<br />, <br /> <br />FLOOO HISTORY <br /> <br />Pawnee Creek and Sand Creek have often been considered together <br />when the topic of flooding has been discussed. This is because <br />Pawnee Creek can overflow into the Sand Creek flood plain at <br />Sterling. For purposes of this study, floods unique to Sand <br />Creek are not included. <br /> <br />Flooding along Pawnee Creek can occur as a result of general <br />rains over the entire basin or from local storms on individual <br />tributaries to Pawnee Creek. An example of local flooding is the <br />fairly recent flood of July 30, 19B9. This particular event was <br />not an extreme flood but it did produce about 5000 cfs on Pawnee <br />Creek near Colorado Highway 14. Field observations indicated the <br />major portion of flood waters came from the South Pawnee Creek <br />and Raymer Creek. <br />The following are accounts of two major floods on Pawnee Creek: <br /> <br />May 1935 - Hug~ Pawnee flood dar.aged the railroad between <br />Sterling and Atwood, perhaps the biggest in many years. <br />This flow swept out several hundred yards of grade on <br />Highway 14, west of Sterling, washed out the approaches <br />to Sterling bridge north of Atwood, and sent a tide <br />flowing over Highway 6 and the bridge and tracks of <br />railroads at the Pawnee bridge. <br />June 1965 - Flooding occurred June 14 and 15 as the <br />result of heavy rainfall on Pawnee Creek. Considerable <br />damage occurred throughout the lower reaches of the <br />watershed. South of Sterling, near Atwood. flood water <br />overtopped Higt~wi>Y 6 and i:'ailroad tracks. f'a>l:1cc Creek <br />flood waters also flowed in a northeasterly direction <br />along Highway 6 and inundated portions of sterling. <br />Other dates of listed flooding include IBB3. 1894, 1914, and <br />1921. <br /> <br />I, <br />, <br /> <br />J~ <br />~ ~ <br />'" " <br />~~ <br />'f-~ <br />(I' " <br />, ~ <br />-,~ <br />:l><>- <br />'-I.'~ <br />,?;)'<l> <br />~ <br /><; <br />1:3 <br /> <br />I <br />I <br /> <br />~~':1, <br />~"'''' <br />"...... <br />! i;;~i' <br />1 ~~t <br />~, ~, <br />I.l: ';) , , <br />1;/ <br />" <br />~ <br />ii <br />~ <br /> <br />8 <br /> <br /> <br />I":' <br />" <br /> <br />, <br /> <br />". <br />,"f."_i1i <br />if <br /> <br />p <br /> <br />1111 <br />" I <br /> <br />',~' <br /> <br />" <br /> <br />~ <br />. . <br />.
