<br />LESSONS of RECOVERY' A REViEW of ThE 1997 COLORAdo Flood DisASTER <br /> <br />Weldona <br /> <br />Intense rainfall in the vicinity of Weldona produced flood flows in Schaefer Draw and adjacent tributaries that <br />caused two irrigation ditches to breach, resulting in combined flows that inundated 80 percent of the <br />community to depths of four to five feet. In and around Weldona, the flooding caused approximately $1.1 <br />million in damages to 38 single family homes, six businesses, Weldon Valley High School, the local Catholic <br />Church and annex, a postal facility, roads, bridges, embankments and crops. <br /> <br />Logan County <br /> <br />According to both long-time residents and available flood discharge estimates, the 1997 Pawnee Creek <br />flood was comparable to, if not greater than, the previous significant flood event which occurred in 1965. <br />In the narrower, upper reaches of the basin, floodwaters that were basically confined to the channel <br />damaged roads and bridges and eroded stream banks. State Highway 14 between Sterling and Fort Collins <br />was closed for a week for flood repairs and another bridge just across the border in Weld County - on State <br />Highway 71 between Stoneham and Kimball, Nebraska -- was totally destroyed, closing the highway for two <br />weeks while a detour was built. <br /> <br />In addition to the access problems and other economic impacts caused by the temporary loss of the two state <br />highway bridges, the flood added over 100 road and bridge projects to the Logan County maintenance and <br />construction schedule, including major repairs to the bridge on County Road 7 and the replacement of four <br />large culverts on County Road 11.2. Many of the damaged roads represented vital farm-to-market links that <br />had to be repaired prior to the summer's wheat harvest in order to avert financial losses for area farmers. <br /> <br />Downstream, overbank flooding completely inundated bridges, miles of roads and approximately 13,700 acres <br />of agricultural lands. Countywide, including the community of Atwood and the City of Sterling, approximately <br />1,400 residences and more than 200 businesses were affected by the flood. One estimate indicates that the <br />flood caused nearly $20 million in damages countywide, including $9.7 million residential, $6.8 million <br />agricultural. $1.4 million commercial, $1 million road and bridge, and $100,000 in damages to the railroad <br />between Atwood and Sterling (ICON Engineering, Inc., 1998). <br /> <br />Atwood <br /> <br />At the lower end of the basin near the community of Atwood, wide floodplain areas exist and excess runoff <br />is partially contained by the embankments of US 6 and the railroad, flooding farm and pasture lands in <br />the vicinity. The manmade embankments, referred to as the Pawnee Overflow, typically divert flows to <br />the northeast into the City of Sterling, where homes and businesses in some parts of the city are subject to <br />repetitive minor flooding (RTi, 1998). <br /> <br />At approximately 3:00 p.m. on July 30,1997, Pawnee Creek overflowed its banks and backed up behind the <br />highway and railroad embankments, inundating most of the homes and other buildings in Atwood to depths of <br />up to four feet. According to building inspectors who placed red (unsafe) and yellow (major repairs needed) <br />tags on damaged homes in Atwood, 13 homes were destroyed, 27 suffered major damage, and 15 more had <br />minor to moderate damage. <br /> <br />Eight of the homes had to be demolished because they were structurally unsafe or because repair costs were <br />prohibitive. Pawnee floodwaters left the entire town covered in mud and debris, including large, round hay <br />bales, railroad ties and utility poles. Individual well systems were damaged or destroyed throughout town. <br /> <br />COLORAdo OffiCE of EMERGENCY MANAGEMENT <br /> <br />5 <br />
