"As part of the U.S. Geological Survey's (USGS) program for disseminating water data within USGS, to USGS cooperators, and to the general public, the USGS maintains a distributed network of computers and fileservers for the acquisition, processing, review, and long-term storage of water data. This water data is collected at over 1.5 million sites around the country and at some border and territorial sites. This distributed network of computers is called the National Water Information System (NWIS). Many types of data are stored in NWIS, including comprehensive information for site characteristics, well-construction details, time-series data for gage height, streamflow, ground-water level, precipitation, and physical and chemical properties of water. Additionally, peak flows, chemical analyses for discrete samples of water, sediment, and biological media are accessible within NWIS.
"NWISWeb is the USGS public web interface to much of the data stored and managed within NWIS. Data provided by NWISWeb are updated from NWIS on a regularly scheduled basis, and real-time data are generally updated upon receipt at local Water Science Centers. NWISWeb provides several output options including: graphs of real-time streamflow, water levels, and water quality; tabular output in HTML and ASCII tab-delimited files; and summary lists for selected sites that can be used as a basis for reselection to acquire refined details.
"NWISWeb provides a framework to obtain data on the basis of category, such as surface water, ground water, or water quality, and by geographic area. Further refinement is possible by choosing specific site-selection criteria and by defining the output desired. In addition, there are nearly 70 million water-quality results from nearly 4.5 million water samples collected at hundreds of thousands of sites."
The U.S. Geological Survey, in cooperation with the Indiana Department of Natural Resources has collected ground-water data in Indiana since 1935. Today, the state observation well network consists of 37 active wells located throughout the state. Nine of these observation wells have been selected for monitoring, one in each climate division, to represent the general ground-water condition throughout the state.
The IDNR, Division of Water analysis can be accessed through their Web site: Indiana Department of Natural Resources, 2008, Status of ground water levels: Indiana Department of Natural Resources, Division of Water Web site, <http://www.in.gov/dnr/water/7138.htm>, date accessed, September 4, 2008.
Data from all 37 observation wells are collected in the field periodically by USGS personnel, checked for accuracy, and entered into a computerized database. The data are then downloaded by IDNR, Division of Water, graphed and analyzed.
A primary purpose of monitoring ground-water levels in the state is to monitor drought severity. Additional information on drought severity can be obtained through the following IDNR Web sites:

"Real-time data are time-series (recorded at fixed intervals) data from automated equipment and represent the most current hydrologic conditions. Measurements are commonly recorded at 5-60 minute intervals and transmitted to the NWIS database every 1-4 hours. Real-time data are available online for 31 days.
"Daily values are summarized from time-series data for each day for the period of record and may represent the daily mean, median, maximum, minimum, and/or other derived value. Daily values include approved, quality-assured data that may be published, and more recent provisional data, whose accuracy has not been verified.
"Manual measurements of depth to water in wells. These measurements are often used to supplement and (or) verify the accuracy of the instantaneous measurements."
