Unified Interior Regions
South Dakota
Surface water and groundwater provide important water supplies in South Dakota. Major rivers include the Big Sioux, James, Cheyenne, and Missouri Rivers. Key aquifers include the Dakota, Madison, Minnelusa, and Big Sioux aquifers. The Dakota Water Science Center has many studies that focus on these resources as well various other national and international studies.

Natural Drought and Flood Histories from Lacustrine Archives
Previous work performed as part of the USGS Holocene Synthesis project illuminated complex centennial-scale patterns of drought and wetter-than-average conditions across the North American continent interior during the past two millennia, where paleorecord data coverage is sparse. In order to explain the patterns of naturally-occurring drought, floods, and storms for the past, identified by...
EROS User Group
The purpose of the EROS User Group (EUG) is three-fold:
- Provide operational users of EROS products and services with an opportunity and platform to discuss opinions, needs, and concerns in a structured and consistent manner;
- Provide EROS projects with a consistent platform for targeted communications and opportunity for direct feedback from the user community on product- ...
Williston Basin Oil and Gas Assessments
The U.S. Geological Survey completed the following assessments of conventional and continuous oil and gas resources of the Devonian Three Forks Formation and Devonian and Mississippian Bakken Formation in the Williston Basin Province 5031 of North Dakota, Montana, and South Dakota.
Remote Sensing Phenology
Phenology is the study of plant and animal life cycles in relation to the seasons. EROS maintains a set of nine annual phenological metrics for the conterminous United States, all curated from satellite data. Taken together, the metrics represent a powerful tool for documenting life cycle trends and the impacts of climate change on ecosystems.
Land Cover Projections
Scientists at EROS look at local and global drivers of land-use change to project how different scenarios will impact and change landscapes. Using the FOREcasting SCEnarios of Land-use Change (FORE-SCE) modeling framework provides spatially explicit projections of future land-use and land-cover change.
Coastal National Elevation Database (CoNED) Applications
The Coastal National Elevation Database (CoNED) and Applications project at EROS offers information used for a range of applications analysis needed for climate change analysis.
Land Treatment Exploration Tool
The Land Treatment ExplorationTool provides a practical resource for managers who are planning restoration and rehabilitation actions on public lands. The tool generates a variety of spatial products while being user friendly for all levels of GIS expertise, even to those with little or no experience.
Bird Banding Laboratory
The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America. This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...
Williston and Powder River Basins Groundwater Availability Study
The development of two nationally important energy-producing areas, the Williston structural basin (containing the Bakken Formation) and Powder River structural basin, provide a critical opportunity to study the water-energy nexus within a groundwater context. Large volumes of water are needed for energy development in these basins. The hydraulically connected aquifers in the...

Eyes on Earth Episode 2 - Chernobyl
When an accident occurred at the Chernobyl Nuclear Power Plant's No. 4 reactor in Ukraine on April 26, 1986, Landsat satellites were among the first to capture visual evidence of its widespread impact. This episode of Eyes on Earth outlines how the disaster focused the world's attention on the value of remote sensing.
Eyes on Earth - Episode 3 - The National Land Cover Database
Sorting Landsat data into an accurate and reliable record of land cover in the United States is one of the most important jobs at EROS. This episode of Eyes on Earth explores the what, how, and why of the National Land Cover Database (NLCD).
Eyes on Earth Episode 5 – Declassified Data at EROS
There’s a lot more than Landsat in the EROS Archive. In this episode of Eyes on Earth, we hear from a professor who’s mined satellite data collected during once-classified military missions to peer into the history of land use in Eastern Europe during the height of the Cold War.
Image of the Week - 50 Year Flood Flashback
A Landsat satellite image captured the flooding in Dell Rapids, SD in the Spring of 2019. It's remarkably similar to an aerial photograph of flooding 50 years earlier.
Eyes on Earth Episode 1 - Intro to EROS
A rundown of the history of the USGS Earth Resources Observation and Science (EROS) Center, the Landsat program, and the Center's role in the observation and study of landscape change worldwide.
Eyes on Earth Episode 8 – Assessing America’s Cropland
Every year, the USDA’s National Agricultural Statistics Service (NASS) uses data from satellites like Landsat to estimate crop types and crop yields in the United States. The result is the Cropland Data Layer (CDL), which offers an annual look at more than 100 crop categories across the country. In this episode, Dave Johnson with NASS discusses how Landsat can identify
Image of the Week - A New Yellowstone Hot Spot
Scientists with the USGS Yellowstone Volcano Observatory use satellite and aerial imagery to map hot springs, geothermal vents, and geysers at Yellowstone National Park. They recently found an entirely new thermal area miles from the nearest trailhead. Landsat 8's thermal infrared sensors captured the change in a nighttime image from April of 2017. Aerial images reveal a
Variable Warming Upper Midwest Lakes and Implications for Sport Fish
Climate change is predicted to alter sport fish communities in Midwestern lakes, but managers currently have limited information on individual lakes that can be used to set local expectations or intervene with mitigation strategies. Northeast and North Central CASC supported researchers, with strong participation from the Midwest Glacial Lakes Partnership, have combined

Members of the LANDFIRE team met in March of 2019 at the USGS Earth Resources Observation and Science (EROS) Center near Sioux Falls, SD.
Winter Streamflow Measurement at South Fork Grand River near Cash, SD
USGS Hydrologic technician Sarah Davis measuring streamflow at the South Fork Grand River near Cash, SD (streamgage 06356500) on January 31, 2019. Measuring the streamflow under ice requires drilling holes across the width of the stream and then collecting data from each hole. At times streams can freeze solid but drilling holes are necessary to verify that. The

Reporters: Do you want to interview USGS scientists in the Sioux Falls area on Monday, March 25, or Tuesday, March 26, as they measure flooding? Please contact Jennifer LaVista, Marisa Lubeck or Chris Laveau.
Will oversee Landsat satellite and Earth imaging operations

The mapping and classification of land use and land cover has long been a primary duty for the U.S. Geological Survey (USGS), and remotely-sensed data at the Earth Resources Observation and Science (EROS) Center has served as the backbone of the Survey’s modern efforts.
In recent years, two advancements in remote sensing emerged that promise to revolutionize the field.

Agencies like NASA and the U.S. Geological Survey (USGS) that commit multiple millions of dollars to put Landsat satellites into space need to know that the spacecraft, the sensors onboard, the ground system operating the satellite, and the launch vehicle are all designed and built the right way.

Tim Rykowski has a history of reviewing satellite ground systems. NASA’s Space Network Systems Manager, Rykowski figures he’s probably sat in on a few dozen such reviews during his 35 years at NASA, including the design and build of the Landsat 9 (L9) Ground System that’s going on now.
When they step out of their science or engineering realms, staff members at the Earth Resources Observation and Science (EROS) Center near Sioux Falls, SD, often tell a different story about the work they do.
In many ways, a more interesting story.
