Closures on Upper Gibbon River Drainage Begins Monday–September 2nd

Written by on August 30, 2019

From September 2nd to the 13th multiple areas of the Upper Gibbon river drainage in the central portion of Yellowstone National Park will close for fisheries work
Areas set for closure include Virginia Cascades Drive–Wolf Lake Trail–Wolf Lake Cutoff trail to Ice Lake and areas of the backcountry to the north and south between Canyon and Norris Junctions.
All campsites in the area will remain open. Closures may lift if the project is completed ahead of schedule.
Closures are necessary for park staff to continue work on a project to eliminate nonnative fish from the upper Gibbon River drainage, which drainage includes streams that flow out of Grebe, Wolf, and Ice lakes. Once nonnative fish have been removed, biologists will reintroduce fish species to the streams in this area.
The non-native species will be removed by using a fish toxin derived from tropical plants. Reintroduction of fish will begin in 2020 or 2021. These efforts are attempting to create refuge for the introduction of westslode cutthroat trout and Arctic grayling.
