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.

Derivation of homogeneous streamflow records in the upper Kentucky River basin, southeastern Kentucky
Decisions regarding municipal water supply and additional reservoir construction in the Kentucky River basin dictate the need for increased knowledge of Kentucky Diver low-flow characteristics. Digital computer programs were developed ta route streamflow through reservoir and stream reach components of a stream system. Using these programs as submodels, with availatle observed data, and utilizing appropriate data-handlinq techniques, a digital model of the Upper Kentucky River basin was developed. This model was specifically used to simulate streamflow data which would be adequate to determine the characteristics at tock 10 on the Kentucky River near Winchester, low-flow Kentucky for thirty-one years of regulated conditions. Model inputs consisted of (1) operation criteria for an existing reservoir; reservoir and (2) observed streamflow data for twenty-one years of natural and ten years of:regulated These conditions. techniques are also suitable for studying alternative modeling streamflow requlation schemes and expanding networks of homogeneous streamflow data for regional analyses.
