distances, Flood of 1867, A flood in May 1807 caused the mmoval of Fort Lyon to a place 17 miles farther west. The rainfall record af Fort Lyon was as follows: May:24-26, 1.80 inches; May 29, 1.00 inch; May 30, 1.15 inches; a total of 3,95 inches, as compared with a normal rainfall of 2 inches for the entire month, This flood was probably caused chiefly by melting snow, as the Canon City Record of June 2, 1894, quotes historian B,F, Rockafellow, as saying that the melting of the snow at the time of the flood of 1867 caused "the streams (in the vicinity of Canon City) to become swollen into rushing torrents," The Bent County Democrat, June 15, 1921, quotes John W, Powers, county clerk, as follows: "I have heard my mother tell of the great flood of 1867, which must have surpassed the one of this month, At the time to which she referred both the Arkansas and the Purgatoire were at flood stage simultaneously, with the result that the Arkansas River in the section where Lamar now stands was a solid body of water from the sand hills on the south side to the first upland on the north side of the river, Flood of 1875, The next flood of record on the Arkansas River is that of September 16, 1875, which was caused primarily by high water in the Purgatoire River and therefore affected the Arkansas River chiefly below the Purgatoire, The Las Animas Leader, Septembm 18, 1875, reported: "At Fort Lyon (4 miles below the mouth of the F'urgatoire) the water was 4 feet higher than known before, The bottom land between the bridge and the post trader's (a distance of three-fourths of a mile) was a swift, raging flood," The upper river was also in flood as far north as Pueblo, but as the Pueblo press gave little space to it the flood at that point was evidently not serious, Flood of 1884, Rain and runoff from meltin9 of the heavy snow cover in June 1884 caused a flood on the Arkansas River between the Grand Canyon, jllSt above the Royal Gorge, and Pueblo, The Canon City Record, June 28,1884, stated that the water was:2 feet deep on the railroad tracks in the Grand Canyon, Flood of 1886, A flood of considerable magnitude on the lower Arkansas River, probably below the mouth of Purgatoire River occurred July 20-25, 1886, This flood did not extend to the upper river, as the Pueblo gaging station showed a maximum of only 3,080 cfs on July 21, The rainfall was apparently heaviest in the vicinity of Las Animas and LaJunta, At the former place the rainfall was 3,36 inches July 24,25, and 4,66 inches for the month, or more than twice the normal. At pueblo the rainfall for July was only 0,39 inch, Flood of 1889, Rains on August 9, 1889, were followed by a flood that caused overflow from Grape Creek at least as far east as Pueblo, These rains must Ilave been of thE! cloudburst type in the Arkansas Valley, as at none of the rainfall stations was the recorded pmcipitation heavy except at Pueblo, where 1,02 inchE!s of rain in 1 hour on August 9 was recorded, This intense rainfall, with a temperature of 98 degrees before the storm, indicates a cloudburst. From the account of the Grape Creek flood it appears that the flood on the Arkansas River came primarily from that source, It was evidently augmented by rain at other points, The Denver Republican states that rain began falling about 5:30 pm on August 9, and floocled the region around Pueblo, and that a "terrible and disastrous rainstorm visitnd Florence in the evening and lasted 2 hours, The Denver & Rio Grande is having lots of trouble caused by the cloudburst of Friday night. The Hardscrabble bridge washed out" Flood of 1893, In 1893, one of the driest years of mcord at Pueblo, a flood occurred on ,July 26, which reached a stage 10 feet lower than that of the flood of 1921, The river rose 8 feet in 2 hours at Pueblo, No Colorado Flood Hydrology Manual 4.21 DRAFr
