USGS Water Science Centers are located in each state.
Water Resources of South Dakota
Welcome to the USGS Web page for water resources in South Dakota. Here, you will find information on South Dakota's rivers and streams. You will also find information
on groundwater, water quality, and many other topics. The USGS operates the most extensive satellite network of streamgages in South Dakota, many of which form
the backbone of flood-warning systems.
Groundwater and Drought: Groundwater is among the Nation's most important natural resources. It provides half our drinking water and is essential to the vitality of agriculture and industry, as well as to the health of rivers, wetlands, and estuaries throughout the country. Droughts can significantly impact the Nation's groundwater resources while the drought is occurring and for some time afterward. Understanding groundwater, surface water, and the integrated nature of the hydrologic system enables resource managers and policy makers to better prepare for and respond to drought. The USGS provides groundwater data and information that resource managers and policy makers can use to prepare for and respond to drought.
StreamStats for South Dakota: StreamStats is a Web-based Geographic Information System (GIS) that provides users with access to an assortment of analytical tools that are useful for water-resources planning and management, and for engineering design applications, such as the design of bridges. StreamStats allows users to easily obtain streamflow statistics, drainage-basin characteristics, and other information for user-selected sites on streams. StreamStats users can choose locations of interest from an interactive map and obtain information for these locations. Separate applications have been established for each State that has implemented StreamStats, such as South Dakota.
NWIS Mapper: Are you looking for a new way to access water data? This interface provides a map view of the locations of sites with USGS water data. Simply zoom into your area of interest, select your site types using the checkboxes provided, and click on your site.

Black Hills Area Floods Since 1877
The U.S. Geological Survey (USGS), National Weather Service, and the South Dakota Department of Transportation have cooperated on compiling a chronology of flood events in the Black Hills area that have occurred since 1877. The Black Hills area of western South Dakota has a history of damaging flash floods that have resulted primarily from exceptionally strong rain-producing thunderstorms, such as the 1972 flood that claimed the lives of 238 people and the more recent 2007 flood in the Hermosa area. Many other notable floods have occurred in the Black Hills area since settlement of the Black Hills in the late 1800s. These notable floods include the 1883 flood in Deadwood, the 1907 flood in the Piedmont area, the 1924 flood in the Belle Fourche area, and the 1937 flood in the Hot Springs area. The project Web site provides the chronology of flood events that are documented in some way since 1877 in newspapers, books, photographs, and technical reports.
The purpose of the flood compilation is to provide documentation and a context for the frequency and relative magnitude of historical large floods in the Black Hills area. The improved knowledge of flooding in the Black Hills area will be used to aid in the application of paleoflood survey techniques that is being performed by the USGS in cooperation with the South Dakota Department of Transportation.

The report "Conceptual and Numerical Models of Groundwater Flow in the Ogallala and Arikaree Aquifers, Pine Ridge Indian Reservation Area, South Dakota, Water Years 1980-2009" was completed in cooperation with the Oglala Sioux Tribe. This report describes the conceptual and numerical models of groundwater flow in the Ogallala and Arikaree aquifers in the Pine Ridge Reservation area. The models were based on hydrologic data for water years 1980-2009. Steady-state and transient numerical simulations for the 30-year period are described in this report. This report also documents numerical simulation of two potential future scenarios. The first scenario represented an increase in groundwater withdrawals from 50 hypothetical production wells, and the second scenario represented a potential 30-year period of decreased recharge (drought). The report is available at http://pubs.usgs.gov/sir/2014/5241/.

Microgravity Research at the Sanford Underground Research Facility
This video of microgravity field work at the Sanford Underground Research Facility in Lead, SD, was filmed at the 4,850-foot level (about 4,850 feet underground) on August 27, 2014, by Jeff Kennedy of the USGS Arizona Water Science Center.
The second video of microgravity field work at the Sanford Underground Research Facility in Lead, SD, was filmed at the 300-foot level (about 300 feet underground) by Jeff Kennedy of the USGS Arizona Water Science Center. The microgravity research, in its fifth year, is being done in collaboration with the USGS South Dakota Water Science Center to monitor the dewatering of the underground facility.
