<br />in November 1866, the summer of 1883, and July 1886. It is estimated <br /> <br />. <br /> <br />that the flood of 1866 exceeded 30,000 c.f.s. at Trinidad. The peak <br /> <br />discharge for both the 1883 and 1886 floods was about 25,000 c.f.s. <br /> <br />at Trinidad. In September 1904, a major flood hit Trinidad. This <br /> <br />was the first major flood for which reliable records are available; <br /> <br />and when compared to those of historical record, it was the largest <br /> <br />flood at Trinidad since 1859. The U.S. Geological Survey estimated <br /> <br />that a peak discharge of 45,400 c.f.s. occurred at Trinidad on <br /> <br />September 30, 1904. This flood affected 370 acres of urban, residential, <br /> <br />business, railroad and industrial properties, and 4,580 acres of rural <br /> <br />lands. Damages from this flood were estimated in excess of $1,000,000 <br /> <br />(1904 prices). Subsequent damaging f1oodflows that exceeded the 15,000 <br /> <br />c.f.s. channel capacity through Trinidad are shown on Table 2. <br /> <br />Tab Ie 2 <br /> <br />FLOODS ABOVE 15,000 CUBIC FEET PER SECOND <br />JANUARY 1921 THROUGH SEPTEMBER 1960 <br />TRINIDAD, COLpRADO <br /> <br /> Peak Discharltes <br />Flood Year Date of Peak Without Res.
