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.

Landsat in Action - Changing Forest Phenology with Andrew Elmore
When parking lots go up, when rooftops multiply, land cover and land uses change. Professor Andrew Elmore with the University of Maryland’s Center for Environmental Science understands that very well, and explains how he uses Landsat to study and quantify that change in USGS EROS’ latest “Landsat in Action” video conversation. Elmore delves into the changing phenology of

Every Pixel - Landsat's Orbit
Ever wonder how Landsat 8 orbits our planet? Here is an overview to explain this part of how we capture every pixel.
Every Pixel - Landsat's Sensors
On board Landsat 8 are two sensors that capture data about earth's surface. Here is an explanation of the instruments that capture every pixel.
Every Pixel - Recording Data
Recording every pixel as Landsat orbits Earth is a complicated task. Here is an overview of how that data goes from the sensors into the recorder.

Low-Flow Streamflow Measurement at Little Missouri River
Hydrologic technician Sarah Davis measured low-flow discharge at USGS streamgage 06334500, Little Missouri River near Camp Crook, SD (https://waterdata.usgs.gov/sd/nwis/inventory/?site_no=06334500&agency_cd=USGS&) on November 16, 2017.
...Landsat Analysis Ready Data (ARD)
The U.S. Geological Survey (USGS) has improved Landsat data quality and usability through the creation of Analysis Ready Data (ARD) for the conterminous United States, Alaska, and Hawaii. Landsat ARD greatly reduces the preparatory work currently required to do time-series analysis for understanding landscape change for operational and science users. Landsat Collections
LGSOWG #46 - Invitiation to Rapid City
LGSOWG #46 was held in Rapid City, South Dakota in 2017.
Choosing a Data Access Tool: AppEEARS Area Sampler
This video focuses on the Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) Area Sampler. With AρρEEARS, users can retrieve analysis ready data for specific areas of interest for a variety of NASA data products, including those derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard NASA’s Terra and Aqua satellites. AρρEEARS
EROS Phenocam
A screenshot of the phenocam at the U.S. Geological Survey Earth Resources Observation and Science (EROS) Center near Sioux Falls, SD. EROS established a near-ground automated digital camera in 2014 and joined over 100 other core sites in the PhenoCam Network. Following the protocols of the network, the EROS camera
...Landsat Collections — What are Tiers?
This is the third video in a series describing the new U.S. Geological Survey (USGS) Landsat Collection 1 inventory structure. Collection 1 required the reprocessing of all archived Landsat data to achieve radiometric and geometric consistency of Level-1 products through time and across all Landsat sensors. This video explains how Landsat Collection Level-1 data products
Streamflow of the Moreau River near Whitehorse, SD set a new record high when the water level peaked on Sunday, March 20, according to real-time U.S. Geological Survey streamgage data.
Record-breaking floods are possible in various locations in South Dakota this spring, and the public can track flood levels throughout South Dakota using the U.S. Geological Survey’s FloodWatch webpage.
Regional flood and storm potentials are highest along the eastern and northeastern periphery of the Black Hills and generally include the areas from Hot Springs to Spearfish, according to a recent report by the U.S. Geological Survey.
Everyday, high above the clouds, dozens of sophisticated imaging satellites circle the Earth, capturing extraordinary conditions and events that are nearly impossible to document from the surface of the planet. These images reveal the planet's surface through the "eyes" of a space satellite.
In this USGS media tipsheet, we've gone through thousands of GSA conference abstracts and selected some of the newest, most exciting USGS science presentations for your convenience. We hope you find it useful.
Heavy rainfall of up to 10 inches in South Dakota has caused record flooding in Firesteel Creek and Sand Creek in the eastern part of the state.
Greater sage-grouse populations have declined substantially in many areas in the West, though populations in some locations remain relatively stable, according to a comprehensive publication written by federal, state, and non-governmental organizations. The population assessment is one of numerous sage-grouse topics covered in the 24 chapters released today.
Levels of chloride, a component of salt, are elevated in many urban streams and groundwater across the northern U.S., according to a new government study. Chloride levels above the recommended federal criteria set to protect aquatic life were found in more than 40 percent of urban streams tested. The study was released today by the U.S. Geological Survey (USGS).
Water produced by the High Plains aquifer, which provides water to eight states, is generally acceptable for human consumption, irrigation, and livestock watering, according to a U.S. Geological Survey study highlighted at the summer meeting of the Western States Water Council in Park City, Utah.
New visual representations of South American terrain will be freely available on the web as the most complete database of its kind.
Dr. Thomas Loveland, Senior Scientist at the U.S. Geological Survey's (USGS) Earth Resources Observation and Science (EROS) Center has been named a 2009 Fellow for the American Society for Remote Sensing and Photogrammetry. Annually, one or two professionals are awarded the fellowship for exceptional service in advancing science and the mapping sciences.
Striking new glacier retreat photographs created by the U.S. Geological Survey (USGS) visually illustrate the effects of climate change on Glacier National Park.
The glacier images reveal dramatic glacial decline over a century and are in line with predictions that all of the glaciers in Glacier National Park will disappear by 2030.
