You can always try the River Forecast Center: http://www.erh.noaa.gov/er/ohrfc/
Down at Louisville: http://www.crh.noaa.gov/ahps2/hydrograph.php?wfo=lmk&gage=mluk2
Hope those help.

Those sites, along with every other site that I could find, only give the "Volume" of water or the Cubic Feet per second. Which can not be converted into "MPH". But thanks for the info.
