Cherry Creek Native Fish Introduction Project Supplemental Environmental Assessment

Species Stocking - 06/30/2005

This Supplemental Environmental Assessment (EA) has been prepared for the Cherry Creek Native Fish Introduction Project. This Supplemental EA clarifies the original 1998 EA and proposes that Montana Fish, Wildlife & Parks (FWP) have the latitude to use rotenone in Cherry Lake, should the need arise. Treatments in 2003 and 2004 using antimycin did not result in a complete eradication of Yellowstone Cutthroat Trout in the lake as anticipated in the 1998 EA. *Note - Hardcopies of Appendix B are avaliable by request at: FWP 1400 S 19th Ave. Bozeman, MT 59718 (406) 994-4042 *Please note the following correction near the top of page 11 of this EA: "The calculation of the antimycin criteria is as follows: (0.0017 (instead of 0.5) mg/kg-day (RfD) * 70 kg (BW)/(2L/day (DI)) Based on a maximum concentration of 12 ppb that will be used in this project, the maximum concentration that would occur in Cherry Lake is 12 micrograms/L, which is 5 (instead of 1,458) times less than the safe level calculated by DEQ. This is the same concentration that has been used in Cherry Lake in 2003 and 2004."
