Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified. Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data. Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.

|Site identification number
Each site in the USGS data base has a unique 8- to 15-digit identification number.
This is the official name of the site in the database. For well information this can be a district-assigned local number.

A list of primary and secondary site types that can be associated with data collection sites. A site type is a generalized location in the hydrologic cycle, or a man-made feature thought to affect the hydrologic conditions measured at a site. All sites are associated with a primary site type, and may additionally be associated with a secondary site type that further describes the location. The exception to this rule is the Facility primary site type, which must always be associated with a secondary site type. The site type code incorporates these hierarchial distinctions.
"A body of running water moving under gravity flow in a defined channel. The channel may be entirely natural, or altered by engineering practices through straightening, dredging, and (or) lining. An entirely artificial channel should be qualified with the ""canal"" or ""ditch"" secondary site type."

The Water Science Centers (WSCs) across the United States use the FIPS state code as the district code. In some case, sites and samples may be managed by a water science center that is adjacent to the state in which the site actually resides.
The name of the state or territory in which the site is located.
The name of the county or county equivalent (parish, borough, etc.) in which the site is located.

|Subbasin hydrologic unit
Hydrologic units are geographic areas representing part or all of a surface drainage basin or distinct hydrologic feature and are delineated on the State Hydrologic Unit Maps.
The Basin Code or "drainage basin code" is a two-digit code that further subdivides the 8-digit hydrologic-unit code.
Refers to the geomorphic features in the vicinity of the site.
