USGS Water Data for Kansas

Click to hide state-specific text

*** The Kansas Water Science Center has transitioned to a new data management software package. While you may not have noticed this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible. See the Dec 8 news entry for more information at: https://help.waterdata.usgs.gov/news
Historic (pre-2007) gage-height data may contain erroneous values, such as pressure sensors encased in ice, even if they are flagged as approved. These data are made available to the public, but data users are cautioned to carefully screen the data and contact the USGS Kansas Water Science Center if they have questions or concerns about specific values.

** During winter months the realtime streamflow displayed may not reflect the true discharge for periods when ice forms in the stream. When ice forms, the river cross-section is constricted and produces a higher river stage for any given amount of discharge that exists during ice-free periods. This condition is known as backwater. Although accurate themselves, the river stages can no longer be used to accurately and directly compute discharge from the rating curve (which relates stage to discharge) because the amount of backwater varies with time, temperature, and other factors. More complex procedures that require the use of meteorological and hydrological data from other stations in the area must be used to determine discharge at the affected stations. Unfortunately, these more complex procedures cannot yet be applied in real time. Additional, ice forming in the channel can result in erroneous readings as the instrumentation in the stream is adversely affected by the ice generally resulting in an erroneously higher stage reading. While every attempt is made to screen erroneous data from the realtime display, this data is considered provisional and should be used with caution.

Introduction

The U.S. Geological Survey's (USGS) National Water Information System (NWIS) is a comprehensive and distributed application that supports the acquisition, processing, and long-term storage of water data. USGS Water Data for the Nation Site serves as the publicly available portal to a geographically seamless set of much of the water data maintained within NWIS (additional background).

USGS Water Data for the Nation Site provides access to water data from over 1.5 million sites in all 50 States and additional border and territorial sites. The data are organized within the categories listed to the left.

The water data available via this site have been acquired as part of the USGS investigations of the occurrence, quantity, quality, distribution, and movement of the surface and underground waters that constitute the Nation's water resources. Additional information about the USGS and water resources of the Nation is available at water.usgs.gov.
