However, thunderstorms in Kahaluu Valley <br />caused peak discharges that were three times as large as the previous <br />maximums on two stream.s in more than 30 years of record. <br />The greatest damage from the February floods on Oahu occurred in <br />the Kaneohe and Kahaluu areas, About 30' homes were severely dam- <br />aged in Kaneohe from flooding on Kamooalii Stream above the Luluku <br />Street culvert (sta. 24). Two persons were drowned, and property dam- <br />age was about $340',0'0'0', In the Kahaluu area about 30'0' acres were inuu- <br />dated, and the flooding damaged homes, automobiles, and crops. A store <br />owner stated that the depth or water in his store was greater than that <br />from any other flood in 15 years, The U.S. Soil Conservation Service <br />estimated the floGd damage in the Kahaluu area at $240',000'. <br />. The storm or early February brought heavy rain to Molokai (fig, 6). <br />Showers began at 1930' hours on February 2, became more intense at <br />150'0' hours on February 3, and ended at about 230'0' hours-most or the <br />rain fell in an 8-hour period. In the western one-third or the i.;;land only <br />a rew rain gages caught more than 2 inches of rain, and several caught <br />less than half an inch, More than 3 inches fell .:bove the 1,aO'O'-foot ele- <br />vation on the western slopes in eastern Molokai, and at one' gage 'at <br />1,45O'-root elevation,.the rainfall was estimated at 4,6 inches. The great- <br />eSt rainfall rea.ding was 9.0'3 inches at Puuohuku, ",bout one-half of its <br />mean annual rainfall, and at Mapulehu, the only gage on the south- <br />eastern coast, the reading was 5.89 inches. <br />Floods occurred in a few streams in eastern Molokai (table 5)..The <br />peak stage' at Halawa'Stream near Halawa (sta. 1)' was over the top <br />of the gage shelter, and the peak discharge was more than two times the <br /> <br /> <br />EXPLANATION <br />.5,. <br />Flood-detenIiination point <br />NTUllber-C01'TtlBpOndsto <br />tkatintabLl5 <br /> <br />5 0 <br />1 t ,_" , <br /> <br />5 MILES <br />, <br /> <br />FI~uRE 6.-Location of floOd-d-eterin.inatiori. pOtiitS,'~'oods of Thbruarylg Molokai, <br />Hawaii.'
