Success on the Lake

Lake trout suppression is aving a measurable impact on imperiled cutthroat trout

The additional funds added one more gillnetting boat, working longer hours for an extended season, in an effort to reduce the number of invasive lake trout preying on native Yellowstone cutthroat trout. Learn more>>

The National Park Service (NPS) recently announced that 300,000 invasive lake trout were removed from Yellowstone Lake from May through October 2012, compared to 220,000 removed in 2011.

NPS’s latest sampling of immature Yellowstone cutthroat, taken annually since 1945, produced 20,000 young fish—more than double the number caught last year. This seems to indicate that the more aggressive suppression efforts are having a positive effect on cutthroat population numbers.

One of Yellowstone National Park's top priorities is to save the Yellowstone cutthroat trout -- an essential link in Yellowstone's ecosystem -- before it's too late. Since July 1, 2012 YPF has raised $158,765 towards this fiscal year's goal of $1 million to continue boosting the park's lake trout suppression effort in 2013.
