Low-flow characteristics of Kentucky streams - A preliminary report

The U.S. Geological Survey has been gathering low-flow data on streams throughout Kentucky for several decades. Much of the data now have been analyzed to determine the frequency of the annual low flow on those streams. Knowledge of the magnitude and frequency of low flow is necessary for planning, managing, and protecting water resources of the Commonwealth. Some specific uses are to analyze potential water-supply capacity, for control of water quality, and for the management of recreation potential. 

This preliminary report presents a low-flow characteristic at each site where defined, and where the flow is not significantly regulated. That characteristic, the 7-day, 10-year low flow, is the one which seems to be most in demand because of its use in water quality planning and control.
