They are now using a combination of high tech and low tech methods on the lake trout intruders. Lakers are being caught, fitted with transponders, and released, then tracked by a number of tracking stations around the lake. The intent is to pinpoint the key spawning areas (since they are mass spawners), then send in the commercial netters. I heard very encouraging reports in early June about the success of those methods, and following reports showed even greater optimism about finally turning the corner on removing the lakers and saving the native cutthroats.
