The flood-producing storms followed a <br />relatively wet periOd and as much as 14 in of rainfall in a few hours was reported, <br /> <br />o <br /> <br />Previous record discharges on many tributaries with drainage areas on the plains were exceeded, <br />sometimes severalfold, Snowmelt was not a contributing factor on any of the streams with head- <br />waters on the Palmer Ridge, east of the front range, <br /> <br />Showers and thunderstorms developed east of the Rockies in central Colorado on the morning of <br />June 16. By early afternoon, the storms were located along a north-south line, roughly from Denver <br />to Pueblo, In the northern part of the area, the storms coincided with the major axes of the Plum <br />Creek and the Cherry Creek Basins This condition combined with the already saturated ground <br /> <br />84 <br />
