high-intensity storm that culminated several days of widespread gen- eral rain. Precipitation began on June 28 and continued until July 3, when 3 inches fell in a 3-hour period atthe Weather Bureau rain gage in the village of Elm Creek, The village is about 13 miles downstream from the three gaging stations where peak discharges were measured (table 23), The amount of rainfall on July 3 at surrounding rain gages is given in figure 30. It is not known whether the amount of rain that fell on the basin above the gaging stations was greater or less than that at the village. The recurrence interval of a 3-inch rainfall in 3 hours at this site is about 25 years, according to the U.S. Weather Bureau (1961). The peak discharges at ,all three gaging stations were maximum during the 15-year period of record. That on Elm Creek near Sumner (sta,2) was 'about 6 times the previous maximum pE1ak and had a re- currence interval much greater than 50 years, The peak discharges on the tributaries that enter Elm Creek about 1 mile upstream (sta. 1) and 0.5 mile downstream (sta. 3) from station 2 were from about 1% times to 2 times that of the previous maximum discharges and had re- currence intervals of more than 50 years. Damage from the flood was slight and consisted mostly of hank and streambed erosion. Rock Creek 'in south-central Dundy County (fig. 31) flooded on July 3 and 5, each time following cloudburst-type rainfall, After the first downpour, a few local residents reported that their rain gages in- dicated about 8 inches, and several others reported that their 5-inch- oopacity gages had overflowed, The second storm not only dumped another 3 inches on the ltlready wet ground but was accompanied by hail that caused much damage to crops.
