Glacier Park is trying to keep non-native lake trout out of Quartz Lake . . .
Glacier National Park officials are seeking public comment on a project that would modify and improve a fish barrier designed to stem the invasion of lake trout in Quartz Lake.
Considered one of the last best strongholds for native fish in the entire Columbia River Basin, Quartz Lake’s native fish populations include bull trout, which are classified as a threatened species under the Endangered Species Act, as well as westslope cutthroat trout and mountain whitefish.
Native fish populations in Glacier National Park have been compromised by the invasion of non-native fish species into the park’s lakes and streams, and lake trout are being targeted as the chief culprit.
