Feasibility analysis of translocating western pearlshell mussels into the Cherry Creek Native Trout Project Reach on the Flying D Ranch in Montana E3a2632f-3d39-4d1e-bcb0-8d61103b18ba Year: 2013 potential of a live population (D-rank viability), but the two other streams containing WERE shells, the Ruby and Jefferson Rivers, only had relic shells (>10 years old)and are not likely to contain live populations. Of fifty-one stream reaches in the Madison River basin that had been surveyed for WERE prior to 2012 (Appendix B), only one of those reaches was ranked as having a viable WERE populat

Of fifty-one stream reaches in the Madison River basin that had been surveyed for WERE prior to 2012 (Appendix B), only one of those reaches was ranked as having a viable WERE population (Duck Creek, B-rank)(Map 4). We did not return to Duck Creek in 2012 to collect mussels for the fish health screening, but plan to revisit this site in 2013 to WEPE pre-2t)12 surveys Viability O B-Good viable pop. o C-Fair population O D-Declining population • F-No evidence of WEPE • H-Historical Evidence Map 4.
