SYSTEM NOTICE: Friday, February 10, 2012, through Sunday February 12, 2012 there will be a planned power outage in one of our USGS facilities. This should not affect the availability of any data that we serve; however, the mapping interface which displays sites on a map will be unavailable. A follow-up notice will be sent when the power is fully restored. All real-time current data will continue to be available at http://waterdata.usgs.gov/nwis.

(1,565,966 sites)

Information for each site in the USGS data base can be retrieved for viewing and for download and import into other software, including GIS software. Includes links to all water data available for individual sites.

Introduction

The Site Inventory System contains and provides access to inventory information about sites at stream reaches, wells, test holes, springs, tunnels, drains, lakes, reservoirs, ponds, excavations, and water-use facilities.

About 300 components make up the descriptive elements of the site inventory. The retrieval program can be used for retrieving information about sites in summary lists, in detailed tables, or a file suitable for input to other programs.
