation of wildlife habitat and ecosystems. It is critical for resource managers and other decision-makers to understand where on the landscape vegetation will be affected so they can prioritize restoration and conservation efforts, and plan for the future.
To better understand the potential detrimental effects of climate change, USGS scientists developed a model to evaluate how plant species will respond to increases in temperature and drought. The model integrates knowledge about how plant responses are modified by landscape, soil and plant attributes that are integral to water availability and use. The model was tested using fifty years of repeat measurements of long-living, or perennial, plant species cover in large permanent plots across the Mojave Desert, one of the most water-limited ecosystems in North America. The report, published in the Journal of Ecology, is available online.
“The impacts of drought are not going away, and sound science to understand how water-limited ecosystems will respond is important for managers to plan climate adaptation strategies,” said Seth Munson, USGS scientist and lead author of the study. “By using monitoring results that scientists and managers have diligently reported for the last several decades, our study helps forecast the future state of drylands.”
Results show that plants respond to climate differently based on the physical attributes of where they are growing in the Mojave Desert. For example, deep-rooted plants were not as vulnerable to drought on soils that allowed for deep-water flow. Also, shallow-rooted plants were better buffered from drought on soils that promoted water retention near the surface. This information may be helpful for resource managers to minimize disturbance in areas that are likely vulnerable to water shortages.
Water moves horizontally and vertically through the landscape, which affects the amount of water plants can take up through their roots. There is more to plant water availability and use than the precipitation that falls out of the sky. Understanding how water moves through ecosystems is critical in regions that already have marginal water available for plant growth. Predicting climate change impacts in these areas requires more than an understanding of climate alone.
This study was done in cooperation with the University of Arizona, the Fort Irwin Directorate of Public Works, Utah State University, University of Nevada, California Polytechnic State University, Ohio State University, California State University and the National Park Service.
RESTON, Va.-- Aftershocks from the 2011 Virginia earthquake have helped scientists identify the previously unknown fault zone on which the earthquake occurred. The research marked one of the few times in the Eastern United States that a fault zone on which a magnitude-5-or-more earthquake occurred was clearly delineated by aftershocks, and is just one finding in a 23-chapter book with new information on the Virginia earthquake and eastern seismic hazards.
Research by the U.S. Geological Survey along with its partners and collaborators defined the newly recognized fault zone, which has been named the “Quail” fault zone. USGS and others worked cooperatively in an effort to capture the accurate locations of hundreds of aftershocks by deploying portable seismic instruments after the earthquake. Most of these aftershocks were in the Quail fault zone, and outlying clusters of shallow aftershocks helped researchers to identify and locate other active faults. Knowing where to look for the active faults helped to focus geologic mapping, geophysical imaging and other technologies to better understand earthquakes in the Central Virginia Seismic Zone and Eastern U.S.
The book includes contributions by Virginia Tech, the Virginia Department of Mines, Minerals, and Energy and the U.S. Nuclear Regulatory Commission among many others.
“Studies of the Virginia earthquake have improved our understanding of earthquakes and seismic hazards in Eastern North America,” said USGS geologist Wright Horton. “The Virginia earthquake served as a ‘wakeup call’ for many residents of the Eastern U.S., where the probability of major earthquakes is fairly low, but many buildings are vulnerable to damage during earthquakes.”
The new book, “The 2011 Mineral, Virginia, Earthquake, and Its Significance for Seismic Hazards in Eastern North America”, is a collection of articles that covers a broad range of subjects relating to the 2011 earthquake. Highlights from the book include:
- Earthquake shaking and its effects, such as widespread changes in groundwater levels, occurred at greater distances from the source in this and other Eastern U.S. earthquakes as opposed to those of comparable magnitude on the West Coast
- Shaking intensities and related damage were more severe along the northeast trend of the Appalachians than in northwestward directions across this trend
- Evidence that the earthquake ground motion was amplified in parts of D.C. and other areas around the Chesapeake Bay with thicker coastal plain sediments or artificial fill is stimulating further studies to determine how much seismic shaking is amplified by local geological conditions
- Analysis of data on residential property damage in the epicentral area delineates a “bulls eye” distribution of shaking intensities and also confirms that damage is influenced by the age and construction of homes
- Damage to unreinforced masonry buildings in D.C., as far as 80 miles from the epicenter, highlights the seismic risk to buildings in Eastern North American cities. Ground motions occur at farther distances from the epicenter on the East Coast than other parts of the U.S., and buildings are not as well designed to sustain these motions as in other locations
- Seismic reflection imaging—which is similar to medical sonograms—and geophysical flight surveys of the Earth’s magnetic and gravity fields were used to image geologic structures down to about 5 miles underground where the earthquake occurred
- Airborne laser swath mapping using lidar, and radiometric flight surveys—which mapped radioactive elements in rocks and soils within a few feet of the land surface—identified and accurately located preexisting linear features including faults associated with aftershock clusters for detailed surface geologic mapping and trenching studies
- New geologic mapping and trenching reveal previously unknown faults and evidence that the faults were active more than once in the past
- Recorded ground motions from the Virginia earthquake were consistent with previous USGS estimates for the region, and they are helping to improve the assessments of potential earthquake ground motions used to design buildings that will be better able to withstand strong earthquakes
Earthquakes in Eastern North America are not as frequent or as well understood as those along Earth's tectonic plate boundaries, such as on the West Coast. The magnitude 5.8 Virginia earthquake was the largest to occur in the eastern U.S. since the 1886 earthquake near Charleston, South Carolina, and it may have been felt by more people than any other earthquake in U.S. history. It was felt over much of the Eastern U.S. and Southeastern Canada, triggered the automatic safe shutdown of a nuclear power plant and caused significant damage from Central Virginia to the National Capital Region. The earthquake provided a wealth of modern scientific and engineering data to better understand earthquakes and seismic hazards in Eastern North America.

DENTON, Texas — The Federal Emergency Management Agency (FEMA) provided more than $43 million in 2014 funding to the Arkansas Department of Emergency Management (ADEM) and community partners for disaster recovery, mitigation and preparedness.
“FEMA, in partnership with ADEM, continues to provide funding to assist communities recovering from and mitigating against future damage,” said FEMA Region 6 Administrator Tony Robinson. “We are committed to helping Arkansas residents strengthen their resilience.”
The President’s fiscal year 2016 budget request for the U.S. Geological Survey is $1.2 billion, an increase of nearly $150 million above the FY 2015 enacted level. The FY16 budget reflects the vital role the USGS plays in advancing the President’s ongoing commitment to scientific discovery and innovation to support a robust economy, sustainable economic growth, natural resource management, and science-based decision-making for critical societal needs.
The budget request includes increases that ensure the USGS is at the leading edge of earth sciences research. It includes robust funding for science to inform land and resource management decisions, advance a landscape-level understanding of ecosystems, and develop new information and strategies to support communities in responding to climate change, historic drought, water quality issues, and natural hazards. The budget also funds science to support the Nation’s energy strategy, to help identify critical mineral resources, and to address the impacts of energy and mineral development on the environment.
“The USGS has a strong 136-year legacy of providing reliable science to decision-makers,” said Suzette Kimball, Acting USGS Director. “This budget request recognizes our unique capabilities with multi-disciplinary earth science research and will allow the USGS to meet societal needs for our Nation now and in the future.”
Key increases in the FY 2016 Budget are summarized below. For more detailed information on the President’s 2016 budget, visit the USGS Budget, Planning, and Integration website.
Meeting Water Challenges in the 21st Century
The FY16 budget provides an increase of $14.5 million above the FY 2015 enacted level for science to support sustainable water management. Meeting the Nation’s water resource needs poses increasing challenges for resource managers, who must contend with changes in the frequency and magnitude of floods and droughts. As competition for water resources grows for activities such as farming, energy production, and community water supplies, so does the need for information and tools to aid decision-makers. The budget provides increased funding across several USGS mission areas to support resource managers in understanding and managing competing demands related to water availability and quality and to enable adaptive management of watersheds to support the resilience of the communities and ecosystems that depend on them. This includes a $3.2 million increase for science to understand and respond to drought, a $4 million increase for water use information and research, a $2.5 million increase to study ecological water flows, a $1.3 million increase for stream flow information, and a $1.0 million increase to advance the National Groundwater Monitoring Network.
Powering Our Future and Supporting Sustainable Energy and Mineral Development
The 2016 USGS budget provides $9.6 million in program increases across the energy, minerals and environmental health portfolio for science to support the sustainable development of unconventional oil and gas resources, renewable energy sources such as geothermal, wind, and solar, critical minerals such as rare earth elements, and to address the environmental impacts of uranium mining.
Specifically, the budget includes a program increase of $1 million for mineral resources science to continue life-cycle analysis for critical minerals such as rare earth elements and to develop new science and tools to reduce the impacts of minerals extraction, production, and recycling on the global environment and human health. A life-cycle analysis will trace the flow of critical minerals from generation and occurrence through the consequences of human activity to ultimate disposition and disposal. The Nation faces key economic decisions within each stage of the resource life cycle. Scientific understanding is an essential input to these decisions. The program change will support new workforce capability to address the main thrusts of the President’s four working groups in the Office of Science and Technology Policy that are currently focused on critical and strategic materials essential to national security, economic vitality, and environmental protection.
Responding to Natural Hazards
The budget provides an increase of more than $6.6 million above the FY 2015 enacted level for natural hazard science. This includes an increase of $4.9 million to expand the Global Seismic Network used for worldwide earthquake monitoring, tsunami warning, and nuclear treaty verification monitoring and research in partnership with the Department of Energy and the Department of Defense. It also includes a $1.7 million increase to support space weather (solar flare) geomagnetic monitoring. The increase will also support the installation and operation of rapid-deployable streamgages and expand the library of flood-inundation maps to help manage flood response activities. The proposed increase will also support landslide, wildfire, and sinkhole response capabilities as well as provide disaster scenario planning products for emergency managers. Included in the request is funding to build on investments to continue development of an earthquake early warning system, with the goal of implementing a limited public warning system for the U.S. west coast by 2018, as well as continued investments in volcano monitoring networks and science.
Building a Landscape-Level Understanding of Our Resources
The budget includes $15.6 million to expand, enhance, and initiate ecosystem science activities to increase the understanding of the Nation’s landscapes and how they work. This includes budget increases of $6.7 million in support of critical landscapes. Specifically it provides a $4.2 million increase for the Arctic, a $1 million increase to study sagebrush landscapes that provide habitat for survival of greater sage-grouse, and a $1.5 million increase that supports science for Puget Sound, Columbia River, and the upper Mississippi River. USGS research will continue to support restoration of other priority ecosystems, such as Chesapeake Bay, Everglades, Great Lakes, California Bay Delta, and the Gulf Coast. The budget request also provides an increase of $2.2 million for research on invasive plants and animals that cause significant economic losses in the U.S. and transmit diseases to wildlife and people, and $1.6 million to study the decline of insects, birds, and mammals that pollinate agricultural and other plants. Finally, the budget increases funding by $5.1 million to support coastal resilience to hazards and adaptation to long-term change from sea-level rise and coastal erosion.
Foundations for Land Management
The President’s budget request includes an increase of $37.8 million to provide data and tools to help land and resource managers make informed decisions across the landscape and provide data and information to the public for use in a wide variety of applications. The budgets of USGS and NASA provide complementary funding to sustain the Landsat data stream, which is critical to understanding global landscapes. An increase of $24.3 million in the USGS budget supports the ground system portion of the Sustained Land Imaging Program, including funding for ground systems development for a Thermal Instrument Free Flyer, Landsat 9 (a rebuild of Landsat 8), and to receive data from internal partners. The increase also will enhance the accessibility and usability of data. Specifically, the budget includes a $4 million increase for Landsat science products for climate and resource assessments.
The budget provides increases for other foundational data and tools needed to support landscape-level understanding. For example, an increase of $3.7 million will expand three-dimensional elevation data collection using ifsar (interferometric synthetic aperture radar) for Alaska and lidar (light detection and ranging) elsewhere in the U.S. in response to growing needs for high-quality, high-resolution elevation data to improve aviation safety, to understand and mitigate the effects of coastal erosion, storms, and other hazards, and to support many other critical activities. A $1.8 million increase will enhance understanding of the benefits of the Nation’s ecosystem services, and a $1.1 million increase for the Big Earth Data Initiative will make high-value data sets easier to discover, access and use. The accessibility and usability of these data are critical for land management, hazard mitigation, and building a landscape-level understanding of our resources.
Supporting Community Resilience in the Face of a Changing Climate
The USGS plays an important role in conducting research and developing information and tools to support communities in understanding, preparing for, and responding to the impacts of global change. The budget includes an increase of $32 million above the FY 2015 enacted level for science to support climate resilience and adaptation. Climate change requires the Nation to prepare for more intense drought, heatwaves, wildfire, flooding, and sea level rise. These challenges are already impacting infrastructure, food and water supplies, and physical safety in communities across the Nation. Understanding potential impacts to communities, ecosystems, water, plant and animal species, and other resources is crucial to federal, state, tribal, local, and international partners as they develop adaptive and resilient strategies in response to climate change. The budget includes a $6.8 million increase in science for adaptation and resilience planning, an increase of $2.3 million for the USGS to provide interagency coordination of regional climate science activities across the Nation, an increase of $8.7 million to support biological carbon sequestration, and an increase of $11 million for the USGS to support the community resilience toolkit, which is a web-based clearinghouse of data, tools, shared applications, and best practices for resource managers, decision-makers, and the public.

New and improved science tools can help managers and researchers evaluate current threats and develop management strategies to protect and restore the valuable Great Lakes ecosystem.
The recently released U.S. Geological Survey products provide free environmental data to the public as part of the Great Lakes Restoration Initiative (GLRI), a collaborative effort to conserve the Great Lakes. The new GLRI Science Explorer and redesigned GLRI website (most compatible with the Google Chrome browser*), launched in November 2014, offer critical information pertaining to USGS GLRI projects, and allow researchers to contribute their own material. The interactive Science in the Great Lakes (SiGL) mapper was released in December 2014 and provides information about current and past Great Lakes studies.
Researchers, managers and the public can use the GLRI Science Explorer to find information about USGS GLRI science projects, as well as publications and datasets resulting from those projects. It currently contains information about 74 projects that are completed and in progress, 66 publications and 11 datasets. Science Explorer information is stored in ScienceBase, a cataloging and content management platform developed by the USGS, which allows for contributions from USGS scientists and collaborators.
“We are eagerly seeking contributions of data or metadata to the Science Explorer,” said USGS scientist Jessica Lucido.
The interactive SiGL mapper is a centralized place where researchers and managers can identify relevant scientific activities and access fundamental information about these efforts. It was designed to help coordinate all of the scientific projects in the Great Lakes Basin. SiGL captures information about any type of scientific activity and provides details on how to access the data and results from those projects.
“SiGL can help researchers and managers strategically plan, implement and analyze their monitoring and restoration activities,” said Jennifer Bruce, a USGS scientist. “We hope to encourage coordination and collaboration among all organizations throughout the Great Lakes Basin with this tool.”
SiGL contains over 250 projects and 10,500 sites, including all the USGS GLRI projects in the Science Explorer. Over 65 organizations have contributed to SiGL, including federal, state and local governments and agencies, tribes, universities and non-profit organizations. It provides information about general project details, specific sampling efforts, publications, data availability and access and contact information.

The estimated value of mineral production increased in the United States in 2014, despite the decline in price for most precious metals, the U.S. Geological Survey announced today in its Mineral Commodity Summaries 2015.
The estimated value of mineral raw materials produced at mines in the United States in 2014 was $77.6 billion, an increase of 4.6 percent from $74.2 billion in 2013. U.S. economic growth supported the domestic primary metals industry and industrial minerals industry, however, weak global economic growth and the strong U.S. dollar limited U.S. processed mineral exports, which decreased to $108 billion in 2014 from $129 billion in 2013. Meanwhile, low-priced metal imports increased during most of 2014.
The annual report from the USGS is the earliest comprehensive source of 2014 mineral production data for the world. It includes statistics on about 90 mineral commodities essential to the U.S. economy and national security, and addresses events, trends, and issues in the domestic and international minerals industries.
"Decision-makers and policy-makers in the private and public sectors rely on the Mineral Commodity Summaries and other USGS minerals information publications as unbiased sources of information to make business decisions and national policy," said Steven M. Fortier, Director of the USGS National Minerals Information Center.
Mineral commodities remain an essential part of the U.S. economy, contributing to the real gross domestic product at several levels, including mining, processing and manufacturing finished products. The United States continues to rely on foreign sources for raw and processed mineral materials. In 2014, the supply for more than one-half of U.S. apparent consumption of 43 mineral commodities came from imports, increasing from 40 commodities in 2013. The United States was 100 percent import reliant for 19 of those commodities, including indium, niobium, and tantalum, which are among a suite of materials often designated as “critical” or “strategic.”
Mine production of 13 mineral commodities was worth more than $1 billion each in the United States in 2014. These were, in decreasing order of value, crushed stone, copper, gold, cement, construction sand and gravel, iron ore (shipped), industrial sand and gravel, molybdenum concentrates, phosphate rock, lime, salt, zinc, soda ash, and clays (all types). The estimated value of U.S. industrial minerals mine production in 2014 was $46.1 billion, about 7 percent more than that of 2013.
The estimated value of U.S. metal mine production in 2014 was $31.5 billion, slightly less than that of 2013. These raw materials and domestically recycled materials were used to process mineral materials worth $697 billion. These mineral materials, including aluminum, brick, copper, fertilizers, and steel, plus net imports of processed materials (worth about $41 billion) were, in turn, consumed by industries that use minerals to create products, with a value added to the U.S. economy of an estimated $2.5 trillion in 2014.
The construction industry continued to show signs of improvement in 2014, being led by nonresidential construction, with increased production and consumption of cement, construction sand and gravel, crushed stone, and gypsum mineral commodities.
In 2014, 12 states each produced more than $2 billion worth of nonfuel mineral commodities. These states were, in descending order of value—Arizona, Nevada, Minnesota, Texas, Utah, California, Alaska, Florida, Missouri, Michigan, Wyoming and Colorado. The mineral production of these states accounted for 62 percent of the U.S. total output value.
The USGS Mineral Resources Program delivers unbiased science and information to understand mineral resource potential, production, consumption, and how minerals interact with the environment. The USGS National Minerals Information Center collects, analyzes, and disseminates current information on the supply of and the demand for minerals and materials in the United States and about 180 other countries.
The USGS report Mineral Commodity Summaries 2015 is available online. Hardcopies will be available later in the year from the Government Printing Office, Superintendent of Documents. For ordering information, please call (202) 512-1800 or (866) 512-1800 or go online.
