The battle to keep non-native lake trout out of the Quartz Creek drainage continues . . .
Following National Park Service approval and an environmental analysis, Glacier National Park officials will move forward with modifications and improvements to the existing Quartz Creek fish barrier to try and suppress lake trout and other non-native fish from getting into Quartz Lake, the park announced Monday.
Located in the North Fork of the Flathead River drainage and the park’s North Fork District, Quartz Lake is believed to be one of the last remaining strongholds for bull trout in park waters west of the Continental Divide. The lake was believed to be the largest on the west side of the park accessible to lake trout but not yet colonized by them. However, lake trout were detected in 2005, threatening the long-term persistence of the Quartz Lake bull trout fishery.
