This Environmental Assessment (EA) proposes to restore westslope cutthroat trout to Cherry Creek, a tributary to the Big Hole River near Melrose, MT. Proposed methods include constructing a fish migration barrier approximately 1.5 miles upstream of the mouth of the stream, removing non-native brook trout and hybridized cutthroat trout using rotenone, and restocking non-hybridized westslope cutthroat trout.

This Environmental Assessment proposes to restore westslope cutthroat trout to McVey Creek, a tributary to the Big Hole River near Melrose, MT. This project proposes to accomlish its goal by: constructing a fish migration barrier, removing non-native brook trout upstream of the barrier using rotenone, salvaging native fish, including non hybridized westslope cutthroat trout, prior to treatment, and releasing the salvaged trout back into the stream once treatment is complete.

This Environmental Assessment proposes a native westslope cutthroat trout conservation project in Dyce Creek, near Polaris, MT. The proposed project includes removal of non-native brook trout and hybridized trout upstream of an existing barrier using rotenone. The treated reaches of Dyce Creek would be re-stocked with westslope cutthroat trout through natural colonization and transfer of genetically pure fish or eggs from the headwaters of the stream.

This letter is to notify you that I have made a decision regarding the proposed 160-acre grazing lease renewal on the Beartooth Wildlife Management Area (WMA) with Voegele's Inc. My decision is to move forward with the proposed action and to renew the lease. (Decision Notices - 03/25/2011)
In 1972, Montana Fish, Wildlife & Parks (MFWP) constructed a gabion fish barrier in the lower reaches of Elkhorn Creek of the Beartooth Wildlife Management Area. Westslope cutthroat trout (WCT) hybridized with rainbow trout were removed from approximately three miles of stream above the constructed barrier. Genetic samples collected in 1996 indicated the population was non-hybridized, but in 2002, additional samples indicated recent hybridization likely because of a failure of the gabion fish barrier. A sample collected in 2008 revealed that the WCT population in Elkhorn Creek had become a hybrid swarm with some level of hybridization in every individual; also, a brook trout was captured upstream of the gabion fish barrier. An alternate barrier site was identified approximately three miles upstream, which features bedrock control points and a narrow incised channel that greatly increases the functionality of the barrier. The proposed action is to construct a barrier to non-native fishes and remove heavily hybridized WCT upstream of the barrier with electrofishing or piscicides.
