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.



The statistics generated from this site are based on approved daily-mean data and may not match those published by the USGS in official publications. The user is responsible for assessment and use of statistics from this site. For more details on why the statistics may not match, click here.
