1 <br />' 1.0 INTRODUCTION <br />' 1.1 P ose <br />This report was prepared to guide public and private entities interested in or affected by the <br />potential stocking ofnon-native fish species inoff-channel ponds (public and private). Inundation <br />during flood events is possible at the pond sites and could affect endangered fish. The report <br />delineates the 50-yeaz and 100-year floodplains for the reach of the Gunnison River designated <br />1 as "critical habitat" by the U.S. Fish and Wildlife Service (Service). The report allows interested <br />parties to determine preliminazily whether particular ponds are in the 50-year and 100-year <br />floodplain of the Gunnison River. <br />1.2 Acknowled ements <br />' The assistance and cooperation in supplying information of the individuals, agencies, firms, and <br />organizations listed below are appreciated and gratefully acknowledged: <br />' Larry F. Lang - Chief, Flood Control & Floodplain Management Section, <br />Colorado Water Conservation Board (CWCB); <br />Brian Hyde - Resource Scientist III, Flood Control and Floodplain <br />Management Section, CWCB; <br />Jerry (Ed) Vail - Hydrologist, United States Geological Survey <br />' Bob McCabe - Colorado State Engineer's Office, Division 5 <br />U.S. Army Corps of Engineers, Sacramento District <br />Federal Emergency Management Agency <br />' 1.3 Related Flood Studies <br /> <br /> <br /> <br />n <br /> <br />The Federal Emergency Management Agency prepazed Flood Insurance Studies (FIS') with <br />accompanying Flood Insurance Rate Maps for the City of Delta and unincorporated Delta County, <br />both dated 8/91 (References 1 & 2) and for the City of Grand Junction and unincorporated Mesa <br />County, both dated 7/92 (References 3 & 4). The FIS' include peak flow values for 50-year and <br />100-year floods in the vicinities of Delta and Grand Junction, Colorado, along with detailed <br />floodplain mapping. The flow values from these studies and the accompanying detailed <br />floodplain delineations have been incorporated into this report. <br />The reports referenced above aze available at the offices of the Colorado Water Conservation <br />Boazd, at the Federal Emergency Management Agency (Region VIII), at the Cities of Delta and <br />Grand Junction, and at Mesa and Delta Counties. <br />1 <br /> <br />
