For North Turkey Creek, the equations presented in the Miller and Thomas report were used to develop revised discharges for the 10-, SO-, 100-, and SOO-year floods. Revised hydraulic runs were computed for only the 100-year and 500-year floods because the revised 10-year and 50-year discharge values fell below the range of existing rating curves at major bridges, and information for extrapolating beyond these curves was not available. The 10-year flood profile for use in determining reaches, insurance zone designations. North Turkey Creek was estimated for Flood Hazard Factors, and flood For Bear Creek, revised peak flows were developed from a flood- frequency analysis at the stream gage in Morrison as presented in a report, entitled "Flood Hydrology of Foothill and Mountain Streams in Colorado", by R. D. Jarrett. Revised peak flows for the ungaged portions of Bear Creek were determined by utilizing the following equation with peak flows at the Morrison gage: Qs Qc (As/A(;)n where QS Peak flow in cfs at the ungaged site Qc = Peak flow in cfs at the Morrison gage As = Total drainage area at the ungaged site AC Total drainage area at the Morrison gage n = exponent The exponent n was derived from the discharge-drainage relationship obtained by utilizing the Thomas and Miller regression equations and specific basin information at the sites on Bear Creek from Morrison to the Jefferson County Line. The detailed study reach at Morrison was not revised because changes in peak flow values between those originally complete for the Flood Insurance Study (FIS) and changes computed by Jarrett would not produce significant changes in BFEs. Revised hydraulic analyses for 10-, 50-, 100-, and 500-year frequency floods were performed for the following reaches of Bear Creek: at Idledale, Kittredge to Evergreen, and above Evergreen Lake. The revised hydraulic analyses for both North Turkey Creek and Bear Creek utilized the computer information developed for the original FIS and was computed by use of the U. S. Army Corps of Engineers HEC-2 step-backwater computer program. Flood profile panels IlP to 38P for Bear Creek, and 272P to 286P for North Turkey Creek, have been revised to incorporate these results. The Summary of Di scharge Table and the Flood Insurance Data Table have been revised to reflect the new data for Bear Creek and North Turkey Creek. The revision also incorporated the Letter of Map Revision (LOMR) issued on December 4, 1987, for Coon Creek from South Kipling Street downstream to the corporate limits of the City of Denver. This LOMR was based on a channelization along Coon Creek in the 47
