<br />FLOODS OF JULY 24 IN THE VICINITY OF CLINCHMORE, TENN,
<br />
<br />By WlI.I.IU[ J'. RANDOLPli
<br />
<br />An intense rainstorm occurred over a section of the rugged slopes
<br />of the Cwnberland Mountains at the Anderson-Campbell County line
<br />(fig, 40) in the early morning of .July 24, The most intense part ofthe
<br />storm covered about 25 sq mi along the divide between the Cwnber-
<br />land and the Tennessee River basi!!s ..bout 6 miles southwest of Lake
<br />City, and the maximwn rainfall in this area occurred on the diVIde,
<br />There were no rain gages within the &rea of the greatest rainfall inten-
<br />~ity.; howeve:-, a bucket surv~y made by the Tennessee Valley Authority
<br />mdicated ramfall amounts m excess of 12 inches, most of which fell
<br />within the 3-hour period from 0130 to 0430 hours on .JUly 24, This is
<br />three times the amount of the 100-year 3.hour rainfall for this area
<br />(U,S. Weather Bureau, 1961), Rainfall gages about 15 miles north and
<br />northeast of the storm center recorded 4-5 inches.
<br />The streams in the storm area are relatively small headwater streams
<br />having steep slopes. Hardest hit 'were Stony Fork and Graves Gap
<br />Branch on the western side of the divide. From information obtained
<br />by the TY A from local residents, peak stages occurred abruptly, the
<br />ute of rIse on Stony Fork above Clinchmore (sta. 4) being about 10
<br />feet in 15 minutes. The peak had moved from the headwater to the
<br />mouth by about 0430 hours.

<br />
<br />There Me no stream-gaging stations in the area of heaviest runoff.
<br />Eight indirect measurements of peak discharge were made at miscel-
<br />laneoussites by the Geological Survey and by the TV A (table 30). The
<br />sites at which peak discharges were determined are shown in figure 40,
<br />The most outstanding flood (1,940 cfs per sq mi from an area of 6,34
<br />sq mil occurred on Stony Fork above Clinchmore.
<br />Damage from the flood was limited by the sparse settlement in this
<br />rugged country. However, ..lmost everything in the narrow valleys
<br />was damaged, Several bridges were washed away, roads were damaged
<br />by washouts or deposition of debris, and sever..l automobiles were
<br />demolished, Five persons drowned near Clinchmore when their house
<br />and several others were washed away, Several other houses were
<br />washed off their foundations or otherwise damaged. The railroad and
<br />the county road which paralled Stony Fork up to Clinchmore were
