Flow duration of Kentucky streams through 1990; historical and monthly flow characteristics, including the effects of reservoirs

January 1, 1995

This report presents flow-duration tables and plots for selected streamflow sites in Kentucky with three or more years of continuous record through 1990. Flow duration describes the frequency with which given streamflows are equalled or exceeded. The flow-duration tables were computed using daily mean discharge values for the entire period specified and for each month of the period specified. Only complete years of record were used for the computation. For sites where the streamflow is affected by regulation, separate tables are presented for the period before regulation (unregulated), the period of record after regulation (regulated) and the entire period of record (historical). Flow-duration plots are also presented for each station using the data for the entire period specified. Where practicable, several flow-duration plots are shown together. This includes stations on the same stream, such as main-stem stations, and stations within the same watershed. For stations affected by regulation, which have up to three sets of data available for one station (unregulated, regulated, and historical), the three plots are shown together to clearly illustrate the influence of regulation in augmenting low flows and reducing high flows.
