In May 2006, Montana Fish, Wildlife & Parks (MFWP), along with Bonneville Power Administration and the Forest Service, issued their Records of Decision for the Environmental Impact Statement for the South Fork Flathead Westslope Cutthroat Trout Conservation Program. The purpose of this program is to protect the genetic purity of westslope cutthroat trout in the South Fork Flathead by removing hybrid trout from headwater lakes and restocking with genetically pure westslope cutthroat trout. To address the issue, the three agencies prepared an EIS that considered and analyzed three action alternatives (which included one preferred alternative), and a fourth "No Action" alternative;
- Alternative A: No Action - status quo management
- Alternative B: Proposed action - use the piscicides antimycin and rotenone with combined (livestock and motorized) transport and application methods
- Alternative C: Fish toxins -use motorized/mechanized transport and application methods
- Alternative D: Suppression techniques and genetic swamping.
Montana Fish, Wildlife & Parks has made a decision to implement Alternative B (proposed action) as described in the Record of Decision and the EIS.
