Inundation during flood events is possible at the pond sites and could affect <br />endangered fish. The report delineates the 50-year and 1 DO-year floodplains for the reach of the <br />Colorado River designated as "critical habitat" by the U.S. Fish and Wildlife Service (Service). <br />The report allows interested parties to determine preliminarily whether particular ponds are in the <br />50-year and I DO-year floodplain of the Colorado River. <br /> <br />1.2 Acknowledgements <br /> <br />The assistance and cooperation in supplying information of the individuals, agencies, firms, and <br />organizations listed below are appreciated and gratefully acknowledged: <br /> <br />Larry F. Lang <br /> <br />Chief, Flood Control & Floodplain Management Section, <br />Colorado Water Conservation Board (CWCB); <br /> <br />Brian Hyde <br /> <br />Resource Scientist III, Flood Control & Floodplain <br />Management Section, CWCB; <br /> <br />Jerry (Ed) Vail <br /> <br />Hydrologist, United States Geological Survey <br /> <br />Bob McCabe <br /> <br />Colorado State Engineer's Office, Division 5 <br /> <br />U.S. Army Corps of Engineers, Sacramento District <br /> <br />Federal Emergency Management" Agency <br /> <br />1.3 Related Flood Studies <br /> <br />The Federal Emergency Management Agency prepared Flood Insurance Studies (FIS') with <br />accompanying Flood Insurance Rate Maps for the,following communities: the City of Rifle and <br />unincorporated Garfield County, both dated 1/86 (References 1 & 2); the Town of DeBeque, <br />dated 4/89 (Reference 3); the Town of Parachute, dated 9/91 (Reference 4); the City of Grand <br />Junction, the Towns of Palisade and Fruita, and unincorporated Mesa County, all dated 7/92 <br />(References 5,6, 7, & 8). Although the Town of DeBeque is located along the Colorado River, <br />the DeBeque FIS did not provide any floodplain information for the Colorado River. It is simply <br />listed for information purposes. <br /> <br />A report titled "Floodplain Information Report, Parachute Creek, Colorado River in the Town of <br />Parachute, Colorado" was prepared by a private consultant in October of 1989 (Reference 9). <br /> <br />1 <br />
