<br />lower reaches. The Arkansas River at Pueblo peaked at 11,000
<br />c.f.s. As the flood progressed downstream, the peak increased
<br />to 50,000 c.f.s. at La Junta and caused major flood damage to
<br />North La Junta. At'Las Animas, the peak measured 44,000 c.f.s.,
<br />but due to a very successful flood fight, no serious flooding
<br />occurred. The peak inflow to John llartin Reservoir was 811,OOO
<br />c.f.s., and the flood volume at the dam was 260,000 acre-feet.
<br />Very little inflow was produced by the upper tributaries. Foun-
<br />tain Creek had a peak of 5,000 c.f.s. at its mouth just below
<br />Pueblo. The St. Charles River had a peak of 20,000 c.f.s. at
<br />the mouth. The peak discharge for the Huerfano River at Under-
<br />cliffe was 11,300 c.f.s. The peak discharge for the Apishapa
<br />River near Fowler was 17,000 c.f.s. and for Timpas Creek near
<br />Rocky Ford, the peak was 7,500 c.f.s. The peak flow of the
<br />Purgatoire River near Las Animas was 70,000 c.f.s., but, as
<br />~ntioned above, the flood produced the largest peak of record
<br />in the entire lower reach of the Purgatoire River.

<br />g. Flood of June 1965. During the period 14-18 June
<br />1965, heavy precipitation occurred over the plains of south-
<br />eastern Colorado and northeaatern New Mexico. Heavy rains also
<br />occurred over the upper Fountain' Creek watershed and the head-
<br />waters of the South Platte River south of Uenver, Colorado. The
<br />storm produced over l8 inchall of rain fell in 3 days in the
<br />vicinity of Two Buttes in southeastern Colorado. In the area
<br />along the Arkansas River-South Platte River divide, northeast
<br />of Colorado Springs, as much as 12 inches of rain il\ 6 hours
<br />were reported. The storm produced unprecedented peaks from all
<br />the right bank tributaries of the Arkansas River from John
<br />~~rtin Dam to the Colorado-Kansas State line. Runoff from these
<br />tributaries produced floods of record on the Arkansas River
<br />from immediatelY below John Martin Dam to central Kansas. A
<br />severe storm cell northeast of Colorado Springs produced a maxi-
<br />mum peak flow of 124,000 c.f.s. on Jimmy Camp Creek. This
<br />approaches the probable maximum flow for this stream. Rainfall
<br />over the Black Squirrel Creek watershed produced a peak flow of
<br />141,000 c.f.s. These two small streams produced most of the
<br />flood on the Arkansas River from Pueblo to Las Animas. Jimmy
<br />Camp Creek was the primary contributor to the flood on Fountain
<br />Creek which resulted in the flood of record at Pueblo. The
<br />contribution from Black Squirrel Creek caused Chico Creek to
<br />produce 50,900 c. f.s. at the mouth. The Chico Creek and Fountain
<br />Creek flowa combined to give a peak of 102,000 c.f.s. in the
<br />Arkansas River at Avondala.
