    The effect of flood is very adverse to living organism and surrounding nature, so that it is noteworthy to study the characteristic of peak flood viewed from its change and the capability of River Flow Area (DAS) in dealing with stormy rain. Because the Keduang river flow enters Wonogiri reservoir, this river is chosen to make the flood disaster controlling in Solo area runs smoothly. This research used Nakayasu method. The data needed was the data of rainfall for 1999-2000 period viewed from repeated term flow rate compared with the 2-days annually and monthly flood flow rates so that the potential flood can be detected. In writing this final project, the result of data and calculation of flood flow rate based on the repeated terms 2, 5, 10, 20, 50, 100, 200, 1000 were as follows: 388.856 m3/s, 541.874 m3/s, 690.347 m3/s, 851.048 m3/s, 1195.229 m3/s, 1509.666 m3/s, 1904.774 m3/s, and 3254.336 m3/s. The potential annual flood based on 2-days maximum annual rain in 1999-2002, 2006, 2008, 2008, 2009 and 2011 potentially experienced flood Q2, in 2003-2005 and 2007 Q5 and in 2010 Q10. The monthly flood potential based on 2-days maximum monthly rain during 1999-2011 period was Q2 on January-March, June and September-October, Q5 on November, and Q10 on December. Keywords : repeated period flood flow rate, flood potential
