<br />city was !t1creascu 1.0 40,000 see-ond-feet In Denver where the
<br />Cherry Creek flood of 1912 had a penk of about 11,000 second-feet,
<br />the channel capacity was increased from 6,000 to 10,000 second-feet;
<br />in Colorado Springs, after the peak flow of 50,000 second-feet. on
<br />lvfonument Creek in 1935, the channel cupacity was increased from
<br />10,000 to 50,000 scc0and-feet.
<br />(4) As the cities grew und were able to finance flood-protection
<br />measures, they planan~d not merely for the grcatC'st flood that hud
<br />occurred since settIellll1:~nt, but for the greatest probable flood as
<br />detC'rmined from aoc1llIffiuluted meteorologic and hydrologic data.
<br />Pueblo was the first city to take such action. The peak flow of
<br />103,000 second-feet dll'lring the A,rkansas River flood of 1921 was two
<br />and a half times that oCthe flood of 1894. ~rindful of the inadequate
<br />protection provided dter the 1894 flood, provision was made by
<br />Pueblo for protectiollll against a flood of 175,000 second-feet. The
<br />Cherry Creek flood of1933 had a peak flow of 15,000 second-feet in
<br />Denver, and although this was due chiefly to the failure of Castlewood
<br />Dam, the city soon afterward constructed a detention reservoir
<br />designed to reduce a peak flow of 70,000 second-feet to 10,000 second-
<br />feet, the channel capacity of the creek in Denver.
<br />Improvement in flood protection by increasing
<br />has been confineo almost entirely to the cities, and
<br />adequate protection has been done elsewhere.
