Kentucky

Version 3 is now available for all states

StreamStats version 3 is now available for all states. Version 2 has been retired. Currently, version 3 can only delineate drainage basins, compute basin characteristics, and estimate streamflow statistics using regression equations for user-selected sites. It also can provide reports of information for USGS data-collection stations. All other functionality that previously was available in version 2 will be added to version 3 as quickly as possible, with a goal of having all functionality available by the end of 2015.

Please help us conserve our server system resources by closing the Interactive Map window when you are finished using it. Doing so will help ensure system availability for all users. Thank you.

Also, please bookmark this page rather than the Interactive Map page, as the URL for the interactive map may change in the future.

Kentucky StreamStats incorporates regression equations for estimating instantaneous peak flows with annual exceedance probabilities of 50, 20, 10, 4, 2, 1, 0.5, and 0.2 percent. These peak flows have recurrence intervals of 2, 5, 10, 25, 50, 100, 200, and 500 years, respectively. The report below documents the regression equations available in StreamStats for Kentucky, the methods used to develop the equations and to measure the basin characteristics used in the equations, and the errors associated with the estimates obtained from the equations. Users should familiarize themselves with this report before using StreamStats to obtain estimates of peak flows for ungaged sites.

The peak-flow regression equations are implemented only for hydrologic regions 2, 3, 5, 6, and 7 in Kentucky. Drainage area is the only explanatory variable in these equations. Equations for hydrologic regions 1 and 4 are not implemented at this time because an additional explanatory variable, stream slope, is needed to solve the equations. The capability for StreamStats to compute stream slope in a manner that duplicates the method used in the report by Hodgkins and Martin (2003) has not yet been devised.
