The <br />irregular distribution of floods on the Little Pigeon River is illustrated <br />by the following data: The three greatest known floods (1867,1875, <br />and 1896) occurred in the 19th century. Since1921 the four floods that <br />had stages within 2 feet of the 1965 crest occurred in the preceding 9 <br />years, <br />Peak stages were determined at one gaging station and at five crest- <br />stage partial-record stations.

H. :H..A.NNUM <br /> <br />Most'of the March rainfall in western Kentucky fell in 'two storms <br />that passed over the irea between March 24 and March 29. The first <br />storm of 2-day duration, March 25-26, caused little or no flooding, but <br />it established antecedent conditions for the second storm, The second <br />storm was of I-day duration, and rainfall ranged from 1.6 to 5.6 inches <br />over the area. Severe flooding occurred - on some streams in the storm <br />area (fig. 9). The heaviest rainfall occurred in the vicinity of Mayfield. <br />The Weather Bureau precipitation gage at Mayfield caught 4,18 inches <br />of rain on March 29, and the two Geological Survey recording rain <br />gages in the Perry Creek basin measured 5.55 and 5.60 inches of rain. <br />The rain gages in the Perry Creek basin showed that all the rain of the <br />second storm fell between 1800 hours on March 28 and 0700 hours on <br />March 29. Most of the rain fell between 0200 hours and 0400 hours on <br />March 29_ Figure 9 shows the combined rainfall for the two storms in <br />the period March 24-29. <br />
