<br />UGZ376 <br /> <br />Table 1. <br /> <br />Locations/situations where nonnative fish species can be stocked <br />on a routine basis. Appendix A discusses the rationale for <br />concluding that stocking these species/locations/situations are <br />consistent with recovery of the endangered Colorado River fishes. <br />Appendix A also provides a map delineating critical habitat and <br />the 6,500 foot mean sea level contour line. <br /> <br />Species <br /> <br />all salmonids currently in <br />the basin (family Salmonidae) <br /> <br />triploid grass carp <br />(Ctenooharvnqodon idella) <br /> <br />Location/Situation <br />all waters in the upper basin. <br /> <br />triploid fish (certificate of triploidy <br />required prior to stocking). <br />isolated2 ponds and reservoirs within <br />critical habitat above the 40 year <br />floodplain'; <br />ponds which are screened' to prevent <br />escapement; <br />isolated ponds or reservoirs or screened <br />connected ponds or reservoirs at or below <br />6,500 feet mean sea level located at least <br />5 vertical feet' above the ordinary high <br />water lines of waters that are not <br />designated as critical habitat. <br />isolated ponds or reservoirs located above <br />6,500 feet mean sea level. <br /> <br />redside shiner <br />(Richardsonius balteatus) <br /> <br />threadfin shad <br />(Dorosoma oetenense) <br /> <br />lakes and ponds above Flaming Gorge Dam. <br /> <br />Lake Powell. <br /> <br />2 isolated refers to waters with no surface connection to other waters. <br /> <br />· The 40 and 100 year floodplains related to critical habitat will be <br />mapped and made available to interested parties by October 1994. <br /> <br />, Screened based on State requirements. <br /> <br />S 5 feet above OHW approximates an elevation of 50 to 100 year flood <br />events based on the professional opinion of FWS hydrologists. This value will <br />be adjusted during the next 6 months based on the results of site-specific <br />hydraulic and hydrologic investigations. <br /> <br />4 <br />
