Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown.
USGS Current Conditions for Kansas: Build Current Table

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
** 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.
