<br />A partial-record gage equipped with stage-rainfall recorder, Head-
<br />gate Draw at upper station near Buffalo (sta. 2), was destroyed prior
<br />to the peak, at a stage about 1.75 it below the peak stage. At that time
<br />the rainfall recorded was 2.05 inches in 2 hours 25 minutes. The rain-
<br />fall intensity for the last 18 minutes recorded was 2,23 inches per hour.
<br />The high rates of unit runoff at these sites are of particular interest:
<br />4,990 cfs per sq mi at Headgate Draw at upper stati~>n. (sta. 2), 2,670
<br />cfs per sq mi at Headgate Draw at lower station (sta, 3), and 1,450
<br />cfs per sq mi at Powder River tributary (sta. 4). Damage from the
<br />June 15 floods was limited to county bridges and roads and to ranch
<br />lands on the flood plains.
