Montana Fish, Wildlife and Parks has released an Environmental Assessment for a proposal to restore Arctic grayling into several waters in Southwestern Montana. Unlike the Grayling Creek project in YNP, where NPS is instituting a "clean slate" approach (killing all non-native fish prior to release of grayling and westslope cutthroats), Montana FWP is not planning to "manipulate" existing trout populations in the targeted streams/lakes.
