<br />July 9, 1990 <br /> <br />Surface Runoff in Adams County <br /> <br />Approximately 1.5 inches of rain fell over Adams County <br />flooding fields. Water 4 inches deep flowed across a 40 foot <br />length of Highway 79 for 3 to 4 hours. Witnesses reported <br />that it took two trucks and three men 4 hours to haul away <br />debris from the flooding. At the time of the flooding, there <br />were no culverts or drainage ditches in the area. <br />Construction of new ditches were underway as of February <br />1991. <br /> <br />Sources: <br /> <br />Darl McClaren, Highway Patrol Department <br />of Highways Drainage Structure Flood <br />Summary <br /> <br />July 9, 1990 <br /> <br />Local Drainage at Denver <br /> <br />A storm moving northeasterly over Stapleton International <br />Airport dropped up to 1.34 inches ofrain in 1.5 hours. Up <br />to 0.60 inches fell in the first 15 minutes. Flood water <br />reached up to 10 feet deep in some underpasses. At 38th <br />and Wynkoop, a 13.5 foot underpass still had 7 feet of <br />water in it one hour after the storm. The flooding seemed <br />to be caused by insufficient drainage capacity on the <br />highways and roads. Injuries included a few broken legs. <br />Many cars were flooded or stranded. <br /> <br />Sources: <br /> <br />Denver Post, 07/10/90 <br />Rocky Mountain News, 07/10/90 <br /> <br />July 20, 1990 <br /> <br />East Drainageway at Ordway <br /> <br />Over two inches of rain were reported to have fallen.
