<br />
<br />Delailed information on Dry Creek from its mouth in Larimer County, through the City of Fort
<br />Collins, and continuing upstream to a point again in Larimer County, is provided in the report
<br />by the USACE, Omaha District, and was the basis for the 1983 revision to this study. Both the
<br />USACE's report and this report are in complete agreement for Dry Creek (Reference 6).
<br />
<br />Additional information on Boxelder Creek is provided in a study by Simons, Li & Associates,
<br />Inc., in 1981 (Reference 2) and by the NRCS report in 1983 (Reference 27). Information from
<br />these reports was utilized by the USBR in its 1992 study of BoxeIder Creek.
<br />
<br />In August 1981, Simons, Li & Associates, Inc., completed a Master Drainageway Planning Study
<br />for BoxeIder Creek and Cooper Slough in the vicinity of the City of Fort Collins (Reference 2).
<br />The approximate flood boundaries for Boxelder Creek were laken from this study.
<br />
<br />The Flood Insurance Study report for the unincorporated areas of Larimer County, Colorado, is
<br />presently being revised to reflect the updated information for the Cache La Poudre River, Spring
<br />Creek, and Cooper Slough. The Larimer County Flood Insurance Study report is in complete
<br />agreement for these streams with the City of Fort Collins Flood Insurance Study report.
